U1411

U1411-IMPLAUSIBLE FUEL VOLUME SIGNAL RECEIVED





For a complete wiring diagram refer to Diagrams/Electrical. Electrical Diagrams

- 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 BCM has to send the PCM a fuel volume signal over CAN C. The signal the BCM sends over CAN C is implausible.

Diagnostic Test

1. ACTIVE DTC

Ignition on, engine not running.

With a scan tool read DTCs.

Is the DTC active at this time?

Yes

- Go To 2

No

- Refer to the INTERMITTENT CONDITION Diagnostic Procedure. Intermittent Condition
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test

2. CAN C BUS DTCS ALSO ACTIVE

With a scan tool check for DTCs in the BCM.

Are any CAN C related DTCs active at this time?

Yes

- Refer to Communications for the appropriate diagnostic procedures.
- Perform BODY VERIFICATION TEST. Body Verification Test

No

- Replace and program the Powertrain Control Module.
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test
