U1411-IMPLAUSIBLE FUEL VOLUME SIGNAL RECEIVED
For a complete wiring diagram Refer to Section 8W.
- When Monitored:
Ignition on.
- Set Condition:
The fuel volume message the PCM is receiving is implausible. The circuit is continuously monitored.
| Possible Causes |
| CAN C OPEN OR SHORTED |
| BODY CONTROL MODULE |
| PCM |
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING).
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 DTCIgnition 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.
- Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
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 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - DIAGNOSIS AND TESTING) for the appropriate diagnostic procedures.
- Perform BODY VERIFICATION TEST – VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES/FRONT CONTROL MODULE - DIAGNOSIS AND TESTING)
No
- Replace and program the Powertrain Control Module per Service Information.
- Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
