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 liftgate actuator/ajar switch
Gate Ajar Operation
The body control module (BCM) receives a discrete input from the liftgate ajar switch to indicate the status of the liftgate. The BCM then communicates
this status to the instrument panel cluster (IPC) via GMLAN serial data. The IPC, upon receipt of this message, will illuminate the gate ajar message in
the driver information center (DIC) and also send a GMLAN serial data message to the radio to activate the gate 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).
