GENERAL INFORMATION
INTRODUCTION
The turn signals are actuated with a lever on the
left side of the steering column just ahead 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.
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:
²Combination flasher
²Multi-function switch
²Turn indicator lamp
²Front and rear turn signal bulbs.
A chime will sound after the vehicle has traveled a
distance of approximately 0.5 mile with the turn sig-
nal ON.
COMBINATION FLASHER
The Turn Signal/Hazard Warning Flasher is a
module providing the vehicle with turn signal and
hazard warning functions and has been designed
with internal relays to take advantage of low current
switching requirements in the vehicle. It is plugged
into the Junction Block at position 4 (Fig. 1), where
all wiring associated with its operation is terminated.The Junction Block is adjacent to and left of the
steering column of the vehicle.
To gain access to the flasher, remove the lower
steering column cover and knee blocker. Refer to
Group 8E, Instrument Panel and Systems for
removal procedures.

GENERAL INFORMATION
GENERAL INFORMATION
NS vehicles use lighting on the interior and exte-
rior of the vehicle for illuminating and indicating
purposes. Lighting circuits are protected by fuses.
Lighting circuits require an overload protected power
source, on/off device, lamps and body ground to oper-
ate properly. Plastic lamps require a wire in the har-
ness to supply body ground to the lamp socket.
Replace sockets and bulbs that are corroded.
Some of the interior and exterior lighting functions
are governed by the body controller. The headlamp,
dome, and the door ajar switches provide signals to
the body controller. The body controller in turn acti-
vates relay(s) in order to provide either a ground or
feed line to the appropriate lamp(s).
Wire connectors can make intermittent contact or
become corroded. Before coupling wire connectors,
inspect the terminals inside the connector. Male ter-
minals should not be bent or disengaged from the
insulator. Female terminals should not be sprung
open or disengaged from the insulator. Bent and
sprung terminals can be repaired using needle nose
pliers and pick tool. Corroded terminals appear
chalky or green. Corroded terminals should be
replaced to avoid recurrence of the problem symp-
toms.
Begin electrical system failure diagnosis by testing
related fuses in the fuse block and power distribution
center. Verify that bulbs are in good condition andtest continuity of the circuit ground. Refer to Group
8W, Wiring Diagrams, for component location and cir-
cuit 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.
ELECTRONIC DAYTIME RUNNING LIGHT (DRL)
The Combination Flasher/DRL is a module provid-
ing turn signal, hazard warning, and daytime run-
NSLAMPS 8L - 1
ning light functions (for Canadian vehicles), and has
been designed with internal relays to take advantage
of low current switching requirements in the vehicle.
It is plugged into the junction block at positions
three and four (Fig. 1), where all wiring associated
with its operation is terminated. The junction block
is adjacent to and left of the steering column of the
vehicle. For diagnostic information refer to Group 8J,
Turn Signal and Flashers.
On vehicles built for use in the United States, only
position four is used. Vehicles built for use in Canada
utilize both positions three and four.
To gain access to the device, remove the lower
steering column cover and knee blocker. Refer to
Group 8E, Instrument Panel and Gauges.SYSTEM FUNCTION
The combination-flasher/DRL may be operated in
its hazard warning mode either with or without the
ignition circuit being active. However, in order to
operate in the turn signal mode or the DRL mode,
the ignition circuit must be completed to the module.
While the combination-flasher portion is idle, there
is no current drawn through the module. The device
does not become active in the turn signal or hazard
warning modes until a signal ground circuit is sup-
plied to either of the turn signal inputs or the hazard
warning input. With the ignition OFF, there is no
current drawn through the module.
While the ignition is ON, the front turn signal fil-
aments are illuminated steadily thus providing the
DRL function. The DRL function may be inhibited by
applying a signal ground input from either the park
brake circuit or the headlamp relay activation circuit.
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.
