2002 JEEP GRAND CHEROKEE lift gate trim

The RKE system includes two transmitters when
the vehicle is shipped from the factory, but the sys-
tem can retain the vehicle access codes of up to four
transmitters. The transmitter codes are retained in
the RKE receiver memory, even if the battery is dis-
connected. If an RKE transmitter is faulty or lost,
new transmitter vehicle access codes can be pro-
grammed into the system using a DRBIIItscan tool
and the appropriate diagnostic information.
This vehicle also offers several customer program-
mable features, which allows the selection of several
optional electronic features to suit individual prefer-
ences. (Refer to 8 - ELECTRICAL/OVERHEAD CON-
SOLE/ELECTRONIC VEHICLE INFO CENTER -
DESCRIPTION). Customer programmable feature
options affecting the RKE system include:
²Remote Unlock- Allows the option of having
only the driver side front door unlock when the RKE
transmitter Unlock button is depressed the first time
and the remaining doors and the liftgate unlock
when the button is depressed a second time, or hav-
ing all doors and the liftgate unlock upon the first
depression of the RKE transmitter Unlock button.
²Remote Linked to Memory- If the vehicle is
equipped with the Memory System, this feature
allows the option of having the RKE transmitter
Unlock button activate the recall of the stored set-
tings, or having the recall function assigned solely to
the memory switch on the driver side front door trim
panel.
²Sound Horn on Lock- Allows the option of
having the horn sound a short chirp as an audible
verification that the doors have locked, or having no
audible verification.
²Flash Lights with Lock- Allows the option of
having the lights flash as an optical verification that
the doors have locked, or having no optical verifica-
tion.
This group covers the following components of the
RKE system:
²RKE Receiver
²RKE Transmitter
Certain functions and features of the RKE system
rely upon resources shared with other electronic
modules in the vehicle over the Programmable Com-
munications Interface (PCI) data bus network. The
PCI data bus network allows the sharing of sensor
information. This helps to reduce wire harness com-
plexity, internal controller hardware, and component
sensor current loads. At the same time, this system
provides increased reliability, enhanced diagnostics,
and allows the addition of many new feature capabil-
ities. For diagnosis of these electronic modules or of
the PCI data bus network, the use of a DRBIIItscan
tool and the appropriate diagnostic information are
required.The other electronic modules that may affect RKE
system operation are as follows:
²Body Control Module (BCM)- (Refer to 8 -
ELECTRICAL/ELECTRONIC CONTROL MOD-
ULES/BODY CONTROL/CENTRAL TIMER MOD-
ULE - DESCRIPTION).
²Driver Door Module (DDM)- (Refer to 8 -
ELECTRICAL/ELECTRONIC CONTROL MOD-
ULES/DOOR MODULE - DESCRIPTION).

Hard wired circuitry connects the RKE system
components via the PDM to the electrical system of
the vehicle. These hard wired circuits are integral to
several wire harnesses, which are routed throughout
the vehicle and retained by many different methods.
These circuits may be connected to each other, to the
vehicle electrical system and to the RKE system com-
ponents through the use of a combination of soldered
splices, splice block connectors, and many different
types of wire harness terminal connectors and insu-
lators. Refer to the appropriate wiring information.
The wiring information includes wiring diagrams,
proper wire and connector repair procedures, further
details on wire harness routing and retention, as well
as pin-out and location views for the various wire
harness connectors, splices and grounds.
COMBINATION FLASHER
The combination flasher is a smart relay that func-
tions as both the turn signal system and the hazard
warning system flasher. The combination flasher con-
tains active electronic Integrated Circuitry (IC) ele-
ments. This flasher can be energized by the BCM to
flash all of the park/turn signal/front side marker
lamps as an optical alert for the RKE panic function
and, if the Flash Lights with Lock programmable fea-
ture is enabled, as an optical verification for the RKE
lock event. (Refer to 8 - ELECTRICAL/LAMPS/
LIGHTING - EXTERIOR/COMBINATION FLASHER

