Door Ajar Indicator Description and Operation

Door Ajar Indicator System Components

The door ajar indicator system consists of the following components:

Driver and Passenger Door Ajar Operation

The body control module (BCM) receives a discrete input from the respective door latch to indicate the status of the door. The BCM then communicates this status to the instrument panel cluster (IPC) via a serial data message. The IPC, upon receipt of this serial data message, will illuminate the appropriate ajar message in the driver information center (DIC) and also send a serial data 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 km/h (5 mph).
