To test ignition coil-to-distributor cap cable, do not
remove the cable from the cap. Connect ohmmeter to
rotor button (center contact) of distributor cap and
terminal at ignition coil end of cable. If resistance is
not within specifications as found in the Spark Plug
Cable Resistance chart, remove the cable from the
distributor cap. Connect the ohmmeter to the termi-
nal ends of the cable. If resistance is not within spec-
ifications as found in the Spark Plug Cable
Resistance chart, replace the cable. Inspect the igni-
tion coil tower for cracks, burns or corrosion.
For removal and installation of spark plug cables,
refer to Spark Plug Secondary Cables in the Compo-
nent Removal/Installation section.

ON-BOARD DIAGNOSTICS
FOR CERTAIN IGNITION SYSTEM
COMPONENTS
The powertrain control module (PCM) performs an
On-Board Diagnostic (OBD) check for certain ignition
system components on all vehicles. This is done by
setting a diagnostic trouble code (DTC).
A DTC can be obtained in two different ways. One
of the ways is by connecting the DRB scan tool to the
data link connector. This connector is located in the
engine compartment (Figs. 26 or 27). Refer to the ap-
propriate Powertrain Diagnostic Procedures service
manual for operation of the DRB scan tool. The other
way is to cycle the ignition key and observe the mal-
function indicator lamp (MIL). The MIL lamp is dis-
played on the instrument panel as the CHECK
ENGINE lamp (Figs. 28 or 29). This lamp will flash
a numeric code. If a numeric code number 11 (for the
crankshaft position sensor) or 42 (for the ASD relay)
is observed, a problem has been found in the ignition
system.
Note that the CHECK ENGINE lamp will illumi-
nate initially for approximately two seconds each
time the ignition key is turned to the ON position.
This is done for a bulb test.

clamp (Fig. 8).
(8) Remove the distributor from engine by slowly
lifting straight up.
Note that the rotor will rotate slightly in a counter-
clockwise direction while lifting up the distributor.
The oil pump gear will also rotate slightly in a coun-terclockwise direction while lifting up the distributor.
This is due to the helical cut gears on the distributor
and camshaft.
Note the removed position of the rotor during dis-
tributor removal. During installation, this will be re-
ferred to as the Pre-position.

8D - 20 IGNITION SYSTEMSJ

ANTENNA
All models use a fixed-length stainless steel rod-
type antenna mast, installed at the right front (fend-
er on XJ, cowl side on YJ) of the vehicle. The
antenna mast is connected to the center wire of the
coaxial antenna cable and is not grounded to any
part of the vehicle.
To eliminate static, the antenna base must have a
good ground. The coaxial antenna cable shield (the
outer wire mesh of the cable) is grounded to the an-
tenna base and the radio chassis.
The factory installed ETRs automatically compen-
sate for radio antenna trim. Therefore, no antenna
trimmer adjustment is required or possible when re-
placing the receiver or the antenna.
RADIO NOISE SUPPRESSION
Radio Frequency Interference (RFI) and Electro-
Magnetic Interference (EMI) noise suppression is ac-
complished primarily through circuitry internal to
the radio receivers. These internal suppression de-
vices are only serviced as a part of the radio receiver.External suppression devices that are serviceable
and should be checked in the case of RFI or EMI
noise complaints include the following:
²radio antenna base ground
²engine-to-body ground strap
²resistor-type spark plugs
²radio suppression-type secondary ignition wiring.
In addition, if the source of RFI or EMI noise is
identified as a component on the vehicle (i.e.:genera-
tor, blower motor, etc.), the ground path for that com-
ponent should be checked. If excessive resistance is
found in that circuit, repair as required before con-
sidering any component replacement.
Fleet vehicles are available with an extra-cost RFI-
suppressed Powertrain Control Module (PCM). This
unit reduces interference generated by the PCM on
some radio frequencies used in two-way radio com-
munications. However, this unit will not resolve com-
plaints of RFI in the commercial AM or FM radio
frequency ranges.
DIAGNOSIS
RADIO
CAUTION: Do not operate the radio with speaker
leads detached since damage to the transistors
may result.
