VIN Checksum Error
VIN CHECKSUM ERRORWHEN MONITORED
With the ignition on.
SET CONDITION
Once the Instrument Cluster learns a valid VIN and another valid VIN is transmitted on the bus. The Instrument Cluster decodes the VIN that is transmitted on the bus by the PCM. If the VIN is valid the Instrument Cluster stores the information. If the VIN information does not equate to the encrypted value then the fault is set.
POSSIBLE CAUSES
- Powertrain control module
1. POWERTRAIN CONTROL MODULE
NOTE:
- The V.I.N. is embedded into the Instrument Cluster memory during production and can not be modified. Do not attempt to "swap" a cluster from one vehicle to another.
- This code will only be set if the PCM has been exchanged or "swapped" into this vehicle from another.
If any components have been exchanged or "swapped", reinstall the original parts.
With the DRBIII(R), erase DTCs.
Cycle the ignition.
With the DRBIII(R), read DTCs.
If this code resets, view repair.
Repair
