Service technicians have no problem recognising breakdowns and carrying out machine diagnostics, Scania EMS Fault Codes, plus they are familiar with equipment from a variety of manufacturers.
The Scania EMS system consists of a control unit and sensors for speed, charge air temperature and pressure, coolant temperature, oil pressure, accelerator pedal/throttle actuation which constantly emit signals to the control unit. With the aid of this input data and the set control program, the correct amount of fuel and the correct injection time are calculated for each unit injector (PDE) under the specific operating conditions. The EMS system sensors can also be used to emit signals to the instruments in the instrument panel. The control unit constantly monitors the sensors to make sure they are operational.
The control unit contains monitoring functions to protect the engine in the event of a fault which would otherwise damage it. In the event of a fault, e.g. alarm level for low oil pressure or high coolant temperature, the control unit sends a CAN message to a coordinator. When the EMS control unit or the coordinator detects a fault, the diagnostics lamp on the instrument panel(s) comes on, and it stays on as long as the fault is active. At the same time, a fault code is generated which can be read off via the coordinator on the diagnostics lamp in the form of a flash code when the diagnostics switch is activated.

An active DTC limits the maximum engine torque to approximately 40%.
An active DTC cannot be deleted from the control unit. When the malfunction has been resolved, in order for the malfunction code to become inactive, the control unit must ensure that the malfunction has been eliminated.
Elimination:
Check the electrical components, electrical connectors and wiring. Check for any visible faults that cause the charge air cooler to degrade.
In order for the control unit to verify a fault, it must perform a sequence of checks. When the control unit performs a complete sequence of checks without detecting a fault, the fault becomes inactive.
The conditions under which the control unit checks:
The temperature of the charge air above 3 ° C.
The difference between the charge air temperature and the outside temperature must be less than 10 ° C for 10 seconds.
The control unit must perform the test in four consecutive cycles. This means that the power must be turned off and on four times using the ignition key at 10-second intervals.
You can go to the fault code monitoring function and view the fault code. There you can see if the conditions under which the control unit confirms that the fault has been eliminated have been satisfied.When conditions are satisfied and a check is performed, the status of the DTC is displayed during the check process. If the DTC is under review, the control unit has detected a fault. If the fault is resolved, the fault code becomes inactive. Clear the fault code.
Using the ignition key, turn off and turn on the power three times in a row at intervals of 10 seconds to deactivate the test lamp.

Possible reasons:
Leakage.
Malfunction in high pressure pump, fuel metering inlet valve or fuel pressure sensor. Insufficient fuel supply from the low pressure side.
Notes:
Black smoke may be emitted from the engine.
As long as this DTC is active, the engine power is limited and the EGR system is deactivated. The fault code cannot be cleared while the fault is present.
Elimination:
If there are other trouble codes for any other injector, perform troubleshooting for the injectors.
If a trouble code 0094 has been generated for a small leak on the high pressure side, the cause should be corrected first. Perform low-side troubleshooting, following La’s “troubleshooting tree” in document 03: 14-01, edition 2.
Check supply pressure, fuel metering inlet valve, high pressure pump, booster pump, and check for leaks.
If the operating time since the generation of the fault code exceeds 10 hours, empty the EGR cooler, as there is a danger of condensation in the air-cooled EGR cooler after the EGR system is turned off.

Title:
Pressure in the engine power system Fault:
The pressure in the fuel line is well below the set value.
The reasons:
Possible causes of failure:
One of the two relief valves opens at too low a pressure. The fuel shut-off solenoid valve remains closed.
The fuel filter is clogged.
Air in the fuel or lack of fuel in the tank. Malfunctioning booster pump.
Significant fuel leak from the system. Notes:
For the formation of a fault code, it is necessary that the pressure of the injector supply be below the permissible value for at least 7 seconds. This time period was set to avoid writing code due to short-term pressure fluctuations not caused by functional deviation.
If the signal voltage is outside the acceptable range, the control unit uses the preprogrammed value.
With this fault, the maximum torque of the engine is reduced by approximately 40% while the fault continues to be present.
A fault code can self-destruct if its existence is regarded as temporary. After a certain period of time, when the problem does not occur, the fault code will be erased.
A malfunction code affects the emission of nitrogen oxides (NOx) by the car, and a warning lamp lights up in the instrument cluster, warning of high levels of pollutants. On vehicles with NOx control, a text message is also displayed.
Cars with NOx control
An active DTC cannot be deleted from the control unit. When the malfunction is resolved so that the malfunction code becomes inactive, the control unit must ensure that the malfunction has been eliminated.
Elimination:
Check for fuel in the tank and bleed the fuel system to remove air from it. Check the opening pressure of both relief valves.
Check the position of the fuel shut-off solenoid valve. Check the condition of the fuel filter.
Check the fuel priming pump.
Check the tightness of the fuel system.
If a malfunction code is generated when the engine is running by inertia (for example, when the vehicle is going to descend with the accelerator pedal fully released), to facilitate troubleshooting, you can use the “Stored operational data” option on the “Pressure” tab supply “(” Supply Pressure “). If the supply pressure deviation over a certain time interval is 1.0 bar or more, the fuel filter may be clogged. If there is only a slight deviation in
the supply pressure, this may mean that the bypass valve is stuck. To make sure the problem is resolved.
Turn on the ignition and wait at least 15 seconds. If the fault is resolved, the fault code becomes inactive. Clear the fault code.
To turn off the alarm, turn off and turn on the ignition with the ignition key three times in a row at 10-second intervals.

Malfunction of high pressure pump, fuel metering inlet valve or fuel pressure sensor. Fuel metering inlet valve sticking or leaking.
Diffuser sealing rings in high pressure pump damaged. Notes:
Abnormally high noise generated during combustion or detonation may be present.
As long as this DTC is active, the engine power is limited and the EGR system is deactivated. The fault code cannot be cleared while the fault is present.
Elimination:
If there is any trouble code related to the fuel metering inlet valve, first replace it.
Then check the supply pressure as described in L6 of document 03: 14-01, edition 2. Continue diagnostics on the “troubleshooting tree” Lc if the pressure is too high. Otherwise, replace the fuel metering inlet valve.
Check supply pressure, fuel metering inlet valve, high pressure pump and check for leaks. Check diffuser o-rings in high pressure pump.

Pressure in the fuel supply system
Fault:
The pressure in the fuel line significantly exceeds the set value. The reasons:
The probable cause of the malfunction is a defect in the bypass valve. It is also possible that the drain line is clogged.
Notes:
A fault code will be recorded only if the pressure in the fuel line exceeds the set value for 7 seconds or a longer time interval. This time period was set to avoid writing code due to short-term pressure fluctuations not caused by functional deviation.
If the signal voltage is outside the acceptable range, the control unit uses the preprogrammed value.
With this fault, the engine torque is reduced by 30% while the fault code is active (confirmed). As a result of this malfunction, uneven engine operation and increased smoke can occur.

In the case of engines with EGR, the engine works with EGR, but without any feedback through the mass flow sensor. Therefore, the control unit will only control the composition of EGR gases roughly, “roughly”, using predefined values ??to set the position of the EGR valve. Calibration of the mass flow sensor is turned off.

