Charging System - Generators & Regulators: Programming: Pcm/SKREEM
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:
- Using the DRB III(R) scan tool, follow the on screen instructions to program the new PCM.
- Using the DRB III(R), follow the on screen instructions to program the new Sentry Key Remote Entry Module.
- Replace all ignition keys and program them to the new Sentry Key Remote Entry Module.
