8B – 102ISUPPLEMENTAL INFLATABLE RESTRAINTS (SIR)
DAEWOO V–121 BL4
spring should never be disassembled, and there is no
timekeeping function. The clock spring contains two or
three current–carrying coils. One of the current–carrying
coils maintains continuous contact within the driver de-
ployment loop while the steering wheel is rotated. The
clock spring also contains coils that maintain continuous
contact for horn and remote audio control switch circuit.
Turning the steering wheel in one direction tightens the
coil, and turning the steering wheel in the opposite direc-
tion loosens the coil. Do not turn the clock spring when the
steering wheel is not attached. Refer to ”Clock Spring” in
this section for proper installation of the clock spring.
The clock spring also includes the wiring and the connec-
tors for the horn circuit and the driver airbag circuit. A yel-
low two–way connector on the lower steering column is at-
tached to the clock spring wiring. The yellow connector to
the airbag contains a shorting bar which connects the driv-
er high circuit to driver low circuit when the connector is
disconnected.
The shorting bar prevents current from travelling through
the driver airbag module during servicing. The shorting bar
is disengaged when the clock spring connector is con-
nected.WIRING HARNESS CONNECTORS
If the sensing and diagnostic module (SDM) electrical con-
nector is not attached properly, a built in shorting bar will
connect the wire from airbag warning lamp with the SDM
ground wire. This turns on the airbag indicator . To prevent
deployment during servicing, additional shorting bars are
located in following locations :
S The clock spring electrical connector at the lower
steering column.
S The passenger airbag module.
S The driver airbag module.
S The seat belt pretensioners.
The shorting bar is only a backup safety device. Always
disable the supplemental inflatable restraints(SIR) before
beginning any service procedure.

Diagnostic Aids :
The fuse for the left–side taillamps is also part of the headlamps–on reminder chime circuit. The headlamps–on reminder
chime should operate when the ignition is OFF, the headlamps or parking lamps are on, and the driver door is open.

GENERAL DESCRIPTION
AND SYSTEM OPERATION
HEADLAMPS–ON REMINDER CHIME
When the headlamp switch is in the headlamps–on or
parking lamps–on position, voltage is applied to the chime
module. When the ignition is in ON, ACC or START, volt-
age is applied through the fuse block to the module. These
two voltages are sensed, and the chime module is not
sounded.
When the ignition is not in ON, ACC or START, the module
loses voltage. The chime module senses change. If the
voltage is still available, it is applied to sound the chime.
The chime can be turned off by turning the headlamp
switch off. The module no longer senses voltage from the
headlamp switch, so the chime module does not sound.
HEADLAMPS
The headlamps are controlled by the multifunction lever
located on the left side of the steering column. They will
come on with the ignition switch in any position. Turning
the headlamp switch to the first position turns on the park-
ing lamps, the license plate lamps and the instrument pan-
el illumination. Turning the switch to the second position
turns on all of the previous lamps and the headlamps.
Turning the switch to the OFF position turns off all the
lamps.
Headlamp high beams and low beams are also controlled
by this lever. When the headlamps are on, pushing the le-
ver away from the driver until the switch clicks changes the
lamp from low beam to high beam. An indicator lamp on
the instrument cluster assembly will come on when the
high beam headlamps are on. To return the headlamps to
low beam, pull the lever toward the driver.
The headlamps must be aimed for proper illumination of
the road. Headlamp aim should be checked whenever a
new headlamp assembly is installed, or whenever service
repairs to the front end area may have disturbed the head-
lamp assembly or its mountings.
DAYTIME RUNNING LAMPS
The Daytime Running Lamps (DRL) will come on when:
S The ignition is ON.
S The light is OFF.
S The parking brake is released.
When the exterior lights are on, the DRL will turn off. To
turn the DRL off when idling, apply the parking brake.
PARKING AND TURN SIGNAL LAMPS
The parking lamps can be turned on by turning the lighting
switch to the first position. The parking lamps can be
turned off by turning the switch to the OFF position.When the turn signals are activated, the front and rear turn
signal lamps flash to signal a turn. The turn signals work
only when the ignition is ON.
The turn signals are controlled by the light switch on the
left side of the steering column. Moving the lever all the
way up or down (past the detent) will turn on the front and
rear turn signals. When the turn is completed, the lever will
return to horizontal and the turn signals will stop flashing.
For changing lanes, or for shallow turns in which the steer-
ing wheel does not turn far enough to cancel the signal,
move the signal lever only to the first detent and hold it
there. When the lever is released, it will return to horizontal
and the turn signals will cancel.
FOG LAMPS
The fog lamp switch is on the instrument panel to the right
of the steering column. To use the fog lamps, first turn on
the headlamps or the parking lamps. Then push the fog
lamp switch. The indicator light in the switch will illuminate
to indicate that the fog lamps are on. Push the switch again
to turn off the fog lamps. The indicator light will then go off.
The fog lamps should not be used as a substitute for the
headlamps.
The fog lamps must be aimed for proper illumination of the
road. Fog lamp aim should be checked when a new bulb
is installed or if service or repairs in the front end area may
have disturbed the fog lamp mountings.
REAR COMBINATION LAMPS
The taillamps, stoplamps, turn signal lamps and backup
lamp are one assembly.
Turning on either the headlamps or the parking lamps will
also turn on the taillamps. When the brake pedal is
pushed, the taillamps will glow brighter to serve as sto-
plamps.
The center high–mounted stoplamp is located in the rear
window and will come on when the brake pedal is pressed.
LICENSE PLATE LAMP
The license plate lamps will come on when the headlamps
or the parking lamps are on. The license plate lamps are
mounted above the license plate.
INTERIOR COURTESY LAMP
The courtesy lamp is located on the headliner just behind
the front seats. The lamp switch has three positions. If the
switch is left in the center position, the lamp will go on
whenever a door is opened and go off when it is closed.
In the ON position, the lamp will stay on until it is turned off.
In the OFF position, the lamp will not come on, even when
a door is opened.
LUGGAGE COMPARTMENT LAMP
The luggage compartment lamp is located under the deck
lid sill plate on the notchback. The lamp is located on the
left–side wheelhouse trim panel on the hatchback. It will
come on whenever the luggage compartment is opened.
