DIAGNOSTIC TROUBLE CODE (DTC) P0135
FRONT HEATED OXYGEN SENSOR (HO2S1) HEATER
CIRCUIT NOT FUNCTIONING
Circuit Description
Heated oxygen sensors (HO2S) are used for fuel control
and post catalyst monitoring. Each HO2S compares the
oxygen content of the surrounding air with the oxygen con-
tent in the exhaust stream. The HO2S must reach operat-
ing temperature to provide an accurate voltage signal. A
heating element inside the HO2S minmizes the time re-
quired for the sensor to reach operating temperature. Volt-
age is provided to the heater by the ignition 1 voltage cir-
cuit through a fuse. With the engine running, ground is
provided to the heater by the HO2S heater low control cir-
cuit, through a low side driver within the engine control
module (ECM). The ECM monitors the current flow
through the heater for diagnosis.
If the ECM detects that the HO2S heater current is above
or blelow a specified range, DTC P0135 seats.
Conditions for Setting the DTC
S DTCs P0106, P0117, P0118, P1017 are not set.
S Engine run time is greater than 200 seconds.
S Filtered O2 heater current is less than 0.025 amps.
Action Taken When the DTC SetsS The Malfunction Indicator Lamp (MIL) will illuminate
after three consecutive ignition cycle with a fail.
S The ECM will record operating conditions at the
time the diagnostic fails. This information will be
stored in the Freeze Frame and Failure Records
buffers.
S A history Diagnostic Trouble Code (DTC) is stored.
Conditions for Clearing the MIL/DTC
S The MIL will turn off after three consecutive ignition
cycles in which the diagnostic runs without a fault.
S A history DTC will clear after 40 consecutive warm–
up cycles without a fault.
S DTC(s) can be cleared by using the scan tool.
Diagnostic Aids
An intermittent may be caused by rubbed through wire in-
sulation or a wire contacting the exhaust.
Check for poor connection or damaged harness – inspect
harness connectors for the following conditions:
S Improper mating
S Broken locks
S Improperly formed
S Damaged terminals
S Poor terminal–to–wire connection

2E – 8ITIRES AND WHEELS
DAEWOO V–121 BL4
TIRE AND WHEEL
MATCH–MOUNTING
The tires and wheels are match–mounted at the assembly
plant. Match–mounting aligns the radially stiffest part of
the tire, or high spot, to the smallest radius, or low spot, of
the wheel.
The high spot of the tire is originally marked by a red paint
mark or an adhesive label on the outboard sidewall.
The low spot of the wheel will be at the location of the valve
stem.
Before dismounting a tire from its wheel, scribe a line on
the tire at the valve stem to assure that it is remounted in
the same position.
Replacement tires that are of original equipment quality
will have their high and low spot marked in the same man-
ner.
TIRE MOUNTING AND DISMOUNTING
Notice : Use a tire–changing machine to mount or dis-
mount the tires. Follow the equipment manufacturer’s in-
structions. Do not use hand tools or tire irons to change
tires. These tools may damage the beads or the wheel rim.
1. Clean the rim bead seats with a wire brush or
coarse steel wool to remove lubricants, old rubber,
and light rust. Before mounting or dismounting a
tire, lubricate the bead area well with an approved
tire lubricant.
CAUTION : To avoid serious injury, do not stand over
the tire when inflating it, because the bead may break
when it snaps over the safety hump. Do not exceed
275 kPa (40 psi) of air pressure in any tire if the beads
are not seated. If 275 kPa (40 psi) of air pressure will
not seat the beads, deflate the tire. Relubricate the
bead and reinflate the tire. Overinflation may cause
the bead to break and cause serious injury.
2. fter mounting the tire, inflate it until the beads are
seated. Never exceed 275 kPa (40 psi) to seat the
beads.
3. Install the valve core and inflate the tire to the prop-
er pressure. Make sure the locating ring outside of
the bead of the tire shows around the rim flanges of
the wheel on both sides. This positioning of the tire
will insure that the bead of the tire is seated.

