DOOR AJAR SWITCH
DESCRIPTION
This vehicle has four door ajar switches, one for
each door. Each switch is concealed within and inte-
gral to its respective door latch unit. The switches
are momentary leaf contact-type units that are actu-
ated by the door latch mechanisms. 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
faulty or damaged, the door latch unit must be
replaced. (Refer to 23 - BODY/DOOR - FRONT/
LATCH - REMOVAL) or (Refer to 23 - BODY/DOOR -
REAR/LATCH - REMOVAL).
OPERATION
The door ajar switches are actuated by the door
latch mechanisms. When a door is closed and prop-
erly 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 between a body ground and
the Body Control Module (BCM). The driver side
front door ajar switch is connected to the BCM
through a driver door ajar switch sense circuit, while
the remaining three door ajar switches are connected
to the BCM through a passenger door ajar switch
sense circuit in a parallel-series arrangement. The
BCM reads the door ajar switch status through an
internal pull-up, then uses these inputs to control
many electronic functions and features of the vehicle.
The door ajar switches can be diagnosed using con-
ventional diagnostic tools and methods; however, for
proper diagnosis of the BCM, and both the hard
wired and electronic BCM outputs affected by the
door ajar switch inputs, a DRBIIItscan tool is
required. Refer to the appropriate diagnostic infor-
mation.
FLIP-UP GLASS AJAR SWITCH
DESCRIPTION
A flip-up glass ajar switch is standard equipment
in this vehicle. This switch is concealed within and
integral to the flip-up glass latch unit. The switch is
a momentary leaf contact-type unit that is actuated
by the flip-up glass latch mechanism. A dedicated
connector receptacle on the flip-up glass latch unit
connects the flip-up glass ajar switch to the vehicle
electrical system through the tailgate wire harness.
The flip-up glass ajar switch cannot be adjusted or
repaired and, if faulty or damaged, the flip-up glass
latch unit must be replaced. (Refer to 23 - BODY/
SWING GATE/FLIP-UP GLASS LATCH - REMOV-
AL).
OPERATION
The flip-up glass ajar switch is actuated by the
flip-up glass latch mechanism. When the flip-up glass
is closed and properly latched, the flip-up glass ajar
switch is an open circuit. When the flip-up glass is
open or only partially latched, the flip-up glass ajar
switch is a closed circuit. The flip-up glass ajar
switch is hard wired between a body ground, the
Body Control Module (BCM), and the rear wiper
motor. The output of the switch is connected to the
BCM and rear wiper motor through a flip-up glass
ajar switch sense circuit. The BCM reads the flip-up
glass ajar switch status through an internal pull-up,
then uses this input to control many electronic func-
KJLAMPS/LIGHTING - INTERIOR 8L - 77
COURTESY LAMP UNIT (Continued)

tions and features of the vehicle. The rear wiper
motor uses this input to restrict rear wiper operation
when the flip-up glass is ajar. The flip-up glass ajar
switch can be diagnosed using conventional diagnos-
tic tools and methods; however, for proper diagnosis
of the BCM, and both the hard wired and electronic
BCM outputs affected by the flip-up glass ajar switch
input, a DRBIIItscan tool is required. Refer to the
appropriate diagnostic information.

TAILGATE AJAR SWITCH
DESCRIPTION
A tailgate ajar switch is standard equipment in
this vehicle. This switch is concealed within and inte-
gral to the tailgate latch unit. The switch is a
momentary leaf contact-type unit that is actuated by
the tailgate latch mechanism. A pigtail wire harness
and connector on the tailgate latch unit connects the
tailgate ajar switch to the vehicle electrical system
through the tailgate wire harness. The tailgate ajar
switch cannot be adjusted or repaired and, if faulty
or damaged, the tailgate latch unit must be replaced.
(Refer to 23 - BODY/SWING GATE/LATCH -
REMOVAL).
OPERATION
The tailgate switch is actuated by the tailgate
latch mechanism. When the tailgate is closed and
properly latched, the tailgate ajar switch is an open
circuit. When the tailgate is open or only partially
latched, the tailgate ajar switch is a closed circuit.
The tailgate ajar switch is hard wired between a
body ground and the Body Control Module (BCM).
The output of the switch is connected to the BCM
through a tailgate ajar switch sense circuit. The
BCM reads the tailgate ajar switch status through
an internal pull-up, then uses this input to control