Title:
Exhaust gas temperature sensor in front of the SCR catalytic converter Fault:
Invalid signal from the sensor. The constant value of the signal. The reasons:
The temperature sensor in front of the catalytic converter SCR is faulty. Notes:
A malfunction leads to a lack of reagent supply or the addition of a very small amount of reagent.
The fault affects the emission of nitrogen oxides (NOx) by the car, and a warning lamp lights up in the instrument cluster, warning of a high level of pollutants. On vehicles with NOx control, a text message is also displayed.
Cars with NOx control
An active DTC limits the maximum engine torque to approximately 40%.
An active DTC cannot be deleted from the control unit. When the malfunction is resolved so that the malfunction code becomes inactive, the control unit must ensure that the malfunction has been eliminated.
Elimination:
Check exhaust gas temperature sensor and wiring.
Use the following options to ensure that the problem is resolved:
To verify that the malfunction has been rectified, perform the “Recognizing DTCs for NOx Control Invalidations” check, which is located on the “Checks” tab in SDP3. This test should be performed outdoors, because the exhaust gas temperature becomes very high and there is a risk that the exhaust hose will melt.
Performing this check may take from 5 to 30 minutes, depending on which DTCs are active. Otherwise, follow these steps to make the control unit invalidate the fault.
Start the engine and verify that the engine speed is above 1000 rpm and that the SCR system starts. Repeat this four times in a row. If the temperature is below -8 ° C or the reagent is frozen, the SCR system will not start.
If the fault is resolved, the fault code becomes inactive. Clear the fault code.
You can go to the fault code monitoring function and view the fault code. There you can see if the conditions under which the control unit confirms that the fault has been eliminated have been satisfied. When conditions are satisfied and a check is performed, the status of the DTC is displayed during the check process. If the DTC is under review, the control unit has detected a fault. If the fault is resolved, the fault code becomes inactive and can be erased.
Using the ignition key, turn off and turn on the power three times in a row at intervals of 10 seconds to deactivate the test lamp.

Also check for DTCs related to CAN communication in other control units. Troubleshoot these problems first. Check the wiring and clean the connectors.
If this does not help, check whether the SCR control unit and the NOx sensor are receiving an on / off voltage (U15) signal simultaneously. If the above action does not help, replace the NOx sensor first, and if that does not work, replace the SCR control unit. However, it is not typical for the fault to be covered in the SCR control unit. Before replacing the SCR control unit, make sure that the fault is not caused by something else.
Continue as follows to ensure that the problem is resolved:
Turn off and turn on the onboard power supply with the ignition key.
If the fault is resolved, the fault code becomes inactive. Clear the fault code.
Using the ignition key, turn off and turn on the power three times in a row at intervals of 10 seconds to deactivate the test lamp.

Title:
Communication with the SCR control unit Fault:
CAN MSG8 message “NOx sensor data before catalytic converter” (NOx sensor data before catalytic converter) is not received from NOx sensor. If the vehicle configuration is configured for an SCR system, this message is received via the SCR control unit.
The reasons:
The data exchange between the engine control unit and the NOx sensor in front of the catalytic converter was interrupted.
On vehicles with the SCR system, this message is sent via the SCR control unit. If a 100C fault code was generated at the same time, there may be a communication failure between the engine control unit and the SCR control unit. See fault code description 100C.
If the vehicle is equipped with an SCR system and the DTC 10C was not generated simultaneously, there may be a communication failure between the SCR control unit and the NOx sensor in front of the catalytic converter.
If the DTC was generated only once, it may be due to the interruption of the voltage supply to the NOx sensor while maintaining the voltage supply to the SCR control unit. If this DTC is generated frequently, it may be due to wiring problems or loose connectors.
Notes:
No description Elimination:
Clear the DTC memory and try to start the engine.
Turn off and turn on the onboard power supply with the ignition key several times. If the DTC is generated again, check the wiring and clean the electrical connectors.
If the fault code is still generated, make sure that both the SCR control unit and the NOx sensor in front of the catalytic converter receive voltage through terminal U15 simultaneously.
If the fault is not detected, first replace the NOx sensor for the catalytic converter and then the SCR control unit (if equipped with the car).

Title:
NOx sensor Fault:
Problem with CAN bus communication with NOx sensor in front of the catalytic converter. The reasons:
The malfunction may be caused by the loss of power supply to the NOx sensor and the simultaneous power supply to the SCR control unit.
If the fault recurs frequently, there is probably a fault in the connectors or the wiring. Notes:
Malfunction adversely affects engine emissions of nitric oxide. The control lamp is on.
On engines with a NOx control system, torque is reduced by 40%. The fault code cannot be cleared while the fault is present. When the malfunction is resolved, the control unit must verify this in order for the fault code to become inactive.
Elimination:
Check the wiring and clean the connectors. Ensure that power is simultaneously supplied to the SCR control unit and the NOx sensor.
If this does not help, first replace the NOx sensor, and if that does not help, replace the SCR control unit. To verify that the problem is resolved, follow these steps:
Switch off the ignition with the key, wait 90 seconds and then turn it on again. If the fault is resolved, the fault code becomes inactive. Clear the fault code.

Title:
Communication with the SCR control unit Fault:
The engine control unit does not receive a CAN message from the NOx sensor. If the vehicle is equipped with an SCR system, the CAN message is transmitted via the SCR control unit.
The reasons:
Communication between engine control unit and SCR control unit interrupted.
If there are several faults, the SCR control unit shuts down the SCR system to prevent damage. This means that communication between the SCR control unit and the engine control unit has been lost.
If this DTC is generated alone and there are no other DTCs of the SCR system, this may be due to the interruption of the supply voltage to the SCR control unit while simultaneously supplying voltage to the engine control unit.
The SCR control unit in the pump may be faulty.
If a fault code is generated frequently, it may be due to a problem in the wiring harness or connectors. If fault code 5688 was generated at the same time, there may be a fault in the engine control unit.
If this DTC was generated, and DTC 5688 is not, it is possible that there is a fault in the wiring. Notes:
As a result of a fault, the injection of the reagent is turned off.
Fault codes are generated based on information from the SCR control unit. If there is no communication between the SCR control unit and the engine control unit, no SCR related fault codes are generated in the engine control unit.
If this DTC is generated, there is no communication between the engine control unit and the SCR control unit. This may imply that there are no SCRs related to the SCR in the engine control unit, and those that have been erased will not be generated again, even if there is still a fault.
The fault affects the emission of nitrogen oxides (NOx) by the car, and a warning lamp lights up in the instrument cluster, warning of a high level of pollutants. On vehicles with NOx control, a text message is also displayed.

