Test H: The Door Ajar Warning Indicator Is Never/Always On
PINPOINT TEST H: THE DOOR AJAR WARNING INDICATOR IS NEVER/ALWAYS ONH1-H4:
Normal Operation
On vehicles not equipped with remote keyless entry (RKE), the instrument cluster receives the door ajar status from the RH and LH front door ajar switches through hardwired circuitry. The LH front door ajar switch is hardwired through circuit 344 (BK/YE) and the RH front door ajar switch is hardwired through circuit 345 (BK/PK). The door ajar switches are grounded through circuit 57 (BK). When either of the doors are open or ajar, the door ajar switch closes, completing a ground circuit and signaling the instrument cluster of the door ajar status.
On vehicles equipped with RKE, the instrument cluster receives the door ajar status from the vehicle security module (VSM) over the communication network.
