EEPROM Programming

EEPROM Programming Note

The replacement ECM comes pre-programmed with vehicle software/calibrations. However, the new ECM must be programmed with the frequency code of the Theft Deterrent Module currently on the vehicle. Refer to Antitheft and Alarm Systems under Accessories and Optional Equipment for the proper procedure. The vehicle will not start until this procedure is performed.
