Powertrain Control Module: Notes
2002 Chrysler 300M BaseSECTION Notes
NOTE:
If Powertrain Control Module (PCM) has been replaced, the correct vehicle mileage and Vehicle Identification Number (VIN) must be programmed into replacement PCM to prevent DTCs from being set in Anti-Lock Brake System (ABS) Controller Anti-Lock Brake (CAB) and Occupant Restraint Controller (ORC). If replacing Powertrain Control Module (PCM) on models equipped with a Smart Key Immobilizer Module (SKIM), secret key data must also be updated to enable engine starting. To program PCM, see POWERTRAIN CONTROL MODULE
under PROGRAMMING.
