For a complete wiring diagram, refer to appropriate SYSTEM WIRING DIAGRAMS article.
- When Monitored:
Ignition on.
- Set Condition:
The odometer message the PCM is receiving is implausible. The circuit is continuously monitored.
| Possible Causes |
|---|
| CAN B OPEN OR SHORTED |
| CLUSTER MODULE |
| FRONT CONTROL MODULE |
| PCM |
Always perform the PRE-DIAGNOSTIC TROUBLESHOOTING PROCEDURE before proceeding.
Theory of Operation
The Front Control Module isn't receiving an odometer signal over CAN B from the Cluster Module. The FCM has to send the PCM an odometer signal over CAN C. The signal the FCM is sending over CAN C is implausible.
