RAM 1500 Truck 4WD V8-5.7L VIN D (2005)
Engine Control Module: Service and Repair
PCM/ECM/SKIM Programming
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 (i.e. relays and solenoids) and shorted circuits (i.e. 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 Powertrain Control Module (PCM) for a gasoline engine, or a Engine Control Module for a diesel engine and the Sentry Key Immobilizer
Module (SKIM) on vehicles equipped with the Sentry Key Immobilizer System (SKIS) are replaced at the same time, perform the following steps in
order:
1. Program the new PCM/ECM.
2. Program the new SKIM.
3. Replace all ignition keys and program them into the new SKIM.
