VIN Mismatch

VIN MISMATCH

Theory of Operation

When powered, the Occupant Restraint Controller (ORC) monitors the BUS for a broadcast message containing the Vehicle Identification Number (VIN) by the Powertrain Control Module (PCM).

- When Monitored:
With the ignition on.

- Set Condition:
The Powertrain Control Module (PCM) broadcasts the current VIN on the Bus. The Occupant Restraint Controller (ORC) will set this DTC if the VIN message is missing or the VIN stored in the OCM does not match the current VIN.
