Standard Procedure - Pcm/Skim Programming: Notes
WARNING: This page is about a different car, the 2003 Dodge Intrepid, 2003 Chrysler Intrepid, 2003 Chrysler Concorde, and 2003 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Before replacing the PCM for a failed driver, control circuit or ground circuit, be sure to check the related component/circuit integrity for failures not detected due to a double fault in the circuit. Most PCM driver/control circuit failures are caused by internal component failures (i.e. relay 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 set.
When a PCM (SBEC) and the SKIM are replaced at the same time perform the following steps in order:
- Program the new PCM (SBEC)
- Program the new SKIM
- Replace all ignition keys and program them to the new SKIM.
