Pcm/SKREEM Programming: Notes

WARNING: This page is about a different car, the 2006 Dodge Magnum, 2006 Dodge Charger, and 2006 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Before replacing the Powertrain Control Module (PCM), be certain 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. 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 Diagnostic Trouble Code (DTC) has been set.

NOTE: After a SKREEM/WCM is replaced, the ignition/transponder keys need to be programmed to the new SKREEM/WCM. Follow the directions on the diagnostic scan tool. The transponder key for the SKREES/SKIM and the RKE will both be programmed during this operation. There is no need to program the fob of the key for RKE functionality once the transponder key is programmed to the new SKREEM/WCM.

NOTE: When a PCM and the SKREEM/WCM are replaced at the same time, perform the following steps in order:

Program the new PCM.
Program the new SKREEM/WCM.
Program all ignition/transponder keys to the new SKREEM/WCM.
