battery replacement JEEP CHEROKEE 1994 Service Service Manual

A voltage drop of one-half the full amount, approx-
imately 6 volts, indicates a good grid or closed cir-
cuit.
A voltage drop of 12 volts at the centerline indi-
cates a break in the grid between the positive volt-
meter lead and the ground.
No voltage drop (0 volts) at the centerline indicates
a break in the grid between the centerline and the
voltage source or lead.
The exact location of the break can be pinpointed
by moving positive voltmeter lead to the left or right
along grid. An abrupt change in the voltage reading
will be noticed. The break is at that point in the
grid.
REAR WINDOW DEFOGGER GRID REPAIR
Locate the broken or open grid.
Use the grid repair kit (available as a service part)
by using the following procedure:
(1) Mark the location of the broken or open grid on
the exterior surface of the glass using a suitable
marking pencil.
(2) Lightly rub the area to be repaired (inside the
rear window) using fine steel wool. Clean the area
with alcohol.
(3) Attach two strips of masking tape to the inside
surface of the rear window (above and below the
break in the grid) (Fig. 1).
(4) Remove package separator clamp and mix plas-
tic conductive epoxy thoroughly. Fold in half and cut
center corner to dispense epoxy.
(5) Apply conductive epoxy through slit in mask-
ing tape. Overlap both ends of the break.
(6) For a terminal or pigtail replacement, mask ad-
jacent areas so epoxy can be extended onto line and
buss bar. Apply a thin layer of epoxy to area where
terminal was fastened and to adjacent line.
(7) Apply a thin layer of conductive epoxy on ter-
minal and place terminal on desired location. To pre-
vent terminal from moving while the epoxy is curing,
it must be wedged or clamped.
(8) Carefully remove masking tape from grid line.
(9) Allow epoxy to cure 24 hours at room tempera-ture or use heat gun with a 260É-371ÉC (500É-700ÉF)
range for 15 minutes. Hold gun approximately
254mm (10 inches) from repaired area.
(10) After conductive epoxy is properly cured re-
move wedge from terminal and check out operation
of rear window defogger. Do not attach connectors
until curing is complete.

GENERAL
The door lock actuators, including liftgate, are con-
trolled by two-way switches. To lock the doors, push
down on either switch. To unlock doors from inside
the vehicle push upward on either switch.
The power door locks do not lock or unlock the
doors from outside the vehicle. Insert the key into
the lock cylinder to lock or unlock each individual
door.
DESCRIPTION
The door locks are operated by reversible motors
that receive voltage from fuse #13 in the fuse panel.
Voltage is applied to the driver's side door lock
switch and the passenger's side door lock switch
through the #9 fuse. With the driver's side door lock
switch in LOCK, voltage is applied through the
switch to the door lock relay coil. The relay coil is
energized which closes the circuit from the circuit
breaker to the lock motor. The motor is grounded by
the unlock relay.
The passenger's side door lock window switch oper-
ates the same as the driver's door switch. The volt-
age and ground paths are reversed to unlock the
doors.
The power door lock operates with battery power
and, therefore, is independent of the ignition switch.
DIAGNOSING POWER DOOR LOCKS
If vehicle has Keyless Entry and the door locks op-
erate properly using door switches but do not work
with transmitter, refer to Keyless Entry in this
group.

SYSTEM DESCRIPTION
The keyless entry system consists of a portable re-
mote control transmitter and a receiver mounted in
the overhead console or between the sun visors. Sys-
tem operation is based on a coded infrared signal
from the transmitter to the receiver. The transmitter
is programmed into the receiver providing the correct
programming sequence is met.
When the keyless entry system is activated, the cor-
responding relay operates to supply voltage to the mo-
tors. The use of either relay determines the polarity of
the voltage that is supplied to the door lock motors.
When the keyless entry system is used, the trans-
mitter sends a signal to the keyless entry module. If
the doors are unlocked, the module activates a tran-
sistor switch to apply voltage to the lock relay coil.
The coil is energized to close the normally open con-
tacts of the lock relay. Battery voltage from the relay
is applied to the door lock motors to lock the doors.
Current flows in the same path to ground as it does
when the master door lock switch is used.When the doors are locked, the keyless entry mod-
ule applies voltage to the unlock relay coil and a
similar action takes places to unlock the doors.
TRANSMITTER
The pocket size, solid state transmitter operates on
(2) 3-volt lithium (CR1616) batteries (Fig. 1). The
transmitter is activated by pressing either the LOCK
or UNLOCK button. This closes the internal contacts
that complete the battery circuit.
The battery voltage activates the transmitter diode
which in turn generates a coded infrared signal. The
signal is transmitted as pulses of infrared light.
If the red LED on the side of the transmitter does
not light when the transmitter is activated, the bat-
teries are low.
RECEIVER
The receiver is in circuit with the electric door lock
system. The coded infrared signal is picked up by the
receiver diode and is shaped, amplified and decoded by
an integrated circuit within the receiver. If the signal
Fig. 10 Latch Assembly Removal/Installation
8P - 8 POWER DOOR LOCKSJ

