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.
