Circuit/System Verification

  1. With a scan tool, verify that any module which stores the vehicle VIN matches the actual vehicle VIN:
    • 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.
  2. If all modules VIN match, replace the TDM.