DIAGNOSIS AND TESTING - POWER LOCK
MOTOR
Remember, the Driver Door Module (DDM) cir-
cuitry controls the output to the driver side front
door power lock motor. The Passenger Door Module
(PDM) circuitry controls the output to the power lock
motors for the remaining doors and the liftgate.
Refer to the appropriate wiring information. The wir-
ing information includes wiring diagrams, proper
wire and connector repair procedures, details of wire
harness routing and retention, connector pin-out
information and location views for the various wire
harness connectors, splices and grounds.
(1) Check each power lock motor for correct opera-
tion while moving the power lock switch to both the
Lock and Unlock positions. If all of the power lock
motors are inoperative, go to Step 2. If one power
lock motor is inoperative, go to Step 3.
(2) If all of the power lock motors except the driver
side front door are inoperative, the problem may be
caused by one shorted motor. Disconnecting a shorted
power lock motor from the power lock circuit will
allow the good power lock motors to operate. Discon-
nect the wire harness connector from each PDM-con-
trolled power lock motor, one at a time, and recheck
both the lock and unlock functions by operating the
power lock switch. If all of the PDM-controlled power
lock motors are still inoperative after the above test,
check for a short or open circuit between the power
lock motors and the PDM. If disconnecting one power
lock motor causes the other motors to become func-
tional, go to Step 3 to test the power lock motor that
was last disconnected.
(3) Once it is determined which power lock motor
is inoperative, that motor can be tested as follows.
Disconnect the door or liftgate wire harness connec-
tor from the inoperative power lock motor. Apply 12
volts to the lock and unlock driver circuit cavities of
the power lock motor connector to check its operation
in one direction. Reverse the polarity to check the
motor operation in the opposite direction. If OK,
repair the shorted or open circuits between the lock
motor and the DDM or PDM as required. If not OK,
replace the faulty power lock motor.
POWER LOCK SWITCH
DESCRIPTION
The power lock motors are controlled by a two-way
momentary switch mounted on the trim panel of each
front door. Each power lock switch is illuminated by
a Light-Emitting Diode (LED) that is integral to the
switch paddle.
The driver side front door power lock switch is
integral to the Driver Door Module (DDM), and the
passenger side front door power lock switch is inte-
gral to the Passenger Door Module (PDM). The
power lock switches and their lamps cannot be
adjusted or repaired and, if faulty or damaged, the
entire DDM or PDM unit must be replaced. (Refer to
8 - ELECTRICAL/ELECTRONIC CONTROL MOD-
ULES/DOOR MODULE - DESCRIPTION).
OPERATION
The front door power lock switches provide a lock
and unlock signal to the door module circuitry. The
Driver Door Module (DDM) circuitry controls the out-
put to the driver side front door power lock motor,
while the Passenger Door Module (PDM) circuitry
controls the output to the passenger side front door,
both rear door and the liftgate power lock motors.
When the DDM-integrated power lock switch is
actuated, the DDM circuitry sends control outputs to
the driver side front door power lock motor and sends
a message to the PDM over the Programmable Com-
munications Interface (PCI) data bus to control the
output to the passenger side front door, both rear
door and the liftgate power lock motors. When the
PDM-integrated power lock switch is actuated, the
PDM circuitry sends control outputs to the passenger
side front door, both rear door and the liftgate power
lock motors and sends a message to the DDM over
the Programmable Communications Interface (PCI)
data bus to control the output to the driver side front
door power lock motor.
Each power lock switch is illuminated by a Light-
Emitting Diode (LED) when the ignition switch is
turned to the On position. See the owner's manual in
the vehicle glove box for more information on the fea-
tures, use and operation of the power lock switches.

