Powertrain Control Module: Service and Repair
Programming the Powertrain Control Module
PROGRAMMING THE POWERTRAIN CONTROL MODULE
IMPORTANT NOTE: Before replacing the PCM for a failed driver, control circuit or ground circuit, be sure to check the related
component/circuit integrity for failures not detected due to a double fault in the circuit. Most PCM driver/control circuit failures are caused by
internal failure to components (i.e. 12-volt pull-ups, drivers and ground sensors). These failures are difficult to detect when a double fault has
occurred and only one DTC has set.
NOTE: IF THE PCM AND THE 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.
The SKIS "Secret Key" is an ID code that is unique to each SKIS. This code is programmed and stored in the SKIM, engine controller and
transponder ship (ignition key). When replacing the PCM it is necessary to program the secret key into the PCM.
1. Turn the ignition ON (transmission in Park/Neutral).
2. Use the DRB and select "THEFT ALARM", "SKIM", then "MISCELLANEOUS".
3. Select "PCM REPLACED".
4. Enter secured access mode by entering the vehicle four-digit PIN.
NOTE: IF THREE ATTEMPTS ARE MADE TO ENTER THE SECURE ACCESS MODE USING AN INCORRECT PIN, SECURED
ACCESS MODE WILL BE LOCKED OUT FOR ONE HOUR. TO EXIT THIS LOCKOUT MODE, TURN THE IGNITION TO THE RUN
POSITION FOR ONE HOUR THEN ENTER THE CORRECT PIN. (ENSURE ALL ACCESSORIES ARE TURNED OFF. ALSO
MONITOR THE BATTERY STATE AND CONNECT A BATTERY CHARGER IF NECESSARY).
5. Press "ENTER" to transfer the secret key (the SKIM will send the secret key to the PCM).
