Programmable Automatic Door Locks - Manual Transmission

WARNING: This page is about a different car, the 2002 GMC Sierra, 2002 GMC Cab & Chassis Sierra, 2002 Chevrolet Silverado, and 2002 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.

The automatic door lock feature can be programmed to control the door lock system. The automatic door lock feature is factory programmed to have no doors lock or unlock. For detailed instructions on programming the automatic door locks, refer to VEHICLE PERSONALIZATION .

When the automatic door lock feature is programmed to control the door lock system, the BCM will lock the vehicle doors if the following inputs are true:

Ignition 1 input is active.
All door jamb switch inputs are inactive.
Vehicle speed is greater than 24 km/h (15 mph) for 2 seconds.

This automatic door lock function will only occur once per ignition cycle unless a door jamb switch input changes state to active and back to inactive. Then the BCM will lock all doors again.

Once the automatic door lock feature has locked the doors, the BCM will the unlock all the doors once the ignition key is removed from the ignition.
