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 center (DIC)
- The driver door jamb switch
- The passenger door jamb switch
- The left rear door jamb switch
- The right rear door jamb switch
- The liftgate 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 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 (5mph).
