DTC B2976
Circuit / System Description
The body control module (BCM) receives a discrete input from ajar switches within driver and passenger door latches. 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 ajar icon in the driver information center (DIC) and also send a serial data massage to the radio to activate the door ajar audible warning when the engine has been started and the gear selector is moved from the P (park) position.
The door ajar switches supply a ground to the BCM when the door is open. Once the door is closed the door ajar switch opens removing the ground to the BCM. The BCM sends a signal to the IPC to illuminate the door ajar indicator when a door is open.
