SERVICE INFORMATION
Exterior lamp circuits are comprised of the head-
lamp circuit, fog lamp circuit, and tail/side marker/
park lamp circuit. Battery voltage is controlled by
both the headlamp ON/OFF switch and headlamp
dimmer switch.
The dimmer switch functions as a fog lamp switch.
Voltage is applied to the fog lamp switch only when
the dimmer switch is in the low beam position.
HEADLAMP TROUBLE DIAGNOSISÐXJ VEHICLES
LOW AND HIGH BEAM INOPERATIVE BOTH
HEADLAMPS
(1) Place the headlamp switch in the ON position.
(2) Test the 40 amp fuse for continuity. If bad, re-
place fuse.
(3) Insert the test probe into terminal 5 of the
front lamp wire harness connector. Measure the re-
sistance from terminal 5 to body ground. The ohm-
meter should indicate zero ohms. If not OK, repair
the open circuit in the harness to body ground.(4) Disconnect the front lamp wire connector. Mea-
sure resistance between connector terminals 5 and 2.
Next measure between terminal 5 and 7. The ohm-
meter should indicate zero ohms for both measure-
ments. If not OK, replace the headlamp bulbs.
(5) Measure the voltage between the dimmer
switch wire connector terminal 2 and body ground.
The voltmeter should indicate battery voltage. If not
OK, continue with the next step.
The dimmer switch is integral with the turn
signal and is located on the steering column.
The dimmer switch switches the headlamp beam
when the turn signal lever is pulled rearward.
(6) Disconnect the dimmer switch wire connector
and place the headlamp switch in the OFF position.
Measure the resistance from terminal 2 to vehicle
body ground. The ohmmeter should indicate infinite
resistance. If OK, replace the headlamp switch and
continue with the next step. If not OK, repair the
short circuit in the wire harness that leads to termi-
nal 2.

(3) Move vehicle with the headlamps located di-
rectly above the 7.62-meters (25-feet) reference line.
(4) Equalize all the tire pressures.
(5) Rock vehicle from side to side to stabilize the
springs and shock absorbers.
(6) Use tape to attach a vehicle centerline on the
screen/wall (6). Ensure that it is aligned with and
represents the centerline of the vehicle.
(7) Measure distance between the vehicle head-
lamp centers. Divide this distance by two. Measure
the one/half distance outward from each side of the
vehicle centerline (6). Use tape to attach the right
and left lamp vertical centerline (4 and 5) on the
screen/wall (6).
(8) Measure the distance from the center of each
headlamp to the floor.
(9) Measure the lamp-to-floor distance upward
from the floor at each lamp vertical centerline (4 and
5). Use tape to attach the lamp horizontal centerline
(3) on the screen/wall.
ADJUSTMENT
(1) Remove screws and both headlamp bezels.
(2) Clean front of the headlamps.
(3) Place headlamps on LOW beam.
(4) Cover front of the headlamp that is not being
adjusted.
(5) Turn vertical adjustment screw until the head-
lamp beam pattern on screen/wall is similar to the
pattern depicted in Figure 6.
When using a headlamp aiming screen:
²adjust the headlamps so that the beam horizontal
position is at 0; and
²adjust the beam vertical position is 25 mm (1 in)
downward from the lamp horizontal centerline.(6) Rotate the horizontal adjustment screw until
the headlamp beam pattern on the aiming screen/
wall similar to the pattern in Figure 6.
(7) Cover front of the headlamp that has been ad-
justed and adjust the other headlamp beam as in-
structed above.
(8) Install headlamp bezels. Tighten the screws se-
curely.

is installed on vehicles manufactured for sale in Can-
ada only. The headlamps are illuminated when the
ignition switch is turned to the ON position. The
DRL module receives a vehicle-moving signal from
the vehicle speed sensor. This provides a constant
headlamps-oncondition as long as the vehicle is
moving. The lamps are illuminated at less than 50
percent of normal intensity.

Voltage is applied at all times via the dome lamp
fuse to each of the interior lamp bulbs. The interior
lamp bulbs illuminate when they are connected to
body ground via the switch:
²headlamp switch,
²glove box switch,
²door pillar switch, and
²liftgate switch (if the cargo lamp is ON.)
If equipped with Security Alarm Module, refer to
Group 8QÐVehicle Theft Security System.
YJ VEHICLES
The dome/cargo and courtesy lamps are controlled
via ON/OFF switches. The ON/OFF switches are in
the lamp ground circuits. Voltage via the dome/cour-
tesy lamp fuse is applied directly to the lamp bulbs.
When either door is opened, the door pillar switch
contacts close and provide a direct path to vehicle
body ground.

terminals. The ohmmeter should indicate zero ohms.
If not, replace the bulb.
(2) Measure the voltage between the voltage side
of the bulb holder and vehicle body ground. The volt-
meter should indicate battery voltage. If not, repair
the open circuit in the wire harness to the splice.
LAMPS INOPERATIVE WITH ONE OR MORE
DOORS OPENED
(1) Remove the inoperative switch from the door
pillar and connect the switch wire directly to ground.
