DESCRIPTION AND OPERATION
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.
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. Turn
signal lamp circuitry always comes from the multi-
function switch, and goes to the cluster connector,
into the cluster, then back out to the front turn sig-
nal switch lamps. The Canadian cluster provides
steady illumination of the front turn signal when the
ignition switch is in the ON position. The DRL func-
tion may be inhibited by activating the turn signals,
the hazard flashers, the headlamp switch, or park
brake.
DIAGNOSIS AND TESTING
HEADLAMP DIAGNOSIS
Always begin any diagnosis by testing all of the
fuses and circuit breakers in the system. Refer to
Group 8W, Wiring Diagrams.
Conventional and halogen headlamps are inter-
changeable. It is recommended that they not be
intermixed on a given vehicle.

SECTION IDENTIFICATION
The wiring diagrams are grouped into individual
sections. If a component is most likely found in a par-
ticular group, it will be shown complete (all wires,
connectors, and pins) within that group. For exam-
ple, the Auto Shutdown Relay is most likely to be
found in Group 30, so it is shown there complete. It
can, however, be shown partially in another group if
it contains some associated wiring.
SYMBOLS
International symbols are used throughout the wir-
ing diagrams. These symbols are consistent with
those being used around the world.
