U0002–CAN C BUS OFF PERFORMANCE - ESM

For a complete wiring diagramRefer to Section 8W

Theory of Operation

Some controllers communicate with other controllers over the CAN C bus. The Shift Lever Assembly (SLA) contains a Electronic Shift Module (ESM) that continuously monitors the bus activity and receives the messages it needs. The CAN C bus is also used to communicate transmission MIL status to the Engine Controller.

Refer to 8-ELECTRICAL/ELECTRONIC CONTROL MODULES - DIAGNOSIS AND TESTING for diagnostic procedures and for further possible causes.
