tions. With the ignition ON and the engine not running,
the Engine Control Module (ECM) will read the manifold
pressure as barometric pressure and adjust the air/fuel
ratio accordingly. This compensation for altitude allows
the system to maintain driving performance while hold-
ing emissions low. The barometric function will update
periodically during steady driving or under a wide open
throttle condition. In the case of a fault in the barometric
portion of the MAP sensor, the ECM will set to the de-
fault value.
A failure in the MAP sensor circuit sets a diagnostic
trouble codes P0107, P0108 or P0106.
ENGINE CONTROL MODULE
The Engine Control Module (ECM), is the control center
of the fuel injection system. It constantly looks at the in-
formation from various sensors and controls the sys-
tems that affect the vehicle’s performance. The ECM
also performs the diagnostic functions of the system. It
can recognize operational problems, alert the driver
through the Malfunction Indicator Lamp (MIL), and store
diagnostic trouble code(s) which identify the problem
areas to aid the technician in making repairs.
There are no serviceable parts in the ECM. The calibra-
tions are stored in the ECM in the Programmable Read
Only Memory (PROM).
The ECM supplies either 5 or 12 volts to power the sen-
sors or switches. This is done through resistance in the
ECM which are so high in value that a test light will not
come on when connected to the circuit. In some cases,
even an ordinary shop voltmeter will not give an accu-
rate reading because its resistance is too low. You must
use a digital voltmeter with a 10 megohm input imped-
ance to get accurate voltage readings. The ECM con-
trols output circuits such as the fuel injectors, the Idle Air
Control (IAC) valve, the A/C clutch relay, etc., by control-
ling the ground circuit through transistors or a device
called a “quad-driver.”
FUEL INJECTOR
The Multi-port Fuel Injection (MFI) assembly is a sole-
noid-operated device controlled by the Engine Control
Module (ECM) that meters pressurized fuel to a single
engine cylinder. The ECM energizes the fuel injector or
solenoid to a normally closed ball or pintle valve. This al-
lows fuel to flow into the top of the injector, past the ball
or pintle valve, and through a recessed flow director
plate at the injector outlet.
The director plate has six machined holes that control
the fuel flow, generating a conical spray pattern of finely
atomized fuel at the injector tip. Fuel from the tip is di-
rected at the intake valve, causing it to become further
atomized and vaporized before entering the combustion
chamber. A fuel injector which is stuck partially open
would cause a loss of fuel pressure after the engine is
shut down. Also, an extended crank time would be no-
ticed on some engines. Dieseling could also occur be-cause some fuel could be delivered to the engine after
the ignition is turned off.
FUEL CUT-OFF SWITCH
The fuel cutoff switch is a safety device. In the event of a
collision or a sudden impact, it automatically cuts off the
fuel supply and activates the door lock relay. After the
switch has been activated, it must be reset in order to
restart the engine. Reset the fuel cutoff switch by press-
ing the rubber top of the switch. The switch is located
near the right side of the passenger’s seat.
KNOCK SENSOR
The knock sensor detects abnormal knocking in the en-
gine. The sensor is mounted in the engine block near the
cylinders. The sensor produces an AC output voltage
which increases with the severity of the knock. This sig-
nal is sent to the Engine Control Module (ECM). The
ECM then adjusts the ignition timing to reduce the spark
knock.
VARIABLE RELUCTANCE (VR)
SENSOR
The variable reluctance sensor is commonly refered to
as an “inductive” sensor.
The VR wheel speed sensor consists of a sensing unit
fixed to the left side front macpherson strut, for non-ABS
vehicle.
The ECM uses the rough road information to enable or
disable the misfire diagnostic. The misfire diagnostic
can be greatly affected by crankshaft speed variations
caused by driving on rough road surfaces. The VR sen-
sor generates rough road information by producing a
signal which is proportional to the movement of a small
metal bar inside the sensor.
If a fault occurs which causes the ECM to not receive
rough road information between 30 and 70 km/h (1.8
and 43.5 mph), Diagnostic Trouble Code (DTC) P1391
will set.
OCTANE NUMBER CONNECTOR
The octane number connector is a jumper harness that
signal to the engine control module (ECM) the octane
rating of the fuel.
The connector is located on the next to the ECM. There
are two different octane number connector settings
available. The vehicle is shipped from the factory with a
label attached to the jumper harness to indicate the oc-
tane rating setting of the ECM. The ECM will alter fuel
delivery and spark timing based on the octane number
setting. The following table shows which terminal to
jump on the octane number connector in order to
achieve the correct fuel octane rating. Terminal 2 is
ground on the octane number connector. The find the

