Window Ajar Switch: Description and Operation
Flip-Up Glass Ajar Switch - Operation
FLIP-UP GLASS
The liftgate flip-up glass ajar switch is actuated by the flip-up glass latch mechanism. When the flip-up glass is closed and properly latched, its ajar
switch is an open circuit. When the glass is open or only partially latched, the ajar switch is a closed circuit. The flip-up glass ajar switch is hard wired in
series between a body ground and the Totally Integrated Power Module (TIPM). The TIPM reads the hard wired flip-up glass 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 flip-up glass
ajar switch status messages over the Controller Area Network (CAN) data bus.
The flip-up glass 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.
