Door Switch: Description and Operation
Operation
Door
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.
Liftgate
LIFTGATE
The liftgate ajar switch is actuated by the liftgate latch mechanism. When the liftgate is closed and properly latched, its liftgate ajar switch is an open
circuit. When the liftgate is open or only partially latched, the liftgate ajar switch is a closed circuit. The liftgate ajar switch is hard wired in series
between a body ground and the Totally Integrated Power Module (TIPM). The TIPM reads the hard wired liftgate ajar switch input through an internal
pull-up, then uses this input to control many electronic functions and features of the vehicle. The TIPM also sends electronic liftgate ajar switch status
messages over the Controller Area Network (CAN) data bus.
