Circuit/System Verification
- With a scan tool, verify the stored VIN in the following modules matches the actual vehicle VIN:
- IPC
- XBCM
- DDM
- PDM
- If any modules stored VIN does not match the actual VIN, perform the setup procedure for that module. If the stored VIN does not match after setup, replace the module.
- If all modules VIN match, replace the TDM.
