FOG LAMP SERVICE INFORMATION
Fog lamps can be operatedONLYwhen the head-
lamps are on LOW beam. If the headlamps are
switched to HIGH beam, the fog lamps will not oper-
ate.
Also, the fog lamps ON display on the switch will:
²be illuminated when the headlamps are switched
to LOW beam; and
²be extinguished when the headlamps are switched
to HIGH beam.
FOG LAMP TROUBLE DIAGNOSIS
ONE FOG LAMP INOPERATIVE
(1) Place the headlamp switch in the full ON posi-
tion, the dimmer switch in the LOW beam position
and the fog lamp switch in the ON position.
(2) Disconnect the applicable fog lamp wire har-
ness connector (Fig. 33).
(3) Measure the resistance between the lamp con-
nector terminals. The ohmmeter should indicate zero
ohms. If not OK, replace the bulb.
(4) Measure the resistance between the wire har-
ness connector ground terminal and vehicle body
ground. The ohmmeter should indicate zero ohms. If
not OK, repair the open circuit in the wire harness
to vehicle body ground.
(5) Measure the voltage between the wire harness
connector voltage supply terminal and body ground.
The voltmeter should indicate battery voltage. If not
OK, repair the open circuit in the wire harness that
leads to the source of battery voltage.
BOTH FOG LAMPS INOPERATIVE
(1) Place headlamp switch in the full ON position.The dimmer switch in the LOW beam position. The
fog lamp switch in the ON position.
(2) Measure the voltage between the fog lamp
switch wire harness connector terminal B and vehi-
cle body ground. The voltmeter should indicate bat-
tery voltage. If not OK, repair the open circuit in the
wire harness that leads to the headlamp dimmer
switch circuit.
(3) Measure the voltage between the fog lamp
switch connector terminal C and vehicle body
ground. The voltmeter should indicate battery volt-
age. If not OK, replace the fog lamp switch.
(4) Measure the voltage between the fog lamp re-
lay connector terminal 1 and vehicle body ground.
The voltmeter should indicate battery voltage. If not
OK, repair the open circuit in the wire harness that
leads to the power distribution center/PDC.
(5) Measure the voltage between the fog lamp re-
lay connector terminal 5 and vehicle body ground.
The voltmeter should indicate battery voltage. If not
OK, repair the open circuit in the wire harness that
leads to the fog lamp switch.
(6) Measure the voltage between the fog lamp re-
lay connector terminal 2 and vehicle body ground.
The voltmeter should indicate battery voltage. If not
OK, repair the open circuit in the wire harness that
leads to vehicle body ground.
(7) Measure the voltage between the fog lamp re-
lay connector terminal 4 and vehicle body ground.
The voltmeter should indicate battery voltage. If not
OK, replace the relay.
FOG LAMP BEAM ADJUSTMENT
Use an ``aiming'' screen for fog lamp beam aim ad-
justment.
PREPARATION
Prior to adjustment, the following preparation is
required.

(1) Position the vehicle in dark area with a level
floor and with a screen (wall) that has a white sur-
face.
(2) Mark a reference line on the floor 7.62 meters
(25 feet) away from and parallel to the ``aiming''
screen/wall.
(3) Position vehicle with the fog lamps located di-
rectly above the 7.62-meters (25-feet) reference line.
(4) Equalize all the tire pressures.
(5) Rock the vehicle from side to side to stabilize
the springs and shock absorbers.
(6) Refer to Figure 34. Use tape to attach a vehicle
centerline on the screen/wall. Ensure that it is
aligned with and represents the centerline of the ve-
hicle.
(7) Measure the distance between the vehicle fog
lamp centers. Divide this distance by two. Measure
the one/half distance outward from each side of the
vehicle centerline. Use tape to attach the right and
left fog lamp vertical centerline on the screen/wall.
(8) Measure the distance from the center of each
fog lamp to the floor.
(9) Measure the lamp-to-floor distance upward
from the floor at each lamp vertical centerline. Use
tape to attach the lamp horizontal centerline on the
screen/wall.
BEAM ADJUSTMENT
(1) Loosen the fog lamp attaching hardware at the
support bracket.
(2) Place the headlamp and fog lamp switches in
the ON position.
(3) Ensure that the headlamp dimmer switch is in
the LOW beam position.
(4) Adjust the fog lamp beams according to the fol-
lowing guidelines:
²a properly adjusted fog lamp (up/down adjustment)
will project a beam pattern on the screen similar to
the pattern depicted in Figure 28; and
²each fog lamp should be centered (left/right adjust-
ment) on the screen left/right vertical center line.
(5) Tighten the fog lamp support bracket hard-
ware.

DAYTIME RUNNING LIGHTS (CANADA ONLY)
SERVICE INFORMATION
The Daytime Running Lights (Headlamps) System
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.
DRL MODULE REPLACEMENT

The Daytime Running Lights (DRL) module is lo-
cated on the right fender inner panel adjacent to the
dash panel (Fig. 45).
