U1411-IMPLAUSIBLE FUEL VOLUME SIGNAL RECEIVED





For a complete wiring diagram Consult Diagrams/Electrical.

- When Monitored:
Ignition on.

- Set Condition:
The fuel volume message the PCM is receiving is implausible. The circuit is continuously monitored. One Trip fault.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Initial Inspection and Diagnostic Overview.

Theory of Operation

The Front Control Module isn't receiving a fuel volume signal over CAN B from the Cluster Module. The FCM has to send the PCM a fuel volume signal over CAN C. The signal the FCM sends over CAN C is implausible.
