FOG LAMP
DIAGNOSIS AND TESTING - FOG LAMP
When a vehicle experiences problems with the fog
lamp system, verify the condition of the battery con-
nections, fuses, charging system, fog lamp bulbs, wire
connectors, relay, high beam switch, and headlamp
switch. Refer to the appropriate wiring information.
Each vehicle is equipped with various lamp assem-
blies. A good ground is necessary for proper lighting
operation. Grounding is provided by the lamp socket
when it comes in contact with the metal body, or
through a separate ground wire.
When changing lamp bulbs check the socket for
corrosion. If corrosion is present, clean it with a wire
brush.
When it is necessary to remove components to ser-
vice another, it should not be necessary to apply
excessive force or bend a component to remove it.
Before damaging a trim component, verify hidden
fasteners or captured edges are not holding the com-
ponent in place.

HEADLAMP ADJUSTMENT
The low beam headlamp will project on the screen
upper edge of the beam (cut-off) at the horizontal
lamp centerline   50 mm (2 in.). Horizontal aim is
preset and can not be adjusted. The high beam pat-
tern should be correct when the low beams are
aligned properly (Fig. 19). To adjust headlamp verti-
cal alignment, rotate adjustment screw to achieve the
specified low beam cut-off location.
STANDARD PROCEDURE - HEADLAMP UNIT
ALIGNMENT - EXPORT
HEADLAMP UNIT ALIGNMENT PREPARATION
(1) Verify headlamp dimmer switch and high beam
indicator operation.
(2) Verify that the headlamp leveling switch is in
the ª0º position.
(3) Inspect and correct damaged or defective com-
ponents that could interfere with proper headlamp
alignment.(4) Verify proper tire inflation.
(5) Clean headlamp lenses.
(6) Verify that luggage area is loaded as the vehi-
cle is routinely used.
(7) Fuel tank should be FULL. Add 2.94 kg (6.5
lbs.) of weight over the fuel tank for each estimated
gallon of missing fuel.
ALIGNMENT SCREEN PREPARATION
(1) Position vehicle on a level surface perpendicu-
lar to a flat wall 10 meters (32.8 ft.) away from front
of headlamp lens (Fig. 20).
(2) If necessary, tape a line on the floor 10 meters
(32.8 ft.) away from and parallel to the wall.
(3) Rock vehicle side-to-side three times and allow
suspension to stabilize.
(4) Jounce front suspension three times by pushing
downward on front bumper and releasing.
(5) Measure the distance from the center of head-
lamp lens to the floor. Transfer measurement to the
alignment screen (with tape). Use this line for
up/down adjustment reference.
HEADLAMP UNIT ADJUSTMENT
The low beam headlamp will project on the screen
upper edge of the beam (cut-off) at the horizontal
lamp centerline   20 mm (0.75 in.). The high beam
pattern should be correct when the low beams are
aligned properly (Fig. 21). To adjust headlamp align-
ment, rotate adjustment screws to achieve the speci-
fied low beam cut-off location.
REMOVAL
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the three retaining screws (Fig. 22).
(3) Disconnect the wiring harness from the bulbs
(Fig. 23).
(4) Remove wire harness retainer from back of
headlamp unit.
(5) Remove the headlamp unit.
