Normal Operation
The instrument cluster receives the door ajar status from the vehicle security module over the UBP communication network, circuit 693 (OG). When any of the doors are ajar, the door ajar switch will close, completing a ground signal to the vehicle security module. The vehicle security module receives the door ajar status from the hardwired door ajar switches. The liftgate ajar switch input is hardwired to the vehicle security module in series through circuit 700 (WH/VT) and the liftgate glass ajar switch, circuit 1351 (TN). The door ajar switches are hardwired to the vehicle security module through circuit 761 (GY/RD) (RF), 760 (PK/LB) (RR), 759 (LG/YE) (LR), and 765 (YE/BK) (LF). All of the door ajar switches are grounded through circuit 1205 (BK).
