PASSLOCK - Reprogramming Auto Learn

PASSLOCK Reprogramming Auto Learn

Important: Due to component variability, the vehicle theft deterrent (VTD) system must have the learn procedure performed regardless, if the vehicle starts on the first ignition cycle after a VTD repair.

You must perform a theft relearn procedure if any of the following components have been replaced:

- Passlock� sensor
- Body control module (BCM)
- Powertrain control module (PCM)

The above modules, with the exception for the Passlock� Sensor must also be programmed with each module's own vehicle configuration. See the individual module service manual section.

Time required, approximately 10 minutes.

1. Insure that the battery is fully charged.
2. Use the scan tool in order to clear the DTCs.
3. Turn the ignition switch from the OFF position to the CRANK position attempting to start the vehicle. The vehicle will start and then stall.
4. Leave the ignition switch in the ON position while observing the security indicator.
5. When the security indicator turns off, which can take up to 10 minutes, turn the ignition switch off. Wait 10 seconds.
6. The BCM and the PCM will learn the new code on the next start attempt.
