U1411-IMPLAUSIBLE FUEL VOLUME SIGNAL RECEIVED

For a complete wiring diagram refer to Diagrams/Electrical.

- When Monitored:

Ignition on.

- Set Condition:

The fuel volume message the PCM is receiving is implausible. The circuit is continuously monitored.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.

Theory of Operation

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