Programmable Automatic Door Locks

WARNING: This page is about a different car, the 2016 GMC Acadia, 2016 Chevrolet Traverse, and 2016 Buick Enclave. 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 feature is factory programmed to have all doors lock and unlock.

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

Ignition 1 input is active
Each door ajar switch input indicates their doors are closed
Transmission is shifted out of PARK

This automatic door lock function will only occur once per ignition cycle, unless a door ajar switch input changes state to active and back to inactive. Then the BCM will lock the rear doors and send a serial data message to the door lock/window switches command their latches to lock again.

BCM will unlock the rear doors and send a serial data message to the door lock/window switches command their latches to unlock when the transmission is shifted into PARK.
