Programming Powertrain Control Module: Notes

CAUTION: Assure the DRBIII® 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.
