Door/Trunk Ajar Indicator/Lamp: Description and Operation
Door Ajar Indicator Description and Operation
The instrument panel cluster (IPC) and the driver information display (DID) in the radio illuminate the door ajar indicator when the body control module
(BCM) detects that any of the four doors is open. The IPC and DID receive a low speed GMLAN serial data message from the BCM requesting
illumination. If the vehicle is shifted out of park with a door open, the BCM sends a low speed GMLAN serial data message to the IPC in order to
activate an audible warning.
