DESCRIPTION AND OPERATION
(Left–Hand Drive Shown, Right–Hand Drive Similar)
AIRBAG MODULE
Driver Airbag Module
Caution: Tampering with the driver side airbag
module creates the risk of an injury from an unex-
pected deployment. Therefore, the driver side air-
bag module should never be disassembled.
The driver airbag module is under the center pad on the
steering wheel.
The driver airbag module contains an ignitor charge and
a gas generator to inflate the folded airbag.
D110B006
Passenger Airbag Module
Caution: Tampering with the passenger side airbag
module creates the risk of an injury from an unex-
pected deployment. Therefore, the passenger side
airbag module should never be disassembled.
The passenger airbag module is on the passenger side
of the instrument panel.
The passenger airbag module contains an ignitor charge
and a gas generator to inflate the folded airbag.
SENSING AND DIAGNOSTIC
MODULE (SDM)
The SDM

Has no user-serviceable parts.

Is under the front console assembly.

Continuously monitors the system components.

Records any faults which are discovered.
Illuminates a warning lamp that alerts the driver to
any faults.

Allows the fault codes to be retrieved with a scan tool.
The SDM controls the deployment of the airbag system
through the use of the

Arming sensor.

Capacitor.

Crash sensor, or accelerometer.
D110B007
Arming Sensor
The arming sensor is safety device made up of a dual-
contact, electro-mechanical switch that:

Acts independently of the electronic components.

Keeps the firing circuits for the airbags unarmed un-
der normal driving conditions.

Allows the airbags to deploy under the required
conditions.
Capacitor
The capacitor provides reserve power.
Crash Sensor
The crash sensor, or accelerometer, electronically rep-
resents the acceleration or deceleration of the vehicle
during a frontal impact. In this electronic representation,
the electrical signal is proportional to the acceleration or
deceleration of the vehicle.
SIR WARNING LAMP
The supplemental inflatable restraints (SIR) system in-
cludes a self-diagnostic function.

D110B001
GENERAL PRECAUTIONS
The supplemental inflatable restraints (SIR) warning
lamp must illuminate when the ignition is switched ON,
and then turn OFF after approximately 4 seconds.
There is a fault in the airbag system if

The warning lamp does not turn OFF.

The warning lamp illuminates while the vehicle is in
operation.If the warning lamp indicates there is a fault in the airbag
system, assume that the SIR system may not be
functional.
Caution: Failure to follow all service procedures in
the correct sequence can cause the airbag system to
deploy unexpectedly and possibly cause a serious
injury.
Only trained personnel at franchised Daewoo dealers
and authorized Daewoo service dealerships may service
the airbag system.
Never attempt to disassemble, repair, or reuse the

Airbag modules.

Clock spring.

Sensing and diagnostic module.

Wiring harness.
When making SIR repairs,

Inspect any SIR part before it is installed.

Use only new parts.

Do not install used SIR parts from other vehicles.

Do not install any part that has been dropped or that
has dents, cracks, or other defects.
AIRBAG DEPLOYMENT CONDITION
Airbag is designed to deploy under 30 left/right angle
barrier and above 25 km/h (15 mph) speed.
Concrete Barrier Deployment Condition
In case of the 0 frontal concrete battier, airbag may
deploy above 25 km/h (15 mph) speed.

DIAGNOSTIC INFORMATION AND PROCEDURES
D110B009A
BULB CHECK
As soon as the operating voltage is applied to the sens-
ing and diagnostic module (SDM) ignition input, the
SDM activates the warning lamp for a bulb check.
The SDM turns the lamp ON for 4 seconds, and then the
SDM turns the lamp OFF.
During the bulb check, the SDM is not ready to detect a
crash or deploy the supplemental inflatable restraints.
FAULT INDICATION
The sensing and diagnostic module records the sys-
tem’s faults in two categories:

Current faults and the fault code appears “Axx” on the
scan tool display.

Historic faults, which are those that were detected in
the past, but are no longer active. And the fault code
appears “Sxx” on the scan tool display.
The warning lamp:

Indicates a fault as soon as it occurs.

