With the ignition on.

- Set Condition:
The current VIN message from the PCM is different than the VIN stored in the BCM.

2. OTHER CAN C MODULES SET VIN MISMATCH
1. Turn the ignition on.
2. With the scan tool, read DTCs.

Is the VIN Mismatch DTC set in other CAN C modules?

Yes

- Replace the PCM. Powertrain Control Module - Removal.
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test.

No
