NOTE:
Before replacing the Powertrain Control Module (PCM) or Engine Control Module (ECM), be certain to check the related component/circuit integrity for failures not detected due to a double fault in the circuit. Most PCM/ECM driver/control circuit failures are caused by internal component failures (such as relays and solenoids) and shorted circuits (such as pull-ups, drivers, and switched circuits). These failures are difficult to detect when a double fault has occurred and only one DTC has been set.
When a PCM, or ECM, and the Sentry Key Remote Entry Module (SKREEM) on vehicles equipped with the Sentry Key Immobilizer System (SKIS) are replaced at the same time, perform the following steps in order:
- Program the new PCM or ECM.
- Program the new SKREEM (also known as the Wireless Control Module/WCM).
- Replace all ignition keys and program them into the new SKREEM/WCM.