(1) Check fuse 2 in fuseblock module and fuse in
back of radio chassis. If OK, go to next step. If not
OK, replace fuse.
(2) Turn ignition switch to ON position. Check for
battery voltage at fuse 2. If OK, go to next step. If
not OK, repair circuit to ignition switch as required.
(3) Turn ignition switch to OFF position. Discon-
nect battery negative cable. Remove instrument clus-
ter bezel. Remove radio, but do not unplug any
connections. Check for continuity between the radio
chassis and a good ground. There should be continu-
ity. If OK, go to next step. If not OK, repair radio
ground circuit as required.
(4) Connect battery negative cable. Turn ignition
switch to ON position. See Radio Connections chart.
Check for battery voltage at cavity 3 of radio connec-
tor. If OK, go to next step. If not OK, repair circuit to
fuse 2 as required.
(5) Turn ignition switch to OFF position. Check for
battery voltage at cavity 4 of radio connector. If OK,
replace radio. If not OK, repair circuit to IOD fuse in
PDC as required.
SPEAKERS
CAUTION: Do not operate the radio with speaker
leads detached since damage to the transistors
may result.
(1) Turn radio on and adjust balance and fader
controls to check performance of each individual
speaker. Note the speaker locations that are not per-
forming correctly. Go to next step.
(2) Turn radio off. Disconnect battery negative ca-
ble. Remove instrument cluster bezel and remove ra-
dio. See Radio Connections chart. Check both the
speaker feed and return cavities at radio for continu-
ity to a good ground. There should be no continuity.
If OK, go to next step. If not OK, repair wiring cir-
cuit as required.
(3) Check resistance between speaker feed and re-
turn cavities. Meter should read between 3 and 8
ohms (speaker impedance). If OK, see diagnosis for
Radio. If not OK, go to next step.
(4) Unplug speaker wiring connector. Check for
continuity between speaker feed cavity at radio and
at speaker. Repeat check between speaker return
cavity at radio and at speaker. If OK, replace
speaker. If not OK, repair wiring circuit as required.
8F - 2 AUDIO SYSTEMSJ

(5) The coil ground terminal (85) is connected to
the electromagnet in the relay. Check as follows:
(a) On YJ models, it is grounded at all times.
There should be continuity to ground at cavity for
relay terminal 85 at all times. If not, repair circuit
to ground as required.
(b) On XJ models, it is energized when the head-
lamp switch is on. There should be battery voltage
at cavity for relay terminal 85 with the headlamp
switch on. If not, repair circuit to headlamp switch
as required.
ANTENNA
The following four tests are used to diagnose the
antenna with an ohmmeter:
²mast to ground test (Test 1)
²tip-of-mast to tip-of-conductor test (Test 2)
²body ground to battery ground test (Test 3)
²body ground to coaxial shield test (Test 4).
Ohmmeter test lead connections for each test are
shown in Figure 3.
TEST 1
Test 1 determines if the antenna mast is insulated
from the base. Proceed as follows:
(1) Disconnect antenna cable lead from radio chas-
sis and isolate.
(2) Connect one ohmmeter lead to tip of antenna
mast and the other lead to the antenna base. Check
for continuity.
(3) There should be no continuity. If continuity is
found, replace defective or damaged antenna base
and cable assembly.
TEST 2
Test 2 checks the antenna for an open circuit as fol-
lows:
(1) Disconnect the antenna cable lead from the ra-
dio chassis.
(2) Connect one ohmmeter test lead to tip of an-
tenna mast. Connect remaining lead to tip of an-
tenna cable lead (the part inserted into the radio).
(3) Continuity should exist (ohmmeter should only
register a fraction of an ohm). High or infinite resis-
tance indicates damage to the base and cable assem-
bly. Replace if required.
TEST 3
Test 3 checks condition of the vehicle body ground
connection as follows:
(1) Connect one ohmmeter test lead to the vehicle
fender and the other lead to the battery negative
post.
(2) Resistance should be less than one ohm.
(3) If resistance is more than one ohm, check the
braided ground strap connected to the engine and ve-
hicle body for being loose, corroded, or damaged. Re-
pair as necessary.
