Pcm/SKREEM Programming: Notes

WARNING: This page is about a different car, the 2005 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
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 Diagnostic Trouble Code (DTC) has been set.

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

  1. Program the new PCM.
  2. Program the new SKREEM.
  3. Replace all ignition keys and program them to the new SKREEM.