SCR reagent pressure Fault:
The reagent pressure at start-up drops by more than 0.5 bar. The reasons:
The vent valve is stuck open or there are leaks in the reagent hose. Notes:
The SCR system is turned off until the next cycle of motion begins (ignition is switched off with the key) and any reagent is injected, which leads to an increase in the level of discharge. When the system is turned off, fault codes 100C, 100A and 100B (CAN time exceeded) can be generated. Be sure to troubleshoot this problem before taking action on codes 100C, 100A, and 100B.
Note: Diagnostics regarding this DTC cannot be performed while the SCR system is off. Therefore, this DTC cannot become passive or be generated again (if deleted) before the next cycle of motion. In order to be able to read the fault codes, turn off the ignition with the key for 90 seconds and then turn it on again.
Elimination:
Check whether the vent valve is open in the open position. Check reagent hose for leaks. EMS 4129

An active DTC limits the maximum engine torque to approximately 40%.
An active DTC cannot be deleted from the control unit. When the malfunction is resolved so that the malfunction code becomes inactive, the control unit must ensure that the malfunction has been eliminated.
Elimination:
Make sure the hose is not twisted.
Check whether reagent crystals are present in the reagent dispenser or main unit. Wash off the crystals with water.
If the temperature was below -10 ° C, check to see if the injection valve in the reagent dispenser is leaking.
Follow the verification system as provided in SDP3 for the SCR system. System checks can help detect some of the faults listed above.
Continue as follows to ensure that the problem is resolved:
To ensure that the problem has been rectified, you can check the “Recognizing DTCs for NOx Control Invalid”, which is on the “Checks” tab in SDP3. This test should be performed outdoors because the exhaust gas temperature becomes very high and there is a risk that the exhaust gas hose will melt. Performing this check may take from 5 to 30 minutes, depending on which DTCs are active.
Otherwise, you can take the following steps so that the control unit recognizes the fault as invalid.
Verify that the SCR system is running four times in sequence. Switch off the ignition with the key at intervals of 90 seconds between cycles.
If the fault is resolved, the fault code becomes inactive. Clear the fault code.
You can click on the DTC monitoring function and view the DTC. There you can see if the conditions under which the control unit confirms that the fault has been eliminated have been satisfied. When conditions are satisfied and a check is performed, the status of the DTC is displayed during the check process. If the DTC is under review, the control unit has detected a fault. If the fault is resolved, the fault code becomes inactive and can be erased.
To turn off the alarm, turn off and turn on the ignition with the ignition key three times in a row at 10-second intervals.

Voltage supply for SCR control unit Fault:
The SCR control unit turns off too soon. The power to the SCR system was turned off before the system was turned off.
The reasons:
If the car has a mass switch (used in buses and ADR cars), a fault code can be generated if the battery mass switch is used within 90 seconds after the ignition is turned off.
There may be a fault in the supply voltage to the SCR system.
In addition, the malfunction may be due to an internal malfunction in the control unit.
If at the same time a fault code 5657 is generated, the fault is probably not in the SCR system. Notes:
Full system shutdown will not be performed. It takes approximately 90 seconds to turn off the SCR system after the ignition key is turned off.
This means that a reagent will remain in the hoses and in the nozzle dispenser.
This can cause the system to freeze in cold weather, which is likely to cause damage to the SCR system.
Elimination:
Switch off the ignition with the key, wait 90 seconds and then turn it on again. If the DTC remains inactive, delete the DTC.

An active DTC limits the maximum engine torque to approximately 40%.
An active DTC cannot be deleted from the control unit. When the malfunction is resolved so that the malfunction code becomes inactive, the control unit must ensure that the malfunction has been eliminated.
Elimination:
Check exhaust gas temperature sensor and wiring. Check exhaust system.
Use the following options to ensure that the problem is resolved:
To verify that the malfunction has been rectified, perform the “Recognizing DTCs for NOx Control Invalidations” check, which is located on the “Checks” tab in SDP3. This test should be performed outdoors, because the exhaust gas temperature becomes very high and there is a risk that the exhaust hose will melt.
Performing this check may take from 5 to 30 minutes, depending on which DTCs are active. Otherwise, follow these steps to make the control unit invalidate the fault.
Start the engine and verify that the engine speed is above 1000 rpm and that the SCR system starts. Repeat this four times in a row. If the temperature is below -8 ° C or the reagent is frozen, the SCR system will not start. If the fault is resolved, the fault code becomes inactive. Clear the fault code.
You can go to the fault code monitoring function and view the fault code. There you can see if the conditions under which the control unit confirms that the fault has been eliminated have been satisfied. When conditions are satisfied and a check is performed , the status of the DTC is displayed during the check process. If the DTC is under review, the control unit has detected a fault. If the fault is resolved, the fault code becomes inactive and can be erased.

unit for the starter is incorrect. Notes:
Shutting off the fuel in the absence of a signal from one of the engine speed sensors. Elimination:
If the engine crankshaft rotates when the starter is activated, check the speed sensors, connectors and wiring.
If the engine crankshaft does not rotate when the starter is activated, check the proper performance of the latter. EMS 4352

Title:
Crankshaft speed signals Fault:
When the engine is running, the signals from the two speed sensors do not match. The reasons:
If fault code 4352 was registered and fault code 4608 is not, this may be due to the fact that the electrical wiring going to one of the engine crankshaft speed sensors is confused. The control unit cannot determine which.
If, however, both DTC 4352 and DTC 4608 were registered, this may be due to the fact that the engine took a few turns in the opposite direction.
If, when you try to start the engine, fault codes 4352 and 4608 are generated, this may be due to the fact that the engine speed sensors were interchanged.
Notes:
If DTC 4352 was registered and DTC 4608 is not, as long as a fault is present, the maximum engine torque is reduced by 30%. Increased engine speed at idle will also be lower than usual.
If both crankshaft speed sensors are faulty, the engine will shut down. Elimination:
Check sensors, connectors and wiring.

Title:
Fuel pressure in the accumulator Fault:
The fuel pressure in the pressure accumulator exceeded the maximum permissible value. The reasons:
Possible reasons:
Feed pressure too high.
Fuel metering inlet valve sticking or leaking. Faulty diffuser in high pressure pump.
Notes:
At low loads, abnormally high noise generated during combustion may be present.
As long as this DTC is active, the engine power is limited and the EGR system is deactivated. The fault code cannot be cleared while the fault is present.
Elimination:
The pressure in the fuel system reaches a very high value, up to 3000 bar.
Before starting any work, release pressure in the fuel system. When handling the system, it should be assumed that it is under pressure, even if the engine is off.
Wear protective gloves and goggles.
Additional information about the rules of safe handling of the fuel system is given in the service instructions, section “Fuel System XPI”.
If there is any trouble code related to the fuel metering inlet valve, first replace it.
Then check the supply pressure as described in L6 of document 03: 14-01, edition 2. Continue with the Lc “troubleshooting tree” if the pressure is too high. Otherwise, replace the fuel metering inlet valve.
If the operating time since the generation of the fault code exceeds 10 hours, empty the EGR cooler, as there is a danger of condensation in the air-cooled EGR cooler after the EGR system is turned off. Empty the EGR cooler following the instructions given in the manual for service stations, subgroup 01-65.

Title:
Charge air pressure sensor Fault:
The charge air pressure and atmospheric pressure differ when the engine is idling. The reasons:
Possible reasons:
Malfunction of the charge air pressure sensor or atmospheric pressure sensor.
Malfunction of coolant temperature sensor, charge air temperature sensor, fuel line pressure sensor or fan speed sensor.
The fault may also be in the connectors or electrical wiring circuits. Notes:
The charge air pressure sensor, the coolant temperature sensor, the charge air temperature sensor, the fuel line pressure sensor and the fan speed sensor have a common power supply. In the event of a fault in one of the sensors, it may affect the electrical circuits of the other sensors.
Elimination:
Make sure that the charge air pressure and the atmospheric pressure are about the same value, approximately 1 bar of absolute pressure, with the engine off or when the engine is idling.
Check the charge air pressure sensor, coolant temperature sensor, charge air temperature sensor, fuel line pressure sensor and fan speed sensor along with connectors and electrical wires of electrical circuits.
Check whether the charge air pressure sensor is covered with soot. If so, clean it.
If a fault in the charge air pressure sensor is not detected, troubleshoot the atmospheric pressure sensor using a coordinator.