TEST 4
Test 4 checks condition of the ground between the
antenna base and vehicle body as follows:
(1) Connect one ohmmeter test lead to the fender
and the other lead to the crimp on the coaxial an-
tenna cable shield.
(2) Resistance should be less then one ohm.
(3) If resistance is more then one ohm:
(a) On YJ models, replace the antenna base at-
taching screws with new cadmium plated screws.
(b) On XJ models, clean and/or tighten antenna
base to fender mounting hardware.
RADIO FREQUENCY INTERFERENCE
Inspect ground connections at:
²blower motor
²electric fuel pump
²generator
²ignition module
²wiper motor
²antenna coaxial ground
²radio ground
²body-to-engine ground strap (braided).
Clean, tighten or repair as required.
Also inspect the following secondary ignition sys-
tem components:
²spark plug wire routing and condition
²distributor cap and rotor
²ignition coil
²spark plugs.
Reroute spark plug wires or replace components as
required.

GENERAL INFORMATION
Following are general descriptions of the major
components in the XJ (Cherokee)/YJ (Wrangler)
model turn signal and hazard warning systems. Refer
to Group 8W - Wiring Diagrams for complete circuit
descriptions and diagrams.
TURN SIGNAL SYSTEM
With the ignition switch in the ON or ACCESSORY
position and the turn signal switch lever (YJ) or
multi-function switch control lever (XJ) moved up
(right turn) or down (left turn), the turn signal sys-
tem is activated.
When the turn signal system is activated, the se-
lected (right or left) turn signal indicator lamp, front
park/turn signal lamp and rear tail/stop/turn signal
lamp bulb filaments will flash. With the headlamp
switch in the OFF position, the turn and front side
marker lamps flash in unison. With the headlamp
switch in the ON position, the turn and front side
marker lamps flash alternately.
HAZARD WARNING SYSTEM
The hazard warning is activated by a switch button
located below the ignition lock cylinder (YJ) or on the
top of the steering column (XJ) between the steering
wheel and the instrument panel. The hazard warning
flasher (YJ) or combination flasher (XJ) receives bat-
tery feed at all times, and the system is functional
regardless of ignition switch position. The hazard
warning switch button is identified with a double
triangle. On YJ models, push the switch button in to
activate the hazard warning system and pull the
button out to turn system off. On XJ models, push in
on the switch button to latch the switch and activate
the hazard warning system, and push in on the
switch button again to unlatch the switch and turn
the system off.
When the hazard warning system is activated, all
(right and left) turn signal indicator, front park/turn
signal lamp and rear tail/stop/turn signal lamp bulb
filaments will flash.
TURN SIGNAL FLASHER (YJ ONLY)
The turn signal flasher is located in the fuseblock
module. It contains one fixed contact point and one
contact point attached to a flexible bimetal arm. The
contact points are normally closed. When a turn sig-
nal is activated, current flows through the flasher. As
current flows through the bimetal arm it heats and
flexes to pull the contact points open, stopping cur-
rent flow. As the bimetal arm cools it straightens,
until the contact points close and the cycle repeats.
The standard flasher is designed to handle the cur-
rent flow requirements of the factory installed light-
ing. If supplemental lighting is added to the turn
signal circuits such as when towing a trailer with
lights, the current flow through the flasher increases.
This causes the flash rate to increase. It is recom-
mended that the standard flasher be replaced with a
heavy-duty (hazard warning) flasher when supple-
mental lighting is added.
However, when a turn signal bulb fails with a stan-
dard flasher, the remaining bulbs in that circuit will
light, but not flash. This will give the driver an indi-
cation to check the turn signal bulbs. Because a
heavy-duty flasher has different internal circuitry, a
failed bulb will not prevent the remaining bulbs in
the circuit from flashing. Therefore, it is recom-
mended that an occasional visual inspection of exte-
rior turn signal lamp operation be performed when a
heavy-duty flasher is installed.
HAZARD WARNING FLASHER (YJ ONLY)
The hazard warning flasher is located in the fuse-
block module. The hazard warning flasher contains
two normally open contact points mounted to two
flexible arms. A bimetal strip is attached between the
two arms. When the hazard warning is activated,
current flows through the flasher. As the current
flows through the bimetal strip it heats and pulls the
flexible arms together until the contact points close,

GENERAL INFORMATION - XJ
Following are general descriptions of the major
components in the XJ (Cherokee) wiper and washer
systems. Refer to Group 8W - Wiring Diagrams for
complete circuit descriptions and diagrams.
