Trunk / Liftgate Ajar Switch: Description and Operation
Operation
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 ElectroMechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN). The EMIC 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 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.