Title:
Crankshaft speed signals Fault:
The speed signal from the engine crankshaft speed sensor is lower than it should be for the current crankshaft speed.
The reasons:
A malfunction may be due to an excessively large distance between the engine speed sensor and the flywheel. In addition, it may be due to a problem in the wiring or connectors.
Notes:
The control unit increases the sensitivity of the sensor so that a fault code is not generated. Therefore, a fault code will not be generated again even if the fault still persists. This increase in sensor sensitivity may lead to the generation of other trouble codes. These DTCs can be ignored. The automatic adjustment performed by the control unit does not in any way affect the operation of the control unit.
The fault does not affect the operation of the engine, i.e. There is no power limit. Elimination:
If the DTC was generated greater than in the two cases, check the distance between the sensor and the flywheel (which is allowed a maximum of 1.5 mm).

Fault in the electrical wiring or in the nozzle of the cylinder number 7. Perhaps the fault is a short circuit in one or more of the solenoid valves or in the electrical wiring.
Notes:
Fault occurs only when the engine is running. The control unit tries to constantly use the nozzles, regardless of the presence of faults.
Elimination:
Disconnect the wiring from the control unit and from the solenoid valve on the faulty injectors. Measure the resistance of the solenoid valve.
Measure the resistance between the positive or negative connection of the solenoid valve and the cylinder block. An infinite resistance value (8 ohms) must be obtained.
Check the wiring pin connections to the control unit and the braid wiring in the cylinder head.
Measure the resistance between the ground wire or power wire and the cylinder block. An infinite resistance value (8 ohms) must be obtained.
Connect the engine control unit wiring and measure the resistance between the power wire or ground wire and the control unit’s mass point. An infinite resistance value (8 ohms) must be obtained.
If the operating time since the generation of the fault code exceeds 10 hours, empty the EGR cooler, as there is a danger of condensation in the air-cooled EGR cooler after the EGR system is turned off. Empty the EGR cooler following the instructions given in the manual for service stations, subgroup 01-65.

Title:
Failed mass flow sensor adaptation Fault:
The engine control unit calculates that more air enters the engine than is measured by the T126 mass flow sensor.
During the adaptation of the mass flow sensor, the highest possible permissible value is obtained, which can be adapted at one operating point.
The reasons:
Possible causes of a malfunction can be the following:
leaks in the EGR system or in the charge air system mass flow sensor T126 gives incorrect readings
wrong values ??from the back pressure sensor in the exhaust system T125, charge air pressure sensor T122 or charge air temperature sensor T121
Notes:
The engine control unit uses information from the mass flow sensor to regulate the EGR content and to calculate the ratio of air and fuel. The calculation is also performed taking into account the engine speed, the amount of fuel injected and the signals from the backpressure sensor in the exhaust system, the charge air pressure sensor and the charge air temperature sensor. The calculated amount of air is compared with the signal from the mass flow sensor at certain predetermined engine speeds (operating points). The adaptation of the mass flow sensor is performed in such a way that the calculated value coincides with the measured value at these engine speeds.
Adaptation occurs continuously throughout the work. During adaptation, the EGR valve closes temporarily. Adaptation occurs every hour.
If there is a leak in the EGR system or the charge-air system, or in the event of a failure of any of the sensors, the adaptation of the mass flow sensor may fail. If the difference between the calculated and measured mass flow rate is more than 30%, the adaptation will reach its minimum or maximum allowable value and a fault code will be generated.
The engine control unit turns off the EGR system and the engine power decreases. The fault code cannot be cleared while the fault is present.
Elimination:
Check for leaks in the EGR system or in the charge-air system. Perform an “EGR check for leaks” in SDP3, if available.
Check the mass flow sensor T126, the back pressure sensor in the exhaust system T125, the charge pressure sensor T122 or the charge temperature sensor T121.
Check the connectors and electrical wiring.
After diagnostics and repair, always perform the “EGR check for invalidation of malfunction codes” if this malfunction code has been generated. This check can be performed using SDP3.
If the DTC persists after checking, it is likely that the repair was performed incorrectly or the software in the engine control unit is out of date. With SDP3 / VERA, make sure the car engine software is updated to the latest version. If the software is old, program the EMS as a spare part.
If the operating time since the generation of the fault code exceeds 10 hours, empty the EGR cooler, as there is a danger of condensation in the air-cooled EGR cooler after the EGR system is turned off. Empty the EGR cooler following the instructions given in the manual for service stations, subgroup 01-65.

Crankshaft speed signals
Fault:
When the engine is running, the signals from the two speed sensors do not match. The reasons:
If fault code 4608 was registered and fault code 4352 was not, this may be due to the fact that the electrical wiring going to one of the engine crankshaft speed sensors is confused. The control unit cannot determine which. If, however, both DTC 4608 and DTC 4352 were registered, this may be due to the fact that the engine took a few turns in the opposite direction, for example, if the engine stalled while moving uphill.
If, when you try to start the engine, fault codes 4608 and 4352 are generated, this may be due to the fact that the crankshaft speed sensors of the engine were interchanged.
Notes:
If DTC 4608 was registered and DTC 4352 is not, as long as a fault is present, the maximum engine torque is reduced by 30%. Increased engine speed at idle will also be lower than usual.

Title:
Crankshaft speed signals Fault:
The speed signal from the engine crankshaft speed sensor is lower than it should be for the current crankshaft speed.
The reasons:
A malfunction may be due to an excessively large distance between the engine speed sensor and the flywheel. In addition, it may be due to a problem in the wiring or connectors.
Notes:
The control unit increases the sensitivity of the sensor so that a fault code is not generated. Therefore, a fault code will not be generated again even if the fault still persists. This increase in sensor sensitivity may lead to the generation of other trouble codes. These DTCs can be ignored. The automatic adjustment performed by the control unit does not in any way affect the operation of the control unit.
The fault does not affect the operation of the engine, i.e. There is no power limit.
Elimination:
If the DTC was generated in more than two cases, check the distance between the sensor and the flywheel (a maximum of 1.5 mm is allowed).

Pump nozzle cylinder 2 Fault:
Too fast increase of current in the coil of the solenoid valve pump-nozzle. The reasons:
The fault may be due to a too low resistance of the solenoid valve.
If fault code 4643 was generated at the same time, it is possible that this is a consequence of a short circuit in the solenoid valve or electrical wiring. In addition, it is possible that a short circuit has occurred between the valve cover and one of the terminals on the solenoid valve.
Notes:
The engine control unit is programmed in such a way that if any faults occur in individual cylinders that are not critical, these cylinders will continue to work. In the case of some types of short circuits, the work of several cylinders is disrupted at once. Fault codes will be recorded for all cylinders operating with violations.
If fault codes were generated for two or more cylinders, the maximum engine torque will be reduced by 30%. Elimination:
Check the electrical components, electrical connectors and wiring.
Check the resistance of the coil of the solenoid valve. Electrical resistance should be equal to 0.4-0.6 ohms. Also check the resistance between the solenoid valve connector and the motor. If the resistance is less than 100 ohms, there may be a short circuit.

