PCM/ECM Reprogramming

The SKIS Secret Key is an ID code that is unique to each SKIM. This code is programmed and stored in the SKIM, the PCM, and the ignition key transponder chip(s). When replacing the PCM, it is necessary to program the secret key into the new PCM using the DRBIII(R) scan tool. Perform the following steps to program the secret key into the PCM.
1. Turn the ignition switch to the On position (transmission in Park/Neutral).
2. Use the DRBIII(R) 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 secured access mode using an incorrect PIN, secured access mode will be locked out for one hour. To exit this lockout mode, turn the ignition switch to the ON 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 DRBIII(R) will ask, Is odometer reading between XX and XX? Select the YES or NO button on the DRBIII(R). If NO is selected, the DRBIII(R) will read, Enter Odometer Reading (From I.P. odometer) . Enter the odometer reading from the instrument cluster and press ENTER.
