IGNITION-OFF DRAW
GENERAL INFORMATION
Ignition-Off Draw (IOD) refers to power being
drained from the battery with the ignition switch
turned OFF. A normal vehicle electrical system will
draw from 5 to 20 milliamps (0.005 - 0.020 amps).
This is with the ignition switch in the OFF position,
and all non-ignition controlled circuits in proper
working order. The 20 milliamps are needed to sup-
ply PCM memory, digital clock memory, and electron-
ically-tuned radio memory.
A vehicle that has not been operated for approxi-
mately 20 days, may discharge the battery to an in-
adequate level. When a vehicle will not be used for
20 days or more (stored), remove the IOD fuse in the
Power Distribution Center (PDC). This will reduce
battery discharging.
Excessive battery drain can be caused by:
²electrical items left on
²faulty or improperly adjusted switches
²internally shorted generator
²intermittent shorts in the wiring.
If the IOD is over 20 milliamps, the problem must
be found and corrected before replacing a battery. In
most cases, the battery can be charged and returned
to service.
DIAGNOSIS
Testing for high-amperage IOD must be per-
formed first to prevent damage to most milli-
amp meters.
(1) Verify that all electrical accessories are off.
Turn off all lamps, remove ignition key, and close all
doors. If the vehicle is equipped with illuminated en-
try or electronically-tuned radio, allow the systems to
automatically shut off (time out). This may take up
to 3 minutes.
(2) Determine that the underhood lamp is operat-
ing properly, then disconnect or remove bulb.
(3) Disconnect negative cable from battery.
(4) Connect a typical 12-volt test lamp (low-watt-
age bulb) between the negative cable clamp and the
battery negative terminal. Make sure that the doors
remain closed so that illuminated entry is not acti-
vated.The test lamp may light brightly for up to 3 min-
utes, or may not light at all, depending upon the ve-
hicle's electrical equipment. The term brightly, as
used throughout the following tests, implies the
brightness of the test lamp will be the same as if it
were connected across the battery.
The test lamp must be securely clamped to the neg-
ative cable clamp and battery negative terminal. If
the test lamp becomes disconnected during any part
of the IOD test, the electronic timer function will be
activated and all tests must be repeated.
(5) After 3 minutes the test lamp should turn off
or be dimly lit, depending upon the vehicle's electri-
cal equipment. If the test lamp remains brightly lit,
do not disconnect it. Remove each fuse or circuit
breaker (refer to Group 8W - Wiring Diagrams) until
test lamp is either off or dimly lit. This will isolate
each circuit and identify the source of the high-am-
perage draw.
If the test lamp is still brightly lit after disconnect-
ing each fuse and circuit breaker, disconnect the wir-
ing harness from the generator. If test lamp now
turns off or is dimly lit, see Charging System in this
group to diagnose faulty generator. Do not disconnect
the test lamp.
After high-amperage IOD has been corrected, low-
amperage IOD may be checked. It is now safe to in-
stall a milliamp meter to check for low- amperage
IOD.
(6) With test lamp still connected securely, clamp a
milliamp meter between battery negative terminal
and negative cable clamp.
Do not open any doors or turn on any electri-
cal accessories with the test lamp disconnected
or the milliamp meter may be damaged.
(7) Disconnect test lamp. Observe milliamp meter.
The current draw should not exceed 0.020 amp. If
draw exceeds 20 milliamps, isolate each circuit by re-
moving circuit breakers and fuses. The milliamp
meter reading will drop when the source of the draw
is disconnected. Repair this circuit as necessary,
whether a wiring short, incorrect switch adjustment
or a component failure is found.

GENERAL INFORMATION
An overhead console featuring an electronic com-
pass and thermometer is an available option for XJ
(Cherokee) models. Following are general descrip-
tions of major components used in the overhead con-
sole. Refer to Group 8W - Wiring Diagrams for
complete circuit descriptions and diagrams.
COMPASS
The compass will display the direction in which the
vehicle is pointed using the eight major compass
headings (Examples: north is N, northeast is NE). It
does not display the headings in actual degrees. The
display is turned on or off using the COMP/TEMP
button to the left of the display.