The fault may be due to a too low resistance of the solenoid valve.
If at the same time a malfunction code 4707 was generated, it is possible that this is a consequence of a short circuit in the solenoid valve or electrical wiring. In addition, it is possible that a short circuit has occurred between the valve cover and one of the terminals on the solenoid valve.
Notes:
The engine control unit is programmed in such a way that if any faults occur in individual cylinders that are not critical, these cylinders will continue to work. In the case of some types of short circuits, the work of several cylinders is disrupted at once. Fault codes will be recorded for all cylinders operating with violations.
If fault codes were generated for two or more cylinders, the maximum engine torque will be reduced by 30%. Elimination:
Check the electrical components, electrical connectors and wiring.
Check the resistance of the coil of the solenoid valve. Electrical resistance should be equal to 0.4-0.6 ohms. Also check the resistance between the solenoid valve connector and the motor. If the resistance is less than 100 ohms, there may be a short circuit.
Clear the trouble code memory.
If there is a malfunction, replace the injector pump first and then the control unit. EMS 4705

Fuel shutoff valve Fault:
When the engine is stopped by turning off the fuel shut off valve, the fuel pressure in the low pressure line drops very slowly.
The reasons:
Possible reasons:
Fuel shut-off valve stuck open.
If a malfunction code 4752 or 4753 was also generated, there may be a short circuit in the electrical circuit. Otherwise, either the fuel shut-off valve or the fuel supply pressure sensor is faulty.
Malfunction in the electrical circuit of the charge air pressure sensor, charge air temperature sensor, coolant temperature sensor or fan speed sensor.
Since the DTC is generated when the engine is turned off, it can only be deleted after the engine has been successfully turned off.
Notes:
The pressure sensor in the fuel line, the coolant temperature sensor, the charge air pressure sensor, the charge air temperature sensor and the fan speed sensor have a common power supply. In the event of a fault in one of the sensors, it may affect the electrical circuits of the other sensors.
When the engine is turned off with the ignition key, the solenoid valves will continue to try to keep the engine running, while the fuel shut-off solenoid valve sends a signal to turn off the engine. If this fails, i.e. the pressure in the fuel line will not decrease, a malfunction code is generated, after which the engine is turned off by the electromagnetic valves.
A fault code is generated only in the case of three consecutive failed attempts to turn off the engine. While the fault is active, the maximum engine torque is reduced by 30%.
Since the DTC is generated when the engine is turned off, it can only be deleted after the engine has been successfully turned off.
Elimination:
Check whether DTC 4752 or 4753 was generated. If so, check the fuel shut-off valve and the wiring.
If DTC 4752 or 4753 was not generated, first replace the fuel shut-off valve and then, if necessary, the pressure sensor in the fuel line.

Title:
Fuel supply to cylinders Fault:
The torque developed by the front group of cylinders (cylinders 1-3) significantly exceeds the torque developed by the rear group of cylinders (cylinders 4-6).
The reasons:
One of the fuel control or solenoid injection timing solenoid valves does not work correctly. In this case, the torque developed by one of the two groups of cylinders does not correspond to the specified value. This may be due to the fact that an excess amount of fuel enters the front group cylinders or too little fuel enters the rear group cylinders.
If the engine is gaining momentum, the front-group cylinder fuel control solenoid valve is stuck in a position where too much fuel flows into the cylinders.
If the engine is slowing down, the rear cylinder fuel control solenoid valve is stuck in a position where there is too little fuel in the cylinders.
If the engine drops speed and white smoke appears with the exhaust gases, then the solenoid valve controlling the injection timing of the rear group of cylinders lets in insufficient amount of fuel. Fuel injection starts so late that the fuel cannot ignite.
A malfunction may also be caused by leakage of the sealing rings on the pump nozzles. Notes:
Uneven engine performance due to engine speed limiting at 500 … 550 rpm. The fuel shut-off solenoid valve is faulty.
Elimination:
If the engine starts to gain momentum, then replace the front cylinder group fuel control solenoid valve. If the engine slows down, replace the rear cylinder fuel control solenoid valve.
If the engine has lost momentum and white smoke has appeared with the exhaust gases, then replace the solenoid valve controlling the advance angle of injection of the rear group of cylinders.
If you suspect a leak in the pump nozzles, replace all o-rings. EMS 4759

When the engine is running, the signals from the two speed sensors do not match. The reasons:
If fault code 4865 was registered, and fault code 4881 was not, this may be due to the fact that the electrical wiring going to one of the engine crankshaft speed sensors is confused.
The control unit cannot determine which.
If, however, both fault code 4865 and fault code 4881 were registered, this may be due to the fact that the engine took a few turns in the opposite direction. The fault code becomes inactive when the engine stops rotating in the opposite direction.
If when you try to start the engine, fault codes 4865 and 4881 are generated, this may be due to the fact that the crankshaft speed sensors of the engine were interchanged.
Notes:
If DTC 4865 has been registered, and DTC 4881 is not, as long as the fault is present, the maximum engine torque is reduced by 30%.
Increased engine speed at idle will also be lower than usual. Elimination:

EGR valve with a pneumatic cylinder control Fault:
When an EGR valve receives a request to go to the closed position, the EGR valve position sensor T124 indicates an open position (> 8%) affecting engine performance (power and emissions).
The reasons:
The EGR valve could not close completely.
Spring return fault on the EGR valve control cylinder. A problem with the operation of the valve block, V107.
The EGR Position Sensor T124 is faulty or disconnected from the circuit. Notes:
After starting the engine, the engine control unit performs an active check on the EGR valve if the following conditions are met:
The engine runs at idle.
Engine temperature above 60 ° C.
There is no request to turn on the EGR system (0%). Motor brake is not included.
EGR has been adapted.
The air pressure in the parking brake circuit is at a normal level (above 7.5 bar).
In the case of a DTC, the EGR system remains active and the engine power does not decrease. A fault code can be cleared even if it is active.
Elimination:
Check:
EGR valve control cylinder by activating the EGR valve using SDP3. Set the set point to 0% and make sure that the EGR position sensor T124 reports a position close to zero. If an EGR adaptation was performed, the position should be below 1%. If the position does not fall below 8%, a fault code is generated. If the position is close to 8% or above this value, this is the cause of the DTC.
EGR valve control cylinder, connectors and wiring to EGR valve position sensor circuit T124. Functioning valve block V107.
If the EGR valve position sensor T124 is faulty or disconnected from the circuit.

Possible causes of the DTC may be as follows:
The EGR valve shut-off element does not open. This can be caused by sticking of the valve itself, insufficient pressure of compressed air supplied to the executive cylinder or leakage of compressed air from the executive cylinder.
Track valve may be faulty.
The movable element of the diffuser stuck in the open position. EGR gas leakage.
The mass flow sensor may indicate a too high value, as a result forcing the engine control unit to conclude that the engine is receiving too few EGR gases.
Notes:
The fault affects the emission of nitrogen oxides (NOx) by the car, and a warning lamp lights up in the instrument cluster, warning of a high level of pollutants. On vehicles with NOx control, a text message is also displayed.
Cars with NOx control
An active DTC cannot be deleted from the control unit. When the malfunction is resolved so that the malfunction code becomes inactive, the control unit must ensure that the malfunction has been eliminated.
Elimination:
Check the throttle in the EGR valve, control cylinder and follow valve by activating the elements with SDP3. Check wedge diffuser.
Check for leaks in the EGR system. Check the air flow sensor.
After elimination of malfunction with the help of SDP3, it is necessary to restore the initial parameters of the EGR system in the control unit.
Continue as follows to ensure that the problem is resolved:
Drive the car for at least 10 minutes to get the EGR system running. The EGR system must be running so that the control unit can verify the repair.
If the fault is resolved, the fault code becomes inactive. In this case, delete the fault code.