code received matches the code in the receiver memory
circuit, the receiver triggers the door lock/unlock relays.
The relays complete the circuit to the electric door lock
solenoid to either lock or unlock the doors.
SYSTEM OPERATION
To activate the system, aim the transmitter diode
toward the receiver and press the transmitter signal
button to lock or unlock the doors as desired.
Effective transmitter range is 4.75 meters (15 ft.)
with the transmitter positioned no more than 45 de-
grees from the receiver centerline.
For complete circuit diagrams refer to Group
8W - Wiring Diagrams.
TRANSMITTER PROGRAMMING
Up to 4 Transmitter Identification Codes (TIC's) can
be programed into the receiver at any given time.
(1) Open the driver's door of the vehicle. Leave it
open through the programming procedure.
(2) Move the mechanical door lock lever to the
LOCK position.
(3) Turn the ignition switch to the ON position.
(4) Within 20 seconds, aim a transmitter at the re-
ceiver dome and press the LOCK button for at least
5 seconds. Once the receiver accepts the program-
ming code, the driver's door will unlock.
(5) Once the first transmitter has been pro-
grammed, additional transmitters (up to 4) may be
programmed into the receiver. Within 20 seconds of
the previous transmitter programming, move the me-
chanical door lock lever to the LOCK position. Aimanother transmitter at the receiver dome and press
the LOCK button for at least 5 seconds. The door
lock will cycle again.
(6) To lock the programmed codes into the re-
ceiver, the ignition switch must be turned OFF and
back ON within 20 seconds after programming the
last transmitter's code. At that time, all previous
codes are erased from the module.

TRANSMITTER SERVICE
If the receiver malfunctions, only the receiver will
have to be replaced. The new receiver will have to be
reprogrammed. If a transmitter is lost, replace the
transmitter and reprogram the receiver.

GENERAL.............................. 1POWER SEAT MOTOR REPLACEMENT....... 2
SWITCH TESTING....................... 2
GENERAL
The power seat can be adjusted in 6 different direc-
tions (Fig. 1). The control switch is on the lower out-
board side of the seat.
The front lever on the switch raises or lowers (tilts)
the front of the seat cushion. The center lever raises
or lowers the complete seat by moving the switch up
or down. The center lever also moves the seat for-
ward or rearward by moving the switch forward or
rearward. The rear lever raises or lowers (tilts) the
back of the seat cushion.
There are 3 reversible motors that operate the
power seat. The front and rear of the seat are oper-
ated by different motors. They can be raised or low-
ered independently of each other. Moving the center
position seat switch to either the UP or DOWN posi-
tion, runs both the front and rear motors at the same
time.
The forward-rearward motor is operated by the
center position seat switch. When the switch is held
in the FORWARD position, battery voltage is applied
through the switch contacts to pin S3 and the for-ward-rearward motor. The motor is grounded
through pin S4 and the contacts of the back switch to
pin 2 and to ground. The motor runs to drive the seat
forward until the switch is released.
With the switch in the REAR position, pin S4 re-
ceives battery voltage and pin S3 is grounded. This
reversed polarity causes the motor to run in the op-
posite direction and drive the seat backward.
The front motor works in a similar way when the
front height switch is operated.
To raise the entire seat, the center position seat
switch is held in the UP position. This applies bat-
tery voltage to both pins S1 and S5 and the front and
rear motors. Pins S2 and S6 are grounded through
the down switches and the lower switch. Both motors
run to drive the entire seat up. A similar action oc-
curs to move the entire seat down.
Each motor contains a self-resetting circuit breaker
to protect it from overload. Consecutive or frequent
resetting must not be allowed to continue. Make nec-
essary repairs.
DIAGNOSIS
Refer to Group 8W-Wiring Diagrams for a complete
circuit diagram.
Before any testing is attempted the battery should
be fully charged and all connections and pins cleaned
and tightened to insure proper continuity and
grounds.
With the dome light on, apply switch in direction
of the failure. If the dome light dims, the seat may
be jamming. Check for binding. If the dome light
does not dim, then proceed with the following electri-
cal tests.
SEAT MOTOR ASSEMBLY
²Position seat switch to move all 3 seat motors. The
seat should move in all directions. If not, go to No

WINDOW REGULATOR REPLACEMENT...... 9
DESCRIPTION
All XJ vehicles, equipped with power windows,
have a cable driven window regulator system. A per-
manent magnet motor moves each power window.
Each motor raises or lowers the glass when voltage
is supplied to the motor. The direction the motor
turns depends on the polarity of the supply voltage.
The control switches control the supply voltage polar-
ity.
With the ignition switch in the ON position voltage
from the 60 amp fuse in the Power Distribution Cen-
ter is applied through the power window circuit
breaker. Power then goes to the master switch termi-
nal BY and to the passenger's window switches.
When the driver's window switch is moved UP, the
contacts close a current path to:
²terminal DV
²driver's side front window motor
²terminal CV
²the DOWN contact of the driver's side front win-
dow to ground.
The motor then moves the glass up.
Current flows in a similar way when the UP con-
tact in one of the passenger's window switches is
closed. Current flow through the passenger's window
motors must go through the driver's and the passen-
ger's window switches before it reaches ground.
Each motor is protected by a built-in circuit
breaker. If a window switch is held on too long with
the window obstructed or after the window is fully
up or down, the circuit breaker opens the circuit. The
circuit breaker resets automatically as it cools. Do
not allow frequent or consecutive resetting of the cir-
cuit breaker to continue.