The self-calibrating compass unit requires no ad-
justing in normal use. The only calibration that may
prove necessary is to drive the vehicle in 3 complete
circles, on level ground, in not less than 48 seconds.
This will reorient the unit to its vehicle.
The unit also will compensate for magnetism the
body of the vehicle may acquire during normal use.
However, avoid placing anything magnetic directly on
the roof of the vehicle. Magnetic mounts for an an-
tenna, a repair order hat or a funeral procession flag
can exceed the compensating ability of the compass
unit if placed on the roof panel. Magnetic bit drivers
used on the fasteners that hold the assembly to the
roof header can also affect compass operation.
If the vehicle roof should become magnetized, the
demagnetizing and calibration procedures may be re-
quired to restore proper operation.
THERMOMETER
The thermometer displays the outside ambient
temperature. The temperature displayed can be
changed from Fahrenheit to Celsius using the US/
METRIC button. The displayed temperature is not
an instant reading of conditions, but an average tem-
perature. It may take the unit several minutes to re-
act to a major temperature change such as driving
out of a heated garage into winter temperatures.
When the ignition switch is turned OFF, the lastdisplayed temperature reading stays in memory.
When the ignition switch is turned ON again, the
thermometer will display the memory temperature
for one minute; then update the display to the cur-
rent average temperature reading within five min-
utes.
READING AND COURTESY LAMPS
All reading and courtesy lamps in the overhead
console are activated by the door jamb switches.
When all doors and the liftgate are closed, the lamps
can be individually activated by depressing the corre-
sponding lens. When a door and/or the liftgate is
open, depressing the lamp lens switches will not turn
the lamps off. Refer to Group 8L - Lamps, for diag-
nosis and service of these lamps.
KEYLESS ENTRY RECEIVER
The overhead console houses the keyless entry re-
ceiver. Refer to Group 8P - Power Locks, for diagno-
sis and service of this component.
REMOTE GARAGE DOOR OPENER STORAGE
A compartment in the overhead console is designed
to hold most remote garage door opener transmitters.
The transmitter is mounted within the compartment
with an adhesive-backed hook and loop fastener
patch. Then one to three pegs are selected and
mounted on a post on the inside of the storage com-
partment door. The pegs may be stacked, if neces-
sary. The peg(s) selected must be long enough to
activate the button of the transmitter each time the
storage compartment door is depressed.
SUNGLASSES STORAGE
A flocked storage compartment for sunglasses is in-
cluded in the overhead console. This compartment
features a push/push-type latch and a viscous damp-
ening system for a fluid opening motion.

GENERAL INFORMATION
Following are general descriptions of major compo-
nents used in XJ (Cherokee)/YJ (Wrangler) audio sys-
tems. Refer to Group 8W - Wiring Diagrams for
complete circuit descriptions and diagrams.
RADIOS
Radio options for the XJ and YJ models include an
AM/FM stereo or an AM/FM stereo/cassette receiver.
Both units are Electronically-Tuned Radios (ETR)
and include a clock function. For more information
on radio features, setting procedures, and control
functions refer to the owner's manual.
IN-LINE FUSE
Each radio receives fused battery feed when the ig-
nition switch is in the ON or ACCESSORY position.
There is an additional in-line fuse in the back of the
radio chassis. The in-line fuse (Fig. 1) will blow to
protect the vehicle electrical system in the event of
internal radio failure.
IGNITION-OFF DRAW FUSE
All vehicles are equipped with an Ignition-Off
Draw (IOD) fuse that is removed when the vehicle is
shipped from the factory. This fuse feeds various ac-
cessories that require current when the ignition
switch is in the OFF position, including the clock and
radio station preset memory functions. The fuse is re-
moved to prevent battery discharge during vehicle
storage.The IOD fuse should be checked if the radio station
preset memory or clock functions are erratic or inop-
erative. The IOD fuse is located in the Power Distri-
bution Center (PDC). Refer to underside of PDC
cover for IOD fuse identification.