System shutdown Fault:
Incorrect procedure to turn off the engine control unit. Power line 30 was disconnected from the control unit earlier than line 15, that is, the power from the battery was interrupted before the ignition was turned off.
The reasons:
The power to the engine control unit was turned off prematurely.
This could be due to an incorrect engine stopping procedure with the ignition key or the engine being stopped using the ground switch.
The supply voltage can be interrupted if additional equipment is connected to the consumer. Notes:
When checking in engine kill mode, the control unit performs a functional check of the components after the ignition is turned off.
If the car is equipped with the SCR system, then at a stop, the system hoses are cleaned. It is important that the SCR system can be stopped without interrupting the power supply. Otherwise, the SCR system may be damaged:
the reducing agent in the hoses will freeze and the nozzles will be clogged.
With this fault, the engine torque is reduced by 30% while the fault code is active (confirmed). This fault also leads to a longer engine start.
It is assumed that the malfunction is resolved as soon as the engine control unit successfully completes a kill test. An active DTC cannot be cleared until successful testing in the kill mode.
Elimination:
Always turn off the engine with the ignition key.
If the car has an SCR system, the main battery switch should not be turned off until at least 1.5 minutes have passed after turning off the key.
Make sure that there is no additional equipment that interferes with the power supply. EMS 5658

Malfunction of the electrical circuit of the fuel temperature sensor or electrical circuit of the oil pressure sensor. Notes:
The mass flow sensor, oil pressure sensor and fuel temperature sensor have a common power supply. In the event of a fault in one of the sensors, it may affect the electrical circuits of the other sensors.
A malfunction occurs because the mass flow sensor is not working. The engine will work with EGR, but without feedback on the signal of the mass flow sensor. Therefore, the control unit will only control the composition of EGR gases roughly, “roughly”, using predefined values ??to set the position of the EGR valve.
Calibration of the mass flow sensor is turned off.
Malfunction affects vehicle emissions of nitrogen oxides (NOx); on the instrument cluster a warning lamp lights up, warning of a high level of pollutants. Vehicles with a NOx control system also display a text message.

Variable geometry turbocharger, mechanical failure Fault:
The engine control unit has detected that the mechanism is not moving properly, with the result that the correct charge air pressure cannot be achieved.
The reasons:
Sticking of mechanical elements in a variable geometry turbocharger. This may be due, for example, to the presence of deposits, icing or damage to the guide vanes.
Notes:
The engine control unit turns off the EGR system and the engine power decreases. The fault code cannot be cleared while the fault is present.
The time for confirming the DTC is 1 s, the time for invalidation is 1 s. Elimination:
Check the mechanical components of the turbocharger by checking the state of the variable geometry turbocharger in SDP3. Mechanical damage can be detected already at room temperature. Jamming due to mechanical tolerances or deposits can be detected when the turbocharger has a high operating temperature. Therefore, it is also necessary to perform a check on a heated turbocharger. The heated turbocharger has a temperature above 300 ° C (the exhaust gas temperature in the turbocharger can reach 600 ° C). Measure the temperature of the turbine housing using a non-contact infrared thermometer.
If the result of the status check is unsatisfactory:
Remove the actuator. Make sure that the lever with the toothed segment can move freely between its extreme positions when moved by hand.
If the lever with the toothed segment can move freely: Replace the actuator. Reinstall the actuator using SDP3 and perform a turbocharger status check with variable geometry.
If the reset or status check fails, replace the actuator.
If the status check is successful, it is possible that the previous adaptation of the actuator was incorrect. No replacement is required.
If the lever with the toothed segment cannot move freely: replace the turbocharger with a variable geometry.
If the status check is successfully passed for both the warm-up and the cold turbocharger, the cause of the DTC is a temporary malfunction, for example, as a result of icing when starting in low temperature conditions.
If the operating time since the generation of the fault code exceeds 10 hours, empty the EGR cooler, as there is a danger of condensation in the air-cooled EGR cooler after the EGR system is turned off.

Title:
Variable geometry turbocharger, danger of overspeeding Fault:
Indication of exceeding the allowable rotational speed of a variable geometry turbocharger. The reasons:
Excessive speeds could be caused by a combination of a number of factors: for example, the width of the annular gap in the nozzle of a turbocharger with variable geometry, the position of the EGR valve and the amount of fuel supplied. The annular gap of the nozzle and the EGR valve is likely to be fully or partially closed at the same time, since there is a high engine load at the time of the malfunction.
Turbine speed is measured by a turbine speed sensor. However, at the same time, the charge air pressure sensor checks the accuracy of the rotational speed. A fault code is generated if the difference between the actual and the estimated speed is too large. The fault may be present either in the turbine speed sensor or in the charge air pressure sensor.
Notes:
To reduce the turbine speed, the engine control unit immediately reduces engine power. Engine power will remain low until the turbine speed is sufficiently reduced.
The time for confirming the malfunction code is 30 s, the acknowledgment time is 5 s. Elimination:
Check the installation and operation of the turbine speed sensor T120.
Measure the resistance at the turbocharger T120 speed sensor at room temperature. The resistance between pins 1 and 2 should be 850 ohms ± 50 ohms.
Make sure the air filter is not blocked.
Ensure that the charge air lines are not clogged and do not leak. Check the installation and operation of the charge air pressure sensor.
Check if any other DTCs are generated. Take the necessary actions to eliminate the causes of other fault codes for the EGR system, fuel system or variable geometry turbocharger that were active.

Variable Geometry Turbocharger, timeout in the CAN bus Fault:
The rupture of the communication circuit between the engine control unit and the turbocharger actuator with variable geometry. DTC, if not received a certain number of consecutive CAN messages.
The reasons:
Constant or repeated gap in the CAN circuits between the engine control unit and the actuator. Permanent faults are often caused by faults in the electrical wiring harness, connector or engine control unit. Repeated malfunctions are often caused by scratching the wires on the connector.
Notes:
The engine control unit turns off the EGR system and the engine power decreases. The fault code cannot be cleared while the fault is present.

