DESCRIPTION AND OPERATION

HEADLAMP LEVELING MOTOR

DESCRIPTION
Vehicles equipped with a remote headlamp leveling system use two leveling motors attached to each headlamp mounting bracket. They are located just behind the headlamp assemblies and must be accessed from underneath the vehicle.
LAMP SERVICE............................ 8
BULB APPLICATION ....................... 11
DIAGNOSIS AND TESTING ..................2
OPERATION
This system allows the driver to adjust the vertical headlamp aim from the interior of the vehicle to com­pensate for passenger or cargo load. A headlamp lev­eling switch is located in the instrument panel and controls the headlamp leveling motor function.
DIAGNOSIS AND TESTING

DIAGNOSTIC PROCEDURES

When a vehicle experiences problems with the headlamp system, verify the condition of the battery connections, fuses, charging system, headlamp bulbs, wire connectors, relay, high beam switch, dimmer switch, and headlamp switch. Refer to Group 8W, Wiring Diagrams for component locations and circuit information.

SERVICE PROCEDURES

HEADLAMP ALIGNMENT PREPARATION........3
SERVICE PROCEDURES

HEADLAMP ALIGNMENT PREPARATION

(1) Verify headlamp are on low beam setting. (2) Verify that the headlamp leveling switch is in
the “0” position.
(3) Inspect and correct damaged or defective com­ponents 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 vehi­cle 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.

ADJUSTMENTS

HEADLAMP/FOG LAMP ADJUSTMENT USING ALIGNMENT SCREEN

ALIGNMENT SCREEN PREPARATION
(1) Position vehicle on a level surface perpendicu­lar to a flat wall 10 meters (32.8 ft.) away from front of headlamp lens (Fig. 1).
(2) Place 75 kg in the driver’s seat to simulate the ride height of the vehicle when driven.
(3) If necessary, tape a line on the floor 10 meters (32.8 ft) away from and parallel to the wall.
(4) From the floor up 1.27 meters (5 ft), tape a line on the wall at the centerline of the vehicle. Sight along the centerline of the vehicle (from rear of vehi­cle forward) to verify accuracy of the line placement.
ADJUSTMENTS
HEADLAMP/FOG LAMPADJUSTMENT USING
ALIGNMENT SCREEN ....................3
(5) Rock vehicle side-to-side three times and allow
suspension to stabilize.
(6) Jounce front suspension three times by pushing
downward on front bumper and releasing.
(7) Measure the distance from the center of head­lamp lens to the floor. Transfer measurement to the alignment screen (with tape). Use this line for up/down adjustment reference.
(8) Place a tape line 130 mm below and parallel to the center of headlamp line.
(9) Measure distance from the centerline of the vehicle to the center of each headlamp being aligned. Transfer measurements to screen (with tape) to each side of vehicle centerline. Use these lines for left/ right adjustment reference.
HEADLAMP ADJUSTMENT
A properly aimed low beam headlamp will project a high intensity light pattern on the screen with the horizontal cut-off line aligned with the tape line 130 mm (5.12 in.) below the headlamp centerline (Fig. 1). The intersection of the horizontal and 15 degree cut­off lines in the projected pattern should align to the intersection of the headlamp centerline vertical tape line and the tape line 130 mm (5.12 in.) below the headlamp horizontal centerline. The high beams on a vehicle with aero headlamps cannot be aligned. The high beam pattern should be correct when the low beams are aligned properly.
To adjust headlamp alignment, rotate alignment screws (Fig. 2) to achieve the specified low beam hot spot pattern.

FOG LAMP ALIGNMENT
Prepare an alignment screen. Refer to the Align­ment Screen Preparation paragraph in this section. A properly aligned fog lamp will project a pattern on the alignment screen 200 mm (8 in.) below the fog lamp centerline and straight ahead (Fig. 3). To improve visual interpretation of the fog lamp pattern on the alignment screen, disable the headlamps by disengaging the wire connectors from the headlamp bulbs.
To adjust fog lamp alignment, rotate alignment screws (Fig. 4) to achieve the specified pattern.