RADIO ILLUMINATION RELAY
All radios are connected to a radio illumination re-
lay. The relay controls the source of battery feed for
radio/clock display illumination.
When the park and headlamp switch is in the OFF
position, the radio illumination relay remains de-en-
ergized. The radio/clock display receives full battery
voltage through the normally closed contacts of the
relay. This results in the radio/clock display being il-
luminated at full brightness for easier visibility in
daylight.
When the park and headlamp switch is in the ON
position, the radio illumination relay coil is ener-
gized. With the relay coil energized, the normally
closed contacts of the relay open, and the normally
open contacts of the relay close. This causes the ra-
dio/clock display to receive battery feed through the
instrument panel dimmer switch. The display illumi-
nation brightness can now be adjusted with other
panel lamps for night visibility.
SPEAKERS
Speaker system options include two, four or six (XJ
only) speaker locations. On XJ model two-speaker
systems, one speaker is located in each front door.
Four-speaker systems add one speaker at each end of
a rear-mounted overhead sound bar. The premium
six-speaker option upgrades all the speakers in the
above locations, and adds one tweeter at each end of
the lower instrument panel.
On YJ model two-speaker systems, one speaker is
located at each end of the instrument panel. Four-
speaker systems add one speaker at each end of a
rear-mounted overhead sound bar.

GENERAL INFORMATION
Power locks are optional equipment on XJ (Chero-
kee) models. Power windows and the keyless entry
system are included on vehicles equipped with the
power lock option. All doors and the liftgate can be
locked and unlocked electrically by operating the
switch on either front door panel, or by operating the
lock and unlock buttons of the remote keyless entry
transmitter. The power lock and keyless entry sys-
tems operate with battery power supplied indepen-
dent of the ignition switch.
Following are general descriptions of the major
components in the power lock system. Refer to Group
8W - Wiring Diagrams for complete circuit descrip-
tions and diagrams. Refer to the owner's manual for
more information on the features and use of these
systems.
POWER LOCK SWITCH
The power locks are controlled by a two-way switch
mounted on the trim panel of each front door. The
switch controls battery feed to the lock and unlock
relays. The door lock switches can not be repaired. If
faulty, the entire switch must be replaced.
POWER LOCK/UNLOCK RELAYS
The power lock and unlock relays are located in the
relay center. The relay center is located on the lower
instrument panel reinforcement behind the lower in-
strument panel and just right of the steering column.
The relays respond to inputs from the power lock
switches and the keyless entry module by sending
the correct battery and ground feeds to the lock mo-
tors. The lock and unlock relays can not be repaired.
If faulty, they must be replaced.
POWER LOCK MOTOR
The locks are actuated by a reversible motor
mounted within each door. The motor direction iscontrolled by the battery and ground feeds from the
power lock/unlock relays. The motor can not be re-
paired. If faulty, the entire motor must be replaced.
KEYLESS ENTRY TRANSMITTER
The keyless entry transmitter is equipped with two
buttons labeled Lock and Unlock. It is also designed
to serve as a key fob and is equipped with a key ring.
Each transmitter has a different vehicle access code,
which must be programmed into the memory of the
keyless entry module in the vehicle in order to oper-
ate the locks. The operating range of the infrared
transmitter signal is up to 4.75 meters (15 feet) from
the receiver.
The transmitter operates on two CR1616 3-volt (or
equivalent) batteries. Typical battery life is from one
to two years.
KEYLESS ENTRY MODULE
The keyless entry module is mounted in a housing
on the headliner near the windshield between the
sunvisors, or inside and towards the rear of the over-
head console (if equipped). This module contains the
keyless entry receiver and program logic for the key-
less entry system.
The keyless entry module has a memory function
to retain the vehicle access code of at least one, and
up to four transmitters. The module receives input
from the remote keyless entry transmitter. In re-
sponse to that input, it is programmed to control out-
puts to the lock and unlock relays. The module can
not be repaired and, if faulty, must be replaced.
