Standard Procedure - Pcm/Skim Programming: Notes

WARNING: This page is about a different car, the 2004 Jeep Wrangler. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: ASSURE THE DRBIII(R) IS PROGRAMMED WITH THE LATEST VERSION OF CURRENT SOFTWARE.
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. 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 PCM (JTEC) and the SKIM are replaced at the same time, perform the following steps in order:

  1. Program the new PCM (JTEC).
  2. Program the new SKIM.
  3. Replace all ignition keys and program them to the new SKIM.
