Door Ajar Indicator Description and OperationDoor 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 center (DIC)
^ The driver door jamb switch
^ The passenger door jamb 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 center (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).
