| List of Diagnostic Trouble Codes | |||
| J1939 Code | Code Description | Troubleshooting Procedure | ATA Code |
| Diagnostics Exist that Require J1939 Service Tool Connection | This code indicates that Cat ET is not communicating on the J1939 data link. Cat ET must be communicating on the J1939 data link and the ATA data link in order to fully service the engine. Refer to Troubleshooting, “Electronic Service Tools” for additional information on establishing communication on both data links.
Establish communication with both data links in order to view the J1939 equivalent of the 154-14 code. |