Stays ON, even if a fault is no longer active.A scan tool connected to the data link connector (DLC):

Reveals the fault codes.

Receives serial data transmission through the termi-
nal J (13) of the DLC.

Receives ground through the terminal A (4) of the
DLC.
CLEARING FAULT CODES
When the sensing and diagnostic module (SDM) re-
ceives the CODE ERASE command from the scan tool,
the SDM:

Clears the entire fault memory.

Turns OFF the warning lamp.

Resets for fault detection.
External Fault
Service personnel can reset the SDM and turn OFF the
warning lamp if the fault is an external fault.
Internal Fault
An internal fault of the SDM or a CRASH RECORDED
fault code cannot be reset.
In the case of an internal fault of the SDM or a CRASH
RECORDED fault code, the SDM must be replaced.
Voltage-Low Fault
The SDM will turn OFF the VOLTAGE LOW fault as
soon as the voltage recovers.
MICROPROCESSOR –
INDEPENDENT LAMP ACTIVATION
If the sensing and diagnostic module (SDM) electrical
connector is not properly attached, the SDM cannot
function and cannot control the warning lamp.
If this fault is present, the warning lamp will operate in-
dependently from the SDM through the use of shorting
bars that are built into the SDM connector.

AIRBAG MODULE DEPLOYMENT
(IN VEHICLE)
(Left–Hand Drive Shown, Right–Hand
Drive Similar)
Deploy the airbags before disposing of them. This in-
cludes those in a whole vehicle being scrapped.
If the vehicle is still within the warranty period, contact
the Daewoo regional service manager for approval or
special instructions before deploying the airbag mod-
ules.
Caution: Before deploying the airbags, remove all
loose objects from the airbags expansion area.
Caution: Deploy the airbags with the vehicle doors
closed and the side windows open.
Caution: Deploy the airbags only in an evacuated
area. Service personnel who must be present dur-
ing the deployment should be at least 10 meters
(33 feet) in front of the vehicle.
Caution: Do not connect the voltage source until af-
ter having completed all other preparations for the
deployment of the airbags.
Caution: Allow a deployed airbag module to cool
for at least 30 minutes before handling.
Caution: Wear the gloves and the eye protectors
during the disposal process.
Caution: If the deployment fails, disconnect the volt-
age source and wait 5 minutes before approaching
the vehicle.
Deployment Procedure
1. Disconnect both battery cables and place the battery
at least 10 meters (32.8 feet) from the vehicle.
Caution: Wait 1 minute after disconnecting both
battery cables to allow the capacitor inside the
sensing and diagnostic module (SDM) to discharge
before taking any other action. The capacitor sup-
plies the reserve power to deploy the airbags, even
if the battery is disconnected. Unintentional deploy-
ment of the airbags can cause injury.
2. Remove the lower cover from the steering column.
3. At the lower steering column, cut the two wires lead-
ing from the supplemental inflatable restraint (SIR)
harness to the clock spring.
4. Strip 13 mm (0.5 inch) of insulation from the ends of
the wires leading to the clock spring.
5. Use two additional wires, each at least 10 meters
(33 feet) long, to reach from the deployment battery
to the airbag module.
6. Strip 13 mm (0.5 inch) of insulation from the ends of
these two additional wires.
7. Twist the two wires together at one end.

AIRBAG MODULE DEPLOYMENT
(OUTSIDE OF VEHICLE)
Deploy all intact airbag modules that have been

Removed from a scrapped vehicle.

Found to be defective.