Check whether DTC 1686 has also been generated. If so, run diagnostics for this DTC. If not, see instructions below.
Ensure that the connector on the actuator harness is healthy and clean and that there is no moisture in it. Replace the connector if it is damaged.
Disconnect the connector between the actuator and the engine wiring harness.
Measure the resistance between pin 3 and pin 4 in the actuator connector at room temperature. Resistance should be either 120 ohms ± 10 ohms or 2,600 ohms ± 50 ohms. If the resistance does not match the specified values, replace the actuator.
Measure the resistance between pin 3 and pin 4 in the engine wiring harness connector at room temperature. Resistance should be 120 ohms ± 10 ohms.
If the resistance does not match the stipulated values:
Disconnect the connector from the engine control unit. Measure the resistance in the cable harness between pin 3 and pin A4_6 at room temperature. Resistance should be 5 ohms ± 4 ohms. Repeat the measurement for pin 4 and pin A4_7. Measure between the individual wires of the wiring harness to eliminate any short circuit in the wiring harness. Measure the resistance between the A4_6 pin and A4_7 pin in the engine control unit at room temperature. Resistance should be 120 ohms ± 10 ohms.
If all of the above measurements gave the correct values, the waiting time on the CAN bus is probably due to friction between the pin and the cylindrical contact in the connector. This type of rubbing is difficult to detect without advanced electronic equipment. Replace the actuator and the connector and the opposite connector in the engine wiring harness. Securely fasten the wiring harness and its connectors.

Check for leaks between the main unit and the reagent dispenser. If there are no leaks, replace the main unit. The
presence of a malfunction in the main unit is not typical. Before replacing the main unit, make sure that the fault was not caused by something else.
Follow the verification system as provided in SDP3 for the SCR system. System checks can help detect some of the faults listed above.
Continue as follows to ensure that the problem is resolved:
There should be no active DTCs for air pressure in the SCR system, for faults in the main unit, for blocking the injection device, or for a temperature sensor downstream of the catalytic converter. Nor should there be an active DTC for leaks in the SCR system.
To ensure that the problem has been rectified, you can check the “Recognizing DTCs for NOx Control Invalid”, which is on the “Checks” tab in SDP3. This test should be performed outdoors, because the exhaust gas temperature becomes very high and there is a risk that the exhaust hose will melt. Performing this check may take from 5 to 30 minutes, depending on which DTCs are active.
Otherwise, you can take the following steps so that the control unit recognizes the fault as invalid.
Start the engine and verify that the engine speed is above 1000 rpm and that the SCR system starts. Perform a road test of 15 minutes on the road. If the temperature is below -8 ° C or the reagent is frozen, the SCR system will not start.

Causes of failure may be the following:
Malfunction in the SCR power supply circuit.
Internal malfunction in the control unit of the exhaust gas reduction system.
If the DTC was generated in conjunction with DTC 5657, the reason probably lies outside the SCR system. Notes:
The SCR system will not shut down correctly if the control unit is turned off too early. The reagent will still remain in the injection hoses and injectors. At low temperatures there is a risk of damage to the SCR system from ice formation in the hoses.

Voltage supply for SCR control unit Fault:
The SCR control unit turns off too soon. The power to the SCR system was turned off before the system was turned off.
The reasons:
If the car has a mass switch (used in buses and ADR cars), a fault code can be generated if the battery mass switch is used within 90 seconds after the ignition is turned off.
There may be a fault in the supply voltage to the SCR system.
In addition, the malfunction may be due to an internal malfunction in the control unit.
If at the same time a fault code 5657 is generated, the fault is probably not in the SCR system. Notes:
Full system shutdown will not be performed. It takes approximately 90 seconds to turn off the SCR system after the ignition key is turned off.
This means that a reagent will remain in the hoses and in the nozzle dispenser.
This can cause the system to freeze in cold weather, which is likely to cause damage to the SCR system. Elimination:

Title:
Communication with the SCR control unit Fault:
The engine control unit does not receive a CAN message from the NOx sensor. If the vehicle is equipped with an SCR system, the CAN message is transmitted via the SCR control unit.
The reasons:
Communication between the engine control unit and the SCR control unit or between the SCR control unit and the NOx sensor is interrupted.
If fault code 5688 was simultaneously generated, there may be a problem in the communication between the engine control unit and the SCR control unit.
If fault code 5688 was simultaneously generated, there may be a communication failure between the SCR control unit and the NOx sensor.
If the DTC was generated only once, it may be due to the interruption of the voltage supply to the NOx sensor while maintaining the voltage supply to the SCR control unit.
The SCR control unit in the main unit may be faulty.
If a fault code is generated frequently, it may be due to a problem in the wiring harness or connectors. Notes:
As a result of a fault, the injection of the reagent is turned off.
Fault codes are generated based on information from the SCR control unit. If there is no communication between the SCR control unit and the engine control unit, no SCR related fault codes are generated in the engine control unit.
If this DTC is generated, there is no communication between the engine control unit and the SCR control unit. This may imply that there are no SCRs related to the SCR in the engine control unit, and those that have been erased will not be generated again, even if there is still a fault.
Elimination:
Also check for DTCs related to CAN communication in other control units. Troubleshoot these problems first. Switch off the ignition and wait for 90 seconds before turning it on again.
If there are fault codes for the SCR system, first diagnose them.
Switch the ignition on and off several times. Fault codes that were not generated in the engine control unit could be present in the SCR control unit, because this fault code is active.
If the DTC recurs and the DTC does not indicate that the SCR system is off, check the wiring and fuses for the SCR system and clean the electrical connectors.
Also make sure that both control units simultaneously receive voltage (U15).
If the steps above do not help, replace the SCR control unit. If this does not help, replace the engine control unit. EMS 43361

The engine control unit has no CAN message from the NOx sensor. If the vehicle is equipped with an SCR system, the CAN message is transmitted via the SCR control unit.
The reasons:
Communication between the engine control unit and the NOx sensor or between the SCR control unit and the NOx sensor is interrupted.
If a DTC 43345 was generated at the same time, there may be a problem in the communication between the engine control unit and the SCR control unit.
Troubleshoot using fault code 43345. If fault code 43345 was not generated at the same time, there may be a fault in the communication between the SCR control unit and the NOx sensor.
If the DTC was generated only once, it may be due to the interruption of the voltage supply to the NOx sensor while maintaining the voltage supply to the SCR control unit.
The SCR control unit in the pump may be faulty.
If a fault code is generated frequently, it may be due to a problem in the wiring harness or connectors. Notes:
Functions in the SCR system are not affected. Elimination:
Clear the DTC memory and check the engine start.
Turn off and turn on the onboard power supply with the ignition key. If the DTC reappears, check the wiring and clean the electrical connectors.
If this does not help, check whether the SCR control unit and the NOx sensor are receiving an ignition voltage on
/ off signal (U15) at the same time. If the above action does not help, replace the NOx sensor first, and if that does not work, replace the SCR control unit. However, it is not typical for the fault to be covered in the SCR control unit. Before replacing the SCR control unit, make sure that the fault is not caused by something else. EMS 43362

If the vehicle is equipped with an SCR system, the CAN message is transmitted via the SCR control unit.
The reasons:
Communication between engine control unit and NOx sensor interrupted.
If a malfunction code A951 was generated at the same time, there may be a problem in the communication between the engine control unit and the SCR control unit. Troubleshoot by fault code A951.
If the DTC A951 was not generated at the same time, there may be a fault in the communication between the SCR control unit and the NOx sensor.
If the DTC was generated only once, it may be due to the interruption of the voltage supply to the NOx sensor while maintaining the voltage supply to the SCR control unit.
If this DTC is generated frequently, it may be due to wiring problems or loose connectors. Notes:

The fault may be due to a too low resistance of the solenoid valve.
If a malfunction code 49155 was generated at the same time, it is possible that this is a consequence of a short circuit in the solenoid valve or the wiring. In addition, it is possible that a short circuit has occurred between the valve cover and one of the terminals on the solenoid valve.
Notes:
The engine control unit is programmed in such a way that if any faults occur in individual cylinders that are not critical, these cylinders will continue to work. In the case of some types of short circuits, the work of several cylinders is disrupted at once. Fault codes will be recorded for all cylinders operating with violations.
If fault codes were generated for two or more cylinders, the maximum engine torque will be reduced by 30%. Elimination:
Check the electrical components, electrical connectors and wiring.

