PCM/SKREEM Programming

NOTE: Before replacing the PCM, be sure to check the related component/circuit integrity for failures not detected due to a double fault in the circuit. Most PCM 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) and the Sentry Key Remote Entry Module (SKREEM) are replaced at the same time, perform the following steps:
1. Using the DRB III(R) scan tool, follow the on screen instructions to program the new PCM.
2. Using the DRB III(R), follow the on screen instructions to program the new Sentry Key Remote Entry Module.
3. Replace all ignition keys and program them to the new Sentry Key Remote Entry Module.
