PCM/ECM/SKIM Programming

The SKIS Secret Key is an ID code that is unique to each SKIM. This code is programmed and stored in the SKIM, PCM and transponder chip (ignition
keys). When replacing the PCM it is necessary to program the secret key into the new PCM using the scan tool. Perform the following steps to program the secret key into the PCM.
1. Turn the ignition switch on (transmission in park/neutral).
2. Use the scan tool and select THEFT ALARM, SKIM then MISCELLANEOUS.
3. Select PCM REPLACED (GAS ENGINE).
4. Enter secured access mode by entering the vehicle four-digit PIN.
5. Select ENTER to update PCM VIN.

NOTE: If three attempts are made to enter 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).

6. Press ENTER to transfer the secret key (the SKIM will send the secret key to the PCM).
7. Press Page Back to get to the Select System menu and select ENGINE, MISCELLANEOUS, and SRI MEMORY CHECK.
8. The scan tool will ask, Is odometer reading between XX and XX? Select the YES or NO button on the scan tool. If NO is selected, the scan tool will read, Enter odometer Reading . Enter the odometer reading from the Instrument Panel and press ENTER.
