DAF LF, CF, XF Truck ABS, ABS-D, ABS-E, ASR, ASR-E, ASR-D, SDS-3 Fault Codes List

Service technicians have no problem recognising breakdowns and carrying out machine diagnostics, DAF LF, CF, XF Truck ABS, ABS-D, ABS-E, ASR, ASR-E, ASR-D, SDS-3 Fault Codes List, plus they are familiar with equipment from a variety of manufacturers.

Anti-lock brake systems (ABS) – generally also referred to as anti-lock systems (ALS) – are designed to prevent the vehicle wheels from locking as a result of the service brake being applied with too much force, especially on slippery road surfaces. The idea is to maintain cornering forces on braked wheels to ensure that the vehicle or vehicle combination retains its driving stability and manoeuvrability as far as physically possible. Anti-Slip Regulation (ASR) – Increasing the engine output (accelerating) on a slippery road surface can easily lead to the maximum adhesion on one or all powered wheels being exceeded causing them to spin, especially if the vehicle is unladen or partially laden. Spinning wheels when driving off or accelerating represent a safety risk just like locked wheel do when braking.