WINDSHIELD WIPER SYSTEM
A two-speed wiper system is standard equipment
on all left-hand drive XJ models. An optional inter-
mittent wipe system is available. The intermittent
wipe system is standard equipment on all right-hand
drive XJ models. The two-speed wiper system allows
the driver to select from two wiper speeds. The inter-
mittent wipe system allows the driver to select from
two wiper speeds or an intermittent wipe feature
that allows a delay between wipes of 2 to 15 seconds.
Refer to the owner's manual for more information on
wiper system controls and operation.
The wipers will operate only when the ignition
switch is in the ACCESSORY or ON position. A cir-
cuit breaker near the fuseblock module protects the
circuitry of the wiper system on left-hand drive mod-
els. The circuit breaker is in the fuseblock module on
right-hand drive models.
WINDSHIELD WASHER SYSTEM
A electrically-operated windshield washer system is
standard equipment on all XJ models. The washers will
operate only when the ignition switch is in the ACCES-
SORY or ON position. A circuit breaker near the fuse-
block module protects the circuitry of the washer
system. Refer to the owner's manual for more informa-
tion on washer system controls and operation.
LIFTGATE WIPER/WASHER SYSTEM
A liftgate wiper/washer system is an available op-
tion on XJ models. The liftgate wiper is a fixed cycle
intermittent wipe system. A single switch on the in-
strument panel controls both the liftgate wiper and
washer functions. These systems will operate only
when the ignition switch is in the ON position. Fuse
1 in the fuseblock module protects the circuitry ofboth the liftgate wiper and washer. Refer to the own-
er's manual for more information on liftgate wiper/
washer system controls and operation.
WIPER ARMS, BLADES, AND ELEMENTS
All XJ models have two 18-inch windshield wiper
blades with replaceable rubber elements (squeegees).
Models with the liftgate wiper option use a single 12-
inch wiper blade with a replaceable rubber element
(squeegee).
Caution should be exercised to protect the rubber
squeegees from any petroleum-based cleaners or con-
taminants, which will rapidly deteriorate the squee-
gee rubber. If squeegees are damaged, worn or
contaminated they must be replaced.
Wiper squeegees exposed to the weather for a long
time tend to lose their wiping effectiveness. Periodic
cleaning of the squeegees is suggested to remove de-
posits of salt and road film. The wiper blades, arms
and windshield or liftgate glass should be cleaned
with a sponge or cloth and a mild detergent or non-
abrasive cleaner. If the squeegees continue to streak
or smear, they should be replaced.
The blades are mounted to spring-loaded wiper
arms. Spring tension of the wiper arms controls the
pressure applied to the blades on the glass. The
windshield wiper arms are attached by an integral
latch to the two wiper pivots on the cowl grille panel
at the base of the windshield. The liftgate wiper arm
is attached by an integral latch directly to the lift-
gate wiper motor output shaft on the liftgate panel.
The wiper arms and blades can not be adjusted or re-
paired. If faulty, they must be replaced.
WIPER LINKAGE AND PIVOTS
The wiper pivots are fastened to the cowl top panel
with screws beneath the cowl cover/grille panel. Each
pivot assembly can be replaced by removing the cowl
grille panel, unsnapping the linkage bushing(s) from
the pivot crank arm pins, and removing the mount-
ing screws.
JWIPER AND WASHER SYSTEMS 8K - 1

The two pivot cranks are joined by a connecting link,
and a drive link connects the motor crank to the drive
link near the left pivot. Pressed-in plastic bushings in
the ends of the links can be replaced if worn or dam-
aged.
WINDSHIELD WIPER MOTOR
The two-speed permanent magnet wiper motor has
an integral transmission and park switch. The motor
is mounted to the engine side of the cowl panel with
a reinforcement/stud plate and a rubber-isolated
mounting bracket. The wiper motor output shaft
passes through the cowl panel into the cowl plenum
area, where a crank arm attached to the output shaft
drives the wiper drive link.
