GENERAL INFORMATION
INTRODUCTION
WARNING: ON VEHICLES EQUIPPED WITH AIR-
BAG, SEE GROUP 8M, RESTRAINT SYSTEMS FOR
AIRBAG REMOVAL PROCEDURES.
The turn signals are part of the multi-function
switch. Which contains:
²Electrical circuitry for turn signals
²Hazard warning switch
²Headlamp beam select switch
²Headlamp optical horn
The integrated switch assembly is mounted to the
left hand side of the steering column. When the
driver wishes to signal his intentions to change direc-
tion of travel, he moves the lever upward to cause
the right signals to flash and downward to cause the
left signals to flash. After completion of a turn the
system is deactivated automatically. As the steering
wheel returns to the straight ahead position, a can-
celing cam molded to the clockspring mechanism
comes in contact with the cancel actuator on the turn
signal multi-function switch assembly. The cam lobe,
pushing on the cancel actuator, returns the switch to
the off position.
If only momentary signaling such as indication of a
lane change is desired, the switch is actuated to a
left or right intermediate detent position. In this
position the signal lamps flash as described above,
but the switch returns to the OFF position as soon as
the lever is released.
When the system is activated, one of two indicator
lamps mounted in the instrument cluster flashes in
unison with the turn signal lamps, indicating to the
driver that the system is operating.
DESCRIPTION AND OPERATION
HAZARD WARNING SYSTEM
The hazard warning system is actuated by a slide
button located on the top of the steering column
between the steering wheel and the instrument
panel. The hazard switch is identified with a double
triangle on front of the button.
COMBINATION FLASHER
The turn signal flasher and the hazard warning
flasher are combined into one unit called a combina-
tion flasher (combo-flasher). The combo- flasher con-
trols the flashing of the hazard warning system and
the turn signal system. An inoperative bulb or incom-
plete turn signal circuit will cause the flasher rate to
double.
The combo-flasher is located on the fuse block. The
combo-flasher is black in color for ease of identifica-
tion (Fig. 1).

DIAGNOSIS AND TESTING
MULTI-FUNCTION SWITCH
The multi-function switch contains electrical cir-
cuitry for turn signal, hazard warning, headlamp
beam select, headlamp optical horn. This integratedswitch assembly is mounted to the left hand side of
the steering column. Should any function of the
switch fail, the entire switch assembly must be
replaced. Refer to Multi-function Switch Test Table
for diagnosis.

GENERAL INFORMATION
GENERAL 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 and coat the inside of the socket lightly with
Mopar Multi-Purpose Grease or equivalent.
SAFETY PRECAUTIONS
WARNING: EYE PROTECTION SHOULD BE USED
WHEN SERVICING GLASS COMPONENTS. PER-
SONAL INJURY CAN RESULT.
CAUTION: Do not touch the glass of halogen bulbs
with fingers or other possibly oily surface, reduced
bulb life will result.
Do not use bulbs with higher candle power than
indicated in the Bulb Application table at the end of
this group. Damage to lamp and/or Daytime Run-
ning Lamp Module can result.
Do not use fuses, circuit breakers or relays hav-
ing greater amperage value than indicated on the
fuse panel or in the Owners Manual.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.
DAYTIME RUNNING LAMP MODULE
PL vehicles built for use in Canada are equipped
with a Daytime Running Lamp (DRL) system. The
DRL system operates the headlamps at 50% illumi-
nation with the headlamp switch OFF, park brake
released and the ignition ON. The DRL system is
controlled by the Daytime Running Lamp Module.
The DRL module overrides the headlamp switch
when the headlamps are turned OFF. The headlamps
operate normally when the headlamps are turned
ON.
DIAGNOSIS AND TESTING
DIAGNOSTIC PROCEDURES
When a vehicle experiences problems with the
headlamp system, verify the condition of the battery
connections, charging system, headlamp bulbs, wire
connectors, relay, high beam dimmer switch and
headlamp switch. Refer to Group 8W, Wiring Dia-
grams for component locations and circuit informa-
tion.
PLLAMPS 8L - 1

HEADLAMP DIAGNOSIS

GENERAL INFORMATION
HEADLAMP ALIGNMENT
Headlamps can be aligned using the screen method
provided in this section.
SERVICE PROCEDURES
HEADLAMP 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 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.
ADJUSTMENTS
HEADLAMP ADJUSTMENT USING ALIGNMENT
SCREEN
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. 1).
(2) If necessary, tape a line on the floor 7.62
meters (25 ft.) away from and parallel to the wall.
(3) From the floor up 1.27 meters (5 ft.), tape a
line on the wall at the center line of the vehicle.
Sight along the center line of the vehicle (from rear
of vehicle forward) to verify accuracy of the line
placement.
(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 head-
lamp 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 center line of the
vehicle to the center of each headlamp being aligned.
Transfer measurements to screen (with tape) to each
side of vehicle center line. Use these lines for left/
right adjustment reference.
HEADLAMP ADJUSTMENT
A properly aimed low beam headlamp will project
the center of the low beam hot spot on the alignment
screen from 178 mm (7 in.) below the headlamp cen-
ter line. The side- to-side left edge of low beam hot
spot should be 127 mm (5 in.) to the right of head-
lamp center line (Fig. 1). The high beams on a vehi-
cle 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 to achieve the specified low beam hot spot
pattern.
FOG LAMP ALIGNMENT
Prepare an alignment screen. Refer to Alignment
Screen Preparation paragraph in this section. Disen-
gage the wire connectors from the back of the head-
lamp bulbs to disable the headlamps. This will allow
a more accurate projection reading of the fog lamps.
Turn on the headlamp switch and actuate the fog
lamp switch. 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. 2).
