PCM/ECM REPROGRAMMING - GAS

MODULE REPROGRAMING


Replacement PCM's will require programming utilizing the StarSCAN(R) or equivalent. The PCM will not operate the engine until it is programmed. A Diagnostic Trouble Code (DTC) will be set - "not programmed".



CAUTION: Extreme care must be taken when programming a calibration into a generic PCM. Do not randomly select a calibration. Once a calibration is selected and programmed, the controller cannot be reprogrammed to a different calibration. The module can only be reprogrammed to a more recent version of that calibration.

SPECIAL TOOLS/EQUIPMENT OR EQUIVALENT REQUIRED:









**REPAIR PROCEDURE - USING THE INTERNET TO RETRIEVE THE FLASH FILE:


NOTE: The StarSCAN(R) or equivalent diagnostic scan tool fully supports Internet connectivity.
