OXYGEN SENSOR (O2S1)
Removal Procedure
1. Remove the air cleaner/resonator assembly. Refer to
Section 1B, SOHC Engine Mechanical.
2. Remove the oxygen sensor.
Disconnect the oxygen sensor connector (1).
Remove the oxygen sensor (2).
Notice: The oxygen sensor uses a permanently at-
tached pigtail and connector. This pigtail should not be
removed from the oxygen sensor. Damage or removal
of the pigtail or the connector could affect proper opera-
tion of the oxygen sensor. Take care when handling the
oxygen sensor. Do not drop the oxygen sensor.
D12F547A
Installation Procedure
1. Install in the reverse order of removal.
Important: A special anti–seize compound is used on
the oxygen sensor threads. This compound consists of
a liquid graphite and glass beads. The graphite will burn
away, but the glass beads will remain, making the sen-
sor easier to remove. New or service sensors will al-
ready have the compound applied to the threads. If a
sensor is removed from any engine and if for any reason
it is to be reinstalled, the threads must have anti–seize
compound applied before reinstallation.
2. Install the oxygen sensor.
Tighten
Tighten the oxygen sensor to 35~44 Nm (26~33 lb-
ft).
MAA1F470
HEATED OXYGEN SENSOR (HO2S2)
Removal and Installation Procedure
1. Disconnect the negative battery cable.
2. Remove the front center console.
3. Disconnect the HO2S2 connector.
4. Remove the front exhaust pipe. Refer to Section 1G,
Engine Exhaust.
5. Remove the HO2S2 from the front exhaust pipe.
Installation Procedure
1. Install in the reverse order of removal.

SUPPLEMENTAL INFLATABLE RESTRAINTS (SIR) 8B–3
DAEWOO M-150 BL2
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.

9G –2 INTERIOR TRIM
DAEWOO M-150 BL2
DESCRIPTION AND OPERATION
INTERIOR TRIM PANELS
The interior trim panels are molded plastic and fasten
with screws or plastic clips.
PRESSURE RELIEF VENT
When all the windows are closed and the ventilation sys-
tem is on, the addition of outside air to the interior of the
vehicle causes a positive pressure within the vehicle. In
order to relieve the pressure, air is released through one
pressure relief vents. The pressure relief vent is located
in the luggage compartment, behind the spare wheel.
FLOOR CONSOLE
The floor console fits over the tunnel in the floor of the
vehicle and extends from under the center of the instru-
ment panel to the front seat area. The floor console con-
tains the transaxle shift lever and a cupholder.
The sensing and diagnosis module (SDM) for the airbag
system is located under the floor console.
PARKING BRAKE CABLE COVER
The parking brake cable cover should be removed to ad-
just the free play of the parking brake cable.
FLOOR CARPET
The molded one-piece floor carpet goes over both the
front and the rear floor pans.

FRAME AND UNDERBODY 9N–3
DAEWOO M-150 BL2
REPAIR INSTRUCTIONS
ON–VEHICLE SERVICE
ALIGNMENT CHECKING
An accurate method of determining the alignment of the
underbody uses a measuring tram gauge. The tram
gauge set used to perform the recommended measuring
checks must include a vertical pointer able to reach
457 mm (18 inches).
Two types of measurements can be made with a tram
gauge: direct point-to-point measurements and mea-
surements calculated on a horizontal plane (datum line)
parallel to the underbody. Point-to-point measurements
are generally taken on steering and suspension engine
compartment parts and simply require the vertical point-
ers to be set equally.
For horizontal plane measurements, the vertical pointers
must be set as specified for each point to be measured.
Dimensions-to-gauge holes are measured to the center
of the holes and flush to the adjacent surface metal un-
less otherwise specified. It is recommended that the di-
agonal dimensions to the cross-body be checked on
both sides in order to verify the dimensional accuracy of
the vehicle underbody.
FLOOR PAN INSULATORS
The floor pan insulators have been designed for the
higher floor pan temperatures that result from the use
of the catalytic converter in the exhaust system. There-
fore, when servicing a vehicle, it is essential that any in-sulators that may have been disturbed or removed be
reinstalled in the original sequence and location. Also, if
an insulator needs to be replaced, use only the insula-
tion specified for that location on the floor pan.
When servicing or replacing interior insulators, observe
the following instructions.

Install the insulators in the original position and se-
quence. Butt the pieces together in order to avoid
gapping or overlapping.

If it is necessary to replace an insulator, use only the
specified insulation.

Use the original part to determine the amount of re-
placement material required and as a template for
cutting and fitting the new piece to the floor pan.

When installing the insulator, do not enlarge any cut-
outs or holes that are used for the attachment of interi-
or parts such as the instrument panel or the floor
console.

Route the cross-body harness for interior parts over
the floor pan insulators. Clip it in the original location.

Do not apply spray-on deadeners or trim adhesives to
the top of the floor pan at the area directly over the
catalytic converter or the muffler.
Any insulator service repair or replacement should be
the same thickness, size, and location as the original
installation in the vehicle.
