Powertrain Control Module: 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 Sentry Key Immobilizer Module (SKIM), "Secret Key" data must also be updated to enable engine starting. See SENTRY KEY IMMOBILIZER Module under PROGRAMMING in
BODY CONTROL MODULES - CONCORDE, INTREPID, LHS & 300M article.
