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.

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