This document is the official PACCAR engine related DTC diagnostic procedure from the Electrical System Service Manual, covering DTCs generated when the Engine Control Module databus message is not received by the CECU. Published by PACCAR for cab systems in 2011 and newer trucks, it provides technicians with step-by-step troubleshooting methods using the Electronic Service Analyst (ESA) diagnostic tool.
The guide addresses simultaneous engine-related component failures caused by V-CAN (J1939) communication loss between the Engine Control Module and the CECU, helping mechanics quickly identify whether faults stem from communication breakdown or individual sensor issues.
