Powertrain Control Module: Notes

NOTE: If the PCM and the Sentry Key Immobilizer Module (SKIM) are replaced at the same time, program the VIN into the PCM first. All vehicle keys will then need to be replaced and programmed to the new SKIM. See SENTRY KEY IMMOBILIZER MODULE  .
NOTE: The Sentry Key Immobilizer System (SKIS) secret key data is an identification code that is unique to each SKIS. This code is programmed and stored in the PCM, SKIM and ignition key transponder chip. When replacing the PCM it is necessary to program the secret key data into the PCM.
NOTE: PCM and the Transmission Control Module (TCM) are incorporated into one control module. After replacing PCM, reprogram pinion factor and perform shift quality quick learn procedure. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION.