along the left roof side rail to the rear of the vehicle.
At the rear of the vehicle, the headliner hose is
routed above the headliner and along the upper lift-
gate opening panel toward the right side of the vehi-
cle. The headliner hose then passes through a hole
with a rubber grommet in the upper liftgate opening
panel and through another hole with a rubber grom-
met into the upper inner liftgate panel to the rear
washer nozzle.
Washer hose is available for service only as roll
stock, which must then be cut to length. The head-
liner washer hose is integral to the headliner unit
and, if faulty or damaged, the headliner unit must be
replaced. The molded plastic washer hose fittings
cannot be repaired. If these fittings are faulty or
damaged, they must be replaced.
OPERATION
Washer fluid in the washer reservoir is pressurized
and fed by the rear washer pump/motor through the
rear washer system plumbing and fittings to the rear
washer nozzle on the liftgate outer panel above the
liftgate glass. Whenever routing the washer hose or a
wire harness containing a washer hose, it must be
routed away from hot, sharp, or moving parts; and,
sharp bends that might pinch the hose must be
avoided.
REAR WASHER NOZZLE
DESCRIPTION
The rear washer nozzle is a fluidic type unit that
includes an integral check valve (Fig. 3). The nozzle
is constructed of molded plastic and has a rubber
seal and integral snap features on the back of it. The
nozzle is secured by a snap fit in a dedicated mount-
ing hole in the liftgate outer panel above the liftgate
flip-up glass. Within the rear nozzle body, a small
check ball is held against an integral valve seat at
the inlet end of the nozzle by a small coiled spring.
The rear washer nozzle and check valve unit cannot
be adjusted or repaired. If faulty or damaged, the
entire nozzle and check valve unit must be replaced.
OPERATION
The rear washer nozzle is designed to dispense
washer fluid into the wiper pattern area on the out-
side of the liftgate glass. Pressurized washer fluid is
fed to the nozzle from the washer reservoir by the
rear washer pump/motor through a single hose,
which is attached to a barbed nipple on the back of
the rear washer nozzle. The rear washer nozzle
incorporates a fluidic design, which causes the nozzle
to emit the pressurized washer fluid as an oscillating
stream to more effectively cover a larger area of the
glass area to be cleaned. The integral rear nozzle
check valve prevents washer fluid from draining out
of the rear washer supply hoses back to the washer
reservoir. This drain-back would result in a lengthy
delay from when the rear washer switch is actuated
until washer fluid was dispensed through the rear
washer nozzle, because the rear washer pump would
have to refill the rear washer plumbing from the res-
ervoir to the nozzle. The check valve also prevents
washer fluid from siphoning through the rear washer
nozzle after the rear washer system is turned Off.
When the rear washer pump pressurizes and pumps
washer fluid from the reservoir through the rear
washer plumbing, the fluid pressure overrides the
spring pressure applied to the check ball within the
valve and unseats the check ball, allowing washer
fluid to flow to the rear washer nozzle. When the
rear washer pump stops operating, spring pressure
seats the check ball in the valve and fluid flow in
either direction within the rear washer plumbing is
prevented.
REMOVAL
The check valve for the rear washer nozzle is inte-
gral to the nozzle.
(1) Using a trim stick or another suitable wide
flat-bladed tool, gently pry at the sides of the rear
washer nozzle to release the snap features that
secure it in the mounting hole of the liftgate outer
panel.

motor that is secured with screws to the wiper motor
and to the liftgate inner panel.
²Electronic Controls- The rear wiper module
electronic controls include the rear wiper system
electronic logic and rear wiper motor electronic con-
trols. The electronic controls for the motor include an
electronic speed control that speeds the wiper blade
near the center of the glass, but slows the wiper
blade during directional reversals at each end of the
wipe pattern and during wiper blade off-the-glass
parking for quieter operation.
²Motor- The permanent magnet rear wiper
motor is secured with screws to the rear wiper mod-
ule bracket. The wiper motor includes an integral
transmission, and the motor output shaft.
The rear wiper module cannot be adjusted or
repaired. If any component of the module is faulty or
damaged, the entire rear wiper module unit must be
replaced. The motor output shaft gasket, bezel, nut,
and nut cover are available for service replacement.
OPERATION
The rear wiper module receives non-switched bat-
tery current through a fuse in the Junction Block
(JB) and is grounded at all times. The rear wiper
module operation is controlled by the vehicle operator
through battery current signal inputs received by the
rear wiper module electronic controls from the right
multi-function switch on the steering column. The
module also receives an external control input from
the liftgate flip-up glass ajar switch circuit. The rear
wiper module electronic control logic uses these
inputs, its internal inputs, and its programming to
provide continuous wipe, delay wipe, wipe-after-wash
and off-the-glass wiper blade parking. The wiper
blade cycling is controlled by the rear wiper module
electronic controls, which control current flow to the
wiper motor brushes. The wiper motor transmission
converts the rotary output of the wiper motor to the
back and forth wiping motion of the rear wiper arm
and blade on the liftgate glass.
