HEADLAMP LEVELING
SWITCH - EXPORT
DESCRIPTION
Some vehicles are equipped with a remote head-
lamp leveling system. This system allows the driver
to adjust the vertical headlamp aim from the interior
of the vehicle to compensate for passenger or cargo
load.
The headlamp leveling switch is located next to the
headlamp switch on the instrument panel (Fig. 16).
If the headlamp leveling switch is faulty or damaged,
the headlamp switch must be replaced.
DIAGNOSIS AND TESTING - HEADLAMP
LEVELING SWITCH - EXPORT
The headlamp leveling switch is located next to the
headlamp switch on the instrument panel. (Refer to 8
- ELECTRICAL/LAMPS/LIGHTING - EXTERIOR/
HEADLAMP SWITCH - DIAGNOSIS AND TEST-
ING) for diagnosis of the headlamp leveling switch. If
the headlamp leveling switch is faulty, the headlamp
switch must be replaced.

DIAGNOSIS AND TESTING
DIAGNOSIS AND TESTING - HEADLAMP
SWITCH
Using a Digital Multi-meter, perform the HEAD-
LAMP SWITCH CONTINUITY test and refer to (Fig.

HEADLAMP UNIT
STANDARD PROCEDURE
STANDARD PROCEDURE - HEADLAMP UNIT
ALIGNMENT
HEADLAMP UNIT ALIGNMENT PREPARATION
(1) Verify headlamp dimmer switch and high beam
indicator operation.
(2) Inspect and correct damaged or defective com-
ponents that could interfere with proper headlamp
alignment.
(3) Verify proper tire inflation.
(4) Clean headlamp lenses.
(5) Verify that luggage area is loaded as the vehi-
cle is routinely used.(6) Vehicles equipped with automatic load leveling
suspension should be driven normally for approxi-
mately 5 km (3 miles) before attempting a proper
headlamp unit alignment.
(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 7.62 meters (25 ft.) away from front
of headlamp lens (Fig. 19).
(2) If necessary, tape a line on the floor 7.62
meters (25 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   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. 20). To adjust headlamp verti-
cal alignment, rotate adjustment screw to achieve the
specified low beam cut-off location.
STANDARD PROCEDURE - HEADLAMP UNIT

(4) Clean headlamp lenses.
(5) Verify that luggage area is loaded as the vehi-
cle is routinely used.

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. 21).
(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 thealignment screen (with tape). Use this line for

HEADLAMP UNIT ADJUSTMENT
The low beam headlamp will project on the screen
upper edge of the beam (cut-off) at the horizontal
lamp cut-off line   20 mm (0.75 in.). The high beam
pattern should be correct when the low beams are
aligned properly (Fig. 22). To adjust headlamp align-
ment, rotate adjustment screws to achieve the speci-
fied low beam cut-off location.

MULTI-FUNCTION SWITCH
DESCRIPTION - TURN SIGNAL SYSTEM
The turn signals are actuated with a lever on
Multi-Function Switch, located on the left side of the
steering wheel. The signals are automatically turned
off by a canceling cam (two lobes molded to the clock
spring mechanism). The cam comes in contact with
the cancel actuator on the turn signal (multi-func-
tion) switch assembly. Either cam lobe, pushing on
the cancel actuator, returns the switch to the OFF
position. The multi-function switch is a resistive
MUX switch that feeds inputs to the BCM.
OPERATION - TURN SIGNAL SYSTEM
Lane change signaling is actuated by applying par-
tial turn signal stalk movement toward the direction
desired until the indicator lamps flashes in the
instrument cluster. When the switch stalk is released
the stalk will spring back into the neutral position
turning OFF the turn signal.
With the ignition switch ON and the turn signal
switch stalk actuated left or right, current flows
through the:
²Multi-function switch
²Body Control Module
²Integrated Power Module (IPM)
²Turn indicator lamp
²Front and rear turn signal bulbs.
A chime will sound after the vehicle has traveled a
distance of approximately 1.0 mile and a speed of 15
mph, with the turn signal ON.
DIAGNOSIS AND TESTING - MULTI-FUNCTION
SWITCH
To test turn signal, headlamp beam select and opti-
cal horn portion of the multi-function switch:(1) Remove the multi-function switch, refer to
Electrical, Lamps/Lighting - Exterior, Multi-Function
Switch, Removal, and Installation.
(2) Using an ohmmeter check the resistance read-
ings between multi-function switch pins. Refer to
Wiring Diagrams for proper pin numbers and the
MULTI-FUNCTION SWITCH RESISTANCE table.