MANUAL CONTROL HEATING, VENTILATION AND AIR CONDITIONING SYSTEM 7B – 19
DAEWOO V–121 BL4
MAINTENANCE AND REPAIR
ON–VEHICLE SERVICE
GENERAL A/C SYSTEM SERVICE PROCEDURES
O–RING REPLACEMENT
Important : Even though O–rings may look identical, it is
extremely important that only recommended service re-
placement air conditioning O–rings be used or excessive
leakage of refrigerant may occur.
Important : Always slip the O–ring onto the flange tube to
ensure proper locating and sealing.
Install new Daewoo–approved service replacement air
conditioning (A/C) O–rings whenever a joint or a fitting is
disassembled, except when the O–rings are provided on
new components.
When replacing O–rings on an A/C component or a joint
connection, the fitting design should be identified to en-
sure installation of the correct air conditioning service re-
placement O–ring. Some joint connections and compo-
nents will implement a ”captured” O–ring design fitting that
uses a groove to retain the O–ring. Others do not have a
groove and use a ”non–captured” or ”standard” O–ring.
Assembly and tightening procedures are the same for
both designs, but the O–rings are different.
Notice : Before installation, verify that both O–rings and
fittings have not been nicked or deformed. Deformed or
nicked parts must be replaced. Failure to use the proper
service replacement parts and procedures may result in
excessive refrigerant leakage.
HANDLING REFRIGERANT
CAUTION : Always work in a well–ventilated area and
avoid breathing any refrigerant fumes. If you have dif-
ficulty with breathing, seek medical attention immedi-
ately. If refrigerant comes in contact with any part of
your body, flush the exposed area with water. If a rash
or pain develops, seek medical attention.
Air conditioning systems contain refrigerant. This is a
chemical mixture which requires special handling proce-
dures to avoid personal injury.
Always wear goggles and wrap a clean cloth around the
fittings, the valves and the connections when performing
work that involves opening the refrigerant system. Do not
weld or steam clean on or near any vehicle–installed air
conditioning lines or components.
All refrigerant drums are shipped with a heavy metal screw
cap. The purpose of the cap is to protect the valve and the
safety plug from damage. It is good practice to replace the
cap after each use of the drum.If it is necessary to transport or carry any container of re-
frigerant in a vehicle, do not carry it in the passenger
compartment.
HANDLING OF REFRIGERANT LINES
AND FITTINGS
Notice : Using too low or too high torque when tightening
a fitting can result in loose joints or deformed joint parts.
Both conditions can result in refrigerant leakage.
S Keep all metal tubing lines free of dents or kinks.
Any line restrictions will cause the loss of system
capacity.
S Never bend a flexible hose line to a radius of less
than four times the diameter of the hose.
S Never allow a flexible hose line to come within 65
mm (2–1/2 inches) of the exhaust manifold.
S Inspect flexible hose lines regularly for leaks or
brittleness.
S Replace flexible hose lines with new lines if you find
signs of deterioration or leaking.
S Discharge all refrigerant of the refrigeration system
before disconnecting any fitting in the refrigeration
system.
S Proceed very cautiously regardless of the gauge
readings.
CAUTION : Keep your face and your hands away from
the fitting so that you will not be injured if there hap-
pens to be liquid refrigerant in the line.
S Open the fittings very slowly.
S If you notice pressure when you loosen a fitting,
allow the pressure to bleed off as described under
”Discharging, Adding Oil, Evacuating, and Charging
Procedures for A/C System” in this section.
S Cap or tape any refrigerant line immediately after it
is opened. This will prevent the entrance of mois-
ture and dirt, which can cause internal compressor
wear or plugged lines in the condenser, the evapo-
rator core, the expansion valve, or the compressor
inlet screens.
Important : Use two proper wrenches to connect the O–
ring fittings.
S Back up the opposing fitting to prevent distortion of
the connecting lines or the components.
S Back up both the swagged fitting on the flexible
hose connections and the coupling to which it is
attached with two wrenches to prevent turning the
fitting and damaging the ground seat.
S Keep the O–rings and the seats in perfect condi-
tion. A burr or a piece of dirt may cause a refriger-
ant leak.

CAUTION : Tempering with driver airbag module
creates the risk of an injury from unexpected deploy-
ments. Therefore, the driver airbag module should
never be disassembled.
The driver airbag module is under the center pad of the
steering wheel. The driver airbag module contained an ig-
niter charge and a gas generator to inflate the folded air-
bag.The airbag connector contains a shorting bar, which
makes the circuit shorted when the connector is discon-
nected. The shorting bar prevents current from travelling
through the driver airbag module during servicing. The
shorting bar is disengaged when the connector is con-
nected.

9B – 46ILITHING SYSTEMS
DAEWOO V–121 BL4
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.
