Circuit/System Description
The automatic door lock feature can be programmed to control the door lock system. The automatic door lock 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 driver door switch, passenger door switch and body control module (BCM) will lock the vehicle doors when the ignition 1 input is ACTIVE, the door jam switch inputs are INACTIVE and the transaxle is not in PARK.
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 driver door module, passenger door module and BCM will lock all doors again.
Once the automatic door lock feature has locked the doors, the BCM will then unlock all the doors when the transaxle is shifted into PARK.