The coordinator was unable to save information about the new key. The fault may also be due to the fact that the engine check was not confirmed in the coordinator.
Notes:
Starter locked. If the vehicle speed exceeds 20 km / h, the engine speed drops to 500 rpm until the DTC is active.
If the vehicle speed is below 20 km / h, the fuel supply is interrupted, the engine is turned off and cannot be started until the DTC is active.
Elimination:
It is only necessary to delete the fault code if no fault codes were generated in the coordinator and the driver did not notice any faults. If any trouble codes are recorded in the coordinator’s memory, start troubleshooting.
After completing the troubleshooting, erase the trouble code from the engine control unit. Ensure that this error code is no longer generated during operation.

Pump nozzle cylinder 5 Fault:
Too fast increase of current in the coil of the solenoid valve pump-nozzle. The reasons:
The fault may be due to a too low resistance of the solenoid valve.
If at the same time a malfunction code 50179 was generated, it is possible that this is a consequence of a short circuit in the solenoid valve or wiring. In addition, it is possible that a short circuit has occurred between the valve cover and one of the terminals on the solenoid valve.
Notes:
The engine control unit is programmed in such a way that if any faults occur in individual cylinders that are not critical, these cylinders will continue to work. In the case of some types of short circuits, the work of several cylinders is disrupted at once. Fault codes will be recorded for all cylinders operating with violations.
If fault codes were generated for two or more cylinders, the maximum engine torque will be reduced by 30%. Elimination:
Check the electrical components, electrical connectors and wiring.
Check the resistance of the coil of the solenoid valve. Electrical resistance should be equal to 0.4-0.6 ohms. Also check the resistance between the solenoid valve connector and the motor. If the resistance is less than 100 ohms, there may be a short circuit.

Title:
Pressure in the fuel supply system Fault:
The pressure in the fuel line is well below the set value. The reasons:
Possible causes of failure:
One of the two relief valves opens at too low a pressure. The fuel shut-off solenoid valve remains closed.
The fuel filter is clogged.
Air in the fuel or lack of fuel in the tank. Malfunctioning booster pump.
Significant fuel leak from the system. Notes:
A fault code will only be generated if the supply pressure is below the allowable pressure for at least 7 seconds. This time period was set to avoid writing code due to short-term pressure fluctuations not caused by functional
deviation.
If the signal voltage is outside the acceptable range, the control unit uses the preprogrammed value. With this fault, the engine torque is reduced by 30% while the fault code is active (confirmed).
Elimination:
Check for fuel in the tank and bleed the fuel system to remove air from it. Check the opening pressure of both relief valves.
Check the position of the fuel shut-off solenoid valve. Check the condition of the fuel filter.
Check the fuel priming pump.
Check the tightness of the fuel system.
If a malfunction has appeared while the car is coasting (when the car is going to descend with the accelerator pedal fully released), then you can use the “Stored operational data” engine parameters stored in the memory to analyze the fault. See “Feed Pressure” section. If the pressure deviation in the fuel line for a specified time interval is -1.0 bar or more, then the fuel filter may be clogged. If there is no significant pressure deviation in the fuel line, then this may be due to jamming of the bypass valve in the open position.

Fuel shutoff valve Fault:
When the engine is stopped by turning off the fuel shut off valve, the fuel pressure in the low pressure line drops very slowly.

Fuel shut-off valve stuck open.
If a malfunction code of 55040 or 55041 was also generated, there may be a short circuit in the electrical circuit. Otherwise, either the fuel shut-off valve or the fuel supply pressure sensor is faulty.
Notes:
When the engine is turned off with the ignition key, the solenoid valves will continue to try to keep the engine running, while the fuel shut-off solenoid valve sends a signal to turn off the engine. If this fails, i.e. the pressure in the fuel line will not decrease, a malfunction code is generated, after which the engine is turned off by the electromagnetic valves.
The fault code is generated only in the case of three consecutive failed attempts to shut down. While the fault is active, the maximum engine torque is reduced by 30%.
Since the DTC is generated when the engine is turned off, it can only be deleted after the engine has been successfully turned off.
Please note that the oil pressure sensor, fuel temperature sensor and mass flow sensor have a common power supply. In the event of a fault in one of the sensors, it may affect the electrical circuits of the other sensors.

The torque developed by the front group of cylinders (cylinders 1-3) significantly exceeds the torque developed by the rear group of cylinders (cylinders 4-6).
The reasons:
A malfunction may be due to a failure of one of the fuel supply solenoid valves or an injection advance, which causes an incorrect engine torque for one row of cylinders. This may be due to the following reasons:
One of the front row solenoid valves of the cylinders supplying too much fuel (too high torque) to cylinders 1-3. One of the solenoid valves in the rear row of cylinders that supplies too little fuel (too low torque) to cylinders 4-6.
If the engine produces a higher power than usual, immediately before the malfunction code is generated, one of the front row solenoid valves may be faulty.
If the engine produces a lower power than usual, immediately before the malfunction code is generated, one of the solenoid valves in the back row of cylinders may be faulty.
A fault code can also be generated even if there is no fault in any of the solenoid valves. In some cases, the DTC is caused by faulty pump injectors or fluctuations in the transmission caused by driving conditions.
Notes:
Engine may operate unevenly.
To protect the engine, the maximum engine torque is reduced by 30%.
To generate a DTC, the fault must be present for 6 seconds. If the fault disappears, after three seconds the engine will return to normal operation.
Elimination:

The reasons:
One of the fuel control or solenoid injection timing solenoid valves does not work correctly. In this case, the torque developed by one of the two groups of cylinders does not correspond to the specified value.This may be due to the fact that an excess amount of fuel enters the front group cylinders or too little fuel enters the rear group cylinders.

where too much fuel flows into the cylinders.
If the engine is slowing down, the rear cylinder fuel control solenoid valve is stuck in a position where there is too little fuel in the cylinders.
If the engine drops speed and white smoke appears with the exhaust gases, then the solenoid valve for controlling the injection timing of the rear cylinder group lets in insufficient amount of fuel. Fuel injection starts so late that the fuel can not be ignited.
A malfunction may also be caused by leakage of the sealing rings on the pump nozzles. Notes:

Title:
Mutual verification between the engine control unit and the coordinator Fault:
Mutual verification between the engine control unit and the coordinator failed. The reasons:
The engine control unit is not associated with the coordinator. Notes:
As long as the DTC is present, the engine cannot be started. The starter is blocked and the fuel supply is turned off.
Elimination:
It is only necessary to delete the fault code if no fault codes were generated in the coordinator and the driver did not notice any faults. If any trouble codes are recorded in the coordinator’s memory, start troubleshooting.
After completing the troubleshooting, erase the trouble code from the engine control unit. Ensure that this error
code is no longer generated during operation.
