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 SKREEM 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 SKREEM.
The SKREES Secret Key is an I.D. code that is unique to each SKREES. This code is programmed and stored in the SKREEM, engine controller and
transponder chip (ignition key). When replacing the PCM it is necessary to program the secret key into the PCM.
NOTE: After replacing the PCM, you must reprogram pinion factor.
1. Turn the ignition on (transmission in park/ neutral).
2. Use the DRBIII(R) and select THEFT ALARM, SKREEM 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 SKREEM will send the secret key to the PCM).
