SWITCH, Door Ajar

DOOR

DOOR

This vehicle has one door ajar switch for each door. Each switch is concealed within and integral to its respective door latch unit. The switches are momentary leaf contact-type units that are actuated by the mechanisms internal to the door latch. A short pigtail wire and connector on each door latch connects the door ajar switch to the vehicle electrical system through its respective door wire harness.

The door ajar switches cannot be adjusted or repaired and, if ineffective or damaged, the door latch unit must be replaced. (Refer to 23 - Body/Door - Front/LATCH, Door - Removal) or (Refer to 23 - Body/Doors - Rear/LATCH, Door - Removal) .

SWING GATE

SWING GATE

A swing gate ajar switch is standard equipment on this vehicle. The switch is concealed within and integral to the swing gate latch unit. The switch is a momentary leaf contact-type unit that is actuated by the swing gate latch mechanism. An integral connector receptacle on the swing gate latch connects the swing gate ajar switch to the vehicle electrical system through the swing gate wire harness.

The swing gate ajar switch cannot be adjusted or repaired and, if ineffective or damaged, the swing gate latch unit must be replaced. (Refer to 23 - Body/Decklid/Hatch/Liftgate/Tailgate/LATCH - Removal) .

DOOR

The door ajar switches are actuated by the mechanisms internal to the door latch. When a door is closed and properly latched, its door ajar switch is an open circuit. When a door is open or only partially latched, the door ajar switch is a closed circuit. The door ajar switches are hard wired in series between a body ground and the Totally Integrated Power Module (TIPM). The TIPM reads the hard wired door ajar switch inputs through internal pull-ups, then uses these inputs to control many electronic functions and features of the vehicle. The TIPM also sends electronic door ajar switch status messages over the Controller Area Network (CAN) data bus.

The door ajar switches as well as the hard wired inputs and outputs of the switches may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information.