GENERAL
For information concerning wiring or connectors,

The mirror control switch contains two separate
switches, the operating switch and the selector
switch.
Each mirror has two reversible motors: one to ad-
just the mirror view up and down, the other to adjust
the mirror view right and left. The driver operates
three switches that control the polarity of the voltage
to the motors. The mirror select switch directs these
control voltages to either the right or left mirror.
The mirror select switch must be set to L or R to
direct current flow. If the mirror select switch is set
on R and the up-down switch is moved to the UP po-
sition, the voltage path is:
²through the U contact of switch 1
²to pin E
²to the up-down motor in the right mirror.
The ground path is:
²through pin D
²through the mirror select switch contacts
²to the U contacts of switch 3 and switch 2
²to pin F
²to ground.
The right motor runs and tilts the mirror up.
If the switch is pushed to the DOWN position, thesame motor receives voltage. Now the polarity is re-
versed, with pin E grounded. The motor runs in the
opposite direction.
The right mirror left-right motor operates in a sim-
ilar manner when the control switch is moved to the
L or R positions.
The left mirror works the same way as the right
mirror when mirror select switch is moved to L posi-
tion and control switch is operated.

GENERAL.............................. 1
IGNITION KEY WARNING SWITCH REPLACEMENT.4OPERATION/DIAGNOSIS.................. 1
GENERAL
The buzzer or optional chime module is mounted on
the left side of the fuse block (above and to the left of
the brake/clutch pedal). The buzzer or chime sounds
an audible warning tone in any of the following con-
ditions:
²Vehicle lights are ON when the ignition has been
switched OFF and the key is removed and then the
driver's door is opened (except YJ).²The key is in the ignition and the driver's door is
open (On some vehicles, the buzzer will not sound if
the ignition switch is in the ON position).
²The ignition is switched ON and the driver's seat
belt is not buckled. Buzzer will quit after 4 to 8 sec-
onds. Besides the buzzer, a seat belt indicator lamp
turns on as a reminder to fasten seat belt.
OPERATION/DIAGNOSIS
OPERATION
Battery voltage for module operation is supplied to
two pins. Voltage is always present at pin 7. Pin 1
receives voltage when the ignition switch is in the
ON or START position.
SEAT BELT WARNING
The seat belt warning system uses both visual and
audible signals. These consist of a buzzer that is part
of a combined seat belt and key warning buzzer and
a red light on the instrument panel.
The system will always illuminate the seat belt
warning lamp for four to eight seconds when the ig-
nition switch is turned to the ON position. Also, only
if the driver does not fasten his seat belt, the buzzer
will sound during the same time interval. Passenger
belts are not connected to the system.
A timed buzzer-relay is used to operate the system
for the time period. It has a time delay mechanism
and buzzer assembly. Only the driver's seat belt
buckle has a switch that is connected to the system.
KEY-IN-IGNITION WARNING
To sound the key-in-ignition warning, the following
must occur:
²the ignition key warning switch must be closed
²the driver's door jamb switch must be closed.
These conditions ground pin 6 of the module. These
switches are closed when the key is in the ignition
and the driver's door is open.On some vehicles the chime/buzzer will not
sound if the door is open and the key is in the
ON position.
LIGHTS-ON WARNING (EXCEPT YJ)
To sound the lights-on warning, the following must
occur:
²the headlamp switch must be closed
²the driver's door jamb switch must be closed.
These conditions ground pin 6 of the module. These
switches are closed when the headlamp switch is ON
and the driver's door is open.
DIAGNOSIS
If the buzzer/chime unit does not operate as de-
scribed, check the two fuses for pins 1 and 7 (Figs. 1
and 2) and replace as required. If the fuses are not
defective, perform the following tests to determine if
the problem is in the module or in the wiring. Using
a flat head screwdriver, release the locking plastic
clip while carefully pulling out the module. Plug in a
known good module and check its operation. If the
problem is not corrected by replacing the module, re-
move the module and continue as follows:
VOLTAGE TESTS
Ignition in ON position, measure between the
following pins and vehicle ground.
²Measure voltage at buzzer/chime module connector
pin 1. Meter should read battery voltage. If not, re-
pair open to ignition switch.
Turn ignition OFF and remove the key from the ig-
nition.
