GENERAL INFORMATION
HEADLAMP ALIGNMENT
Headlamps can be aligned using the screen method provided in this section. Alignment Tool C-4466-A or equivalent can also be used. Refer to instructions provided with the tool for proper procedures. The preferred headlamp alignment setting is 0 for the left/right adjustment and 1( down for the up/down adjustment.
SERVICE PROCEDURES
HEADLAMP ALIGNMENT PREPARATION
(1) Verify headlamp dimmer switch and high beam indicator operation.
(2) Correct defective components that could hinder proper headlamp alignment.
(3) Verify proper tire inflation. (4) Clean headlamp lenses. (5) Verify that luggage area is not heavily loaded. (6) 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 perpendicular to a flat wall 7.62 meters (25 ft) away from front of headlamp lens (Fig. 1).
(2) If necessary, tape a line on the floor 7.62 meters (25 ft) away from and parallel to the wall.
(3) Measure from the floor up 1.27 meters (5 ft) and tape a line on the wall at the centerline of the page page

(4) Rock vehicle side-to-side three times to allow suspension to stabilize.
(5) Jounce front suspension three times by pushing downward on front bumper and releasing.
(6) 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.
(7) 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 USING ALIGNMENT SCREEN
A properly aimed low beam will project the top edge of high intensity pattern on the screen from 50 mm (2 in.) above to 50 mm (2 in.) below headlamp centerline. The side-to-side left edge of high intensity pattern should be from 50 mm (2 in.) left to 50 mm (2 in.) right of headlamp centerline (Fig. 1). The preferred headlamp alignment is 0 for the left/ right adjustment and 1( down for the up/down adjustment. 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 aim, rotate alignment screws (Fig. 2).
Fig. 1 Headlamp Alignment Screen—Typical
FOG LAMP ADJUSTMENT
Prepare an alignment screen. A properly aligned fog lamp will project a pattern on the alignment screen 100 mm (4 in.) below the fog lamp centerline and straight ahead (Fig. 3).
Rotate the adjustment screw (Fig. 4) to obtain the correct pattern.

GENERAL INFORMATION
DAYTIME RUNNING LAMP SYSTEM
ZJ vehicles built for use in Canada are equipped with a Daytime Running Lamp System (DRL). The DRL system operates the headlamp at 50% illumination with the headlamp switch OFF, park brake released and the ignition in the RUN position. The DRL system is controlled by the Daytime Running Lamp Module located in the engine compartment attached to the Power Distribution Center (PDC) bracket. The DRL module overides the headlamp switch when the headlamps are turned OFF. The headlamps operate normally when the headlamps are turned ON.
LAMP OUTAGE MODULE
The Lamp Outage Module will indicate a tail lamp, stop lamp, or a CHMSL bulb failure. A display will illuminate in the Vehicle Information Center (VIC), displaying the failure.
Details for the VIC can be found in Group 8E, Vehicle Information Center. For circuit information, refer to Group 8W, Wiring Diagrams.
The Lamp Outage Module is located behind the left quarter trim panel.
Connecting trailer lights to the body harness at the rear of the vehicle can cause damage to the lamp outage module. The lamp outage module is designed to handle a 5 amp current load. This is adequate for the operation of the vehicles lighting system. When additional lights are added to the system such as trailer lights, the 5 amp limit can be exceeded. This can cause failure of the lamp outage module.
If trailer towing is required and the vehicle is not equipped with a trailer tow package, the MOPAR accessory trailer towing harnesses are the only approved method to provide additional trailer lights. These harnesses are designed to provide current to the trailer lights but bypass the lamp outage module.
