Door Ajar Indicator Description and Operation

Door Ajar Indicator System Components

The door ajar indicator system consists of the following components:

•	The body control module (BCM)

•	The instrument panel cluster (IPC)

•	The driver information centre (DIC)

•	The driver door jamb switch

•	The passenger door jamb switch

•	The left rear door jamb switch

•	The right rear door jamb switch

•	The tailgate actuator/ajar switch

Driver and Passenger Door Ajar Operation

The body control module (BCM) receives a discrete input from the respective jamb switch to indicate the status of the door. The BCM then communicates this status to the instrument panel cluster (IPC) via a class 2 message. The IPC, upon receipt of this class 2 message, will illuminate the appropriate ajar message in the driver information centre (DIC) and also send a class 2 message to the radio to activate the door ajar audible warning when the following conditions are met:

•	The transmission is removed from PARK.

•	The vehicle speed is greater then 8.05 km/h (5 mph).

Gate Ajar Operation

The instrument panel cluster (IPC) illuminates the GATE AJAR indicator when the body control module (BCM) detects that the tailgate or liftglass is ajar or open. The IPC receives a LAN message from the BCM requesting illumination. If the vehicle is in the forward or reverse gear position, the BCM activates an audible warning.
