Powertrain Control Module (PCM) Replacement: Notes

WARNING: This page is about a different variant/trim than selected.

Service of the powertrain control module (PCM) should consist of either replacement of the PCM, or programming of the electrically erasable programmable read only memory (EEPROM). If the diagnostic procedures call for the PCM to be replaced, the replacement PCM should be checked to ensure that the correct part is being used. If the correct part is being used, remove the faulty PCM and install the new service PCM.