Wiper speed is controlled by current flow to the ap-
propriate set of brushes. The wiper motor completes
its wipe cycle when the switch is turned OFF, and
parks the blades in the lowest portion of the wipe
pattern. The wiper motor assembly can not be re-
paired. If faulty, the entire motor assembly must be
replaced. The crank arm, mounting bracket, and re-
inforcement/stud plate are available for service.
LIFTGATE WIPER MOTOR
The liftgate wiper motor contains integral elec-
tronic controls and a transmission to provide three
operating modes:
²intermittent wipe with a fixed 5 to 8 second delay
between wipes
²constant wipe that operates when the liftgate
washer is operated
²a park mode that runs the motor until the wiper
blade reaches the park position after the liftgate
wiper switch or ignition switch is turned OFF.
The liftgate wiper motor can not be repaired. If
faulty, the entire assembly must be replaced.
WINDSHIELD WIPER/WASHER SWITCH
Controls for the windshield wiper and washer sys-
tems are contained in the multi-function switch con-
trol lever. The multi-function switch is mounted on
the left side of the steering column between the
steering wheel and the instrument panel. This switch
also controls many other functions. The multi-func-
tion switch can not be repaired. If any function of the
switch is faulty, the entire switch must be replaced.
LIFTGATE WIPER/WASHER SWITCH
The single two-function switch on the instrument
panel right of the steering column controls the lift-
gate wiper and washer functions. The rocker-type
switch features a detent in the WIPE position, but
only momentary contact in the WASH position. Both
the liftgate wiper and liftgate washer motors will op-
erate continuously for as long as the switch is held in
the WASH position. The switch can not be repaired;
if faulty, it must be replaced.
INTERMITTENT WIPE MODULE
In addition to low and high speed, the optional inter-
mittent wipe system has a delay mode. The delay mode
has a range of 2 to 15 seconds. The length of the delay
is selected with a variable resistor in the wiper (multi-
function) switch and is accomplished by electronic cir-
cuitry within the intermittent wipe module. If the
washer knob is depressed while the wiper (multi-func-
tion) switch is in the OFF position, the intermittent
wipe module will operate the wiper motor for approxi-
mately 2 wipes and automatically turn the motor off.
The intermittent wipe module is mounted to the
lower instrument panel, behind the knee blocker and
near the steering column with a hook and loop fas-
tener patch. The module can not be repaired.
WINDSHIELD WASHER NOZZLES
The two fluidic washer nozzles are riveted into
openings in the cowl grille panel below the wind-
shield and are not adjustable. Washer fluid is fed to
the nozzles through hoses clipped to the underside of
the cowl grille panel. The nozzles can not be repaired
and, if faulty, should be replaced.
LIFTGATE WASHER NOZZLE
The single liftgate washer nozzle snaps into place
on the liftgate wiper arm. Washer fluid is fed to the
nozzle from the washer reservoir in the engine com-
partment. A liftgate washer hose system is routed
through the body of the vehicle with the body wiring
harness from the reservoir to the liftgate. The fluid
passes through a nipple on the liftgate wiper motor
output shaft bezel to a hose clipped to the underside
of the wiper arm. The nozzle can not be repaired and,
if faulty, should be replaced.
WASHER RESERVOIR
The washer solvent reservoir is mounted to the left
front inner fender shield near the cowl panel. The
same reservoir is used for both the standard front
and optional liftgate washer systems. It also has a
provision for a low washer fluid level sensor. Refer to
Group 8E - Instrument Panel and Gauges for diagno-
sis and service of the sensor. The reservoir and filler
cap are available for service.
WASHER PUMPS
The washer pump and motor are press-fit into a
rubber grommet near the bottom of the washer res-
ervoir. Vehicles with the optional liftgate wiper/
washer system have two pumps installed in the
single reservoir. A permanently lubricated and sealed
motor is coupled to a rotor-type pump. Washer fluid
is gravity fed from the reservoir to the pump. The
pump then pressurizes the fluid and forces it through
the plumbing to the nozzles when the motor is ener-
gized. The pump and motor can not be repaired. If
faulty, the entire assembly must be replaced.