Found to have been damaged during transit, storage,
or service.
Caution: Deploy the airbags only in an evacuated
area. Service personnel who must be present dur-
ing the deployment should be at least 10 meters
(33 feet) in front of the vehicle.
Caution: Do not connect the voltage source until
completing all other preparations for the deploy-
ment of the airbags.
Caution: Allow a deployed airbag module to cool
for at least 30 minutes before removing it from the
vehicle.
Caution: Wear gloves and eye protection during the
disposal process.
Caution: If the deployment fails, disconnect the volt-
age source and wait 5 minutes before approaching
the vehicle.
1. Position the airbag module face up, on flat ground
outdoors, at least 10 meters (33 feet) from any ob-
stacles or people.
2. Place a vehicle battery at least 10 meters (33 feet)
away from the airbag module.
3. Deploy the airbag module using the deployment tool.
4. Using the proper precautions, dispose of the
deployed airbag. Refer to “Deployed Airbag Module
Disposal Procedure” in this section.
DEPLOYED AIRBAG MODULE
DISPOSAL PROCEDURE
Caution: After an airbag module has been
deployed, the surface of the airbag may contain a
powdery residue. The powder lubricates the airbag
as it inflates. The dust that is produced as a by-
product of the deployment is unlikely to be harmful,
but use the gloves and the safety glasses in order to
prevent any possible irritation of the skin and the
eyes.
Caution: After deployment, the metal surfaces of
the airbag module will be hot. In order to avoid the
risk of an injury or a fire, do not place the deployed
airbag modules near any flammable objects, and al-
low the airbag modules to cool for 30 minutes be-
fore handling them.
Deploy an airbag before disposing of it. This includes
those in a whole vehicle being scrapped.

special instructions before deploying an airbag module.
Deployed airbag modules should be disposed of in the
same manner as any other scrap parts, with the addition
of the following steps:
1. Place the deployed airbag in a sturdy plastic bag.
2. Seal the plastic bag securely.
3. Wash your hands and rinse them with water after
handling a deployed airbag.

9B – 2 LIGHTING SYSTEMS
DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
HEADLAMPS AND PARKING LAMPS
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
parking lamps, the license plate lamps and the instru-
ment panel illumination. Turning the switch to the sec-
ond position turns on all of the previous lamps and the
headlamps. Turning the switch to the off position turns
off all the lamps.
The parking lamps can be turned on by turning the light-
ing switch to the first position. The parking lamps can be
turned off by turning the switch to the OFF position.
Headlamp high beam and low beam are also controlled
by this lever. When the headlamps are on, pushing the
lever away from the driver until the switch clicks
changes the lamp from low beam to high beam. An indi-
cator 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 service repairs to
the front end area may have disturbed the headlamp as-
sembly or its mountings.
FRONT TURN SIGNAL LAMPS
When the turn signals are activated, the side turn signal
lamps flash to signal a turn. The turn signal works only
when the ignition switch 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 turn sig-
nals. When the turn is completed, the lever will return to
horizontal and the turn signals will stop flashing.
For changing lanes or shallow turns where the steering
wheel does not turn far enough to cancel the signal,
move the signal only to the first detent and hold it there.
When the lever is released, it will return to horizontal and
the turn signal will cancel.
REAR FOG LAMP
The rear fog lamp is incorporated in the drive side tail-
lamp assembly and are controlled by the rear fog lamp
switch on the instrument panel. The rear fog lamp can
be turned on only when headlamps are on.
TAILLAMPS
The taillamps, stoplamps, backup lamp(s), rear fog lamp
(if equipped with) and turn signal lamps are one assem-
bly.
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 LAMPS
The license plate lamps will come on when the head-
lamps or the parking lamps are on. The license plate
lamps are mounted on the rear bumper, above the li-
cense plate.
INTERIOR COURTESY LAMP
The courtesy lamp is located on the headliner just be-
fore the front seats. The lamp switch has three posi-
tions. If the switch is 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.
BACKUP LAMP(S)
The backup lamps are located in the rear combination
lamps. They will come on when the transaxle is shifted
into REVERSE. On a vehicle with a manual transaxle,
they are activated by a reverse switch which is part of
the transaxle.
DAYTIME RUNNING LAMPS (DRL)
(W/Europe Only)
The daytime running lamps (DRL) work in conjunction
with the exterior lamps system. When the ignition switch
is turned to the ”II” position with the light switch off, park-
ing, tail, license plate and instrument panel lights illumi-
nate. And, when the engine is started, the headlamps
(low beam) also come on.
They remain on until the ignition switch is turned off or
the light switch is turned on. They revert to normal op-
eration when the light switch is on.
The daytime running lamps (DRL) is optional.