DIAGNOSTIC INFORMATION AND PROCEDURES
GENERAL DIAGNOSIS
TESTING THE REFRIGERANT
SYSTEM
If you suspect a problem in the refrigerant system,
check for the following conditions:
1. Check the outer surfaces of the radiator and the con-
denser cores to be sure that the airflow is not blocked
by dirt, leaves, or other foreign material. Check be-
tween the condenser and the radiator, as well as all
outer surfaces.
2. Check for restrictions or kinks in the condenser core,
the hoses, and the tubes.
3. Check the operation of the blower fan.
4. Check all the air ducts for leaks or restrictions. A low
airflow rate may indicate a restricted evaporator core.
5. Check for slippage of the compressor clutch.
6. Check the drive belt tension.
INSUFFICIENT COOLING “QUICK
CHECK” PROCEDURE
Perform the following “hand-feel” procedure to get a
quick idea of whether the air conditioning (A/C) system
has the proper charge of Refrigerant-134a.
1. Warm up the engine. Run the engine at idle.
2. Open the hood and all the doors.
3. Turn the A/C switch ON.
4. Set the temperature control to the full cold position.
5. Set the blower speed switch on 4.
6.“Hand-feel” the temperature of the evaporator outlet
pipe. The pipe should be cold.
7. Check for other problems. Refer to “Testing the Re-
frigerant System” in this section.
8. Leak check the system. Refer to “Leak Testing the
Refrigerant System” in this section. If you find a leak,
discharge the system and repair the leak as required.
After completing the repair, evacuate and charge the
system.
9. If there is no leak, refer to “Insufficient Cooling Diag-
nosis” in this section.

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.

DIAGNOSTIC INFORMATION AND PROCEDURES
WINDNOISE DIAGNOSIS
Caution: An assistant should drive the vehicle while
the technician checks for the location of the wind-
noise, in order to prevent personal injury or vehicle
damage.
A test drive in the vehicle is necessary to accurately de-
termine the location of the windnoise. Often there is a
primary leak and secondary leaks. Failure to repair all
leaks will only reduce the windnoise, not eliminate it.
During the test drive the technician should bring the fol-
lowing items to aid in determining the location of the
windnoise.

A mechanics stethoscope or vacuum hose

Masking tape

Strip caulk

A china marking pencil

A screwdriver
Perform the following steps in order to conduct the road
test:
1. Choose a route that includes smooth straight streets
that run in all four directions (north, south, east, and
west).
2. Choose streets with little traffic or noise that would in-
terfere with the test.
3. Drive the vehicle at the speeds at which the noise
was noticed by the customer or until the noise is pro-
duced. Do not exceed legal speed limits.
4. The windnoise is external if any of the following condi-
tions occur:

The windnoise is caused by the wind.

The windnoise can be heard with the door glass
lowered and while the vehicle is being driven.

The windnoise is eliminated when tape is placed
over various moldings and gaps.5. Internal windnoise is air leaving the vehicle and
should be repaired in the following manner.

In order to locate the leak, tape off the body lock
pillar pressure relief valves. This will cause air
pressure to build up inside the vehicle and en-
hance the windnoise.

Use a stethoscope or a vacuum hose to locate the
leak.

Temporarily repair the leak with masking tape.
D109A307

Continue testing in order to determine if the noise
has been eliminated or if other leaks exist.

When all leaks have been found, return to the shop
and make permanent repairs with the proper align-
ment techniques and sealing materials.

DESCRIPTION AND OPERATION
DOOR LOCK STRIKER
The front and the rear door lock strikers each consist of
a striker with two screws threaded into a floating cage
plate in the B-pillars and C-pillars. The door is secured in
the closed position when the door lock fork snaps over
and engages the striker.
CHILDPROOF REAR DOOR LOCK
The childproof rear door locks help prevent passengers,
especially children, from opening the rear doors of the
vehicle from the inside.
In order to activate these locks, move the levers of both
rear doors to the lock position. Then, close both doors.
Rear passengers will be unable to open the doors from
the inside of the vehicle.
In order to deactivate the childproof rear door lock, un-
lock the door from the inside of the vehicle and open the
door from the outside. Move the lever to the unlock posi-
tion. The rear door will now work normally.
POWER DOOR LOCKS
The power door locks use a solenoid that is contained in
each door lock assembly. The door locks are activatedby the actuator on the inside door handle or by the lock
cylinder on the driver door only. When the driver door is
locked or unlocked by the actuator or lock cylinder, all
doors are locked or unlocked accordingly.
POWER WINDOWS
The power windows are controlled by electrical switches
on the front door tirm and operated by a motor at each
window regulator. The windows are lowered by pressing
the switch and raised by pulling up on the switch. The
window will stop movement when the switch is released
or when the window is completely open or closed.
TAILGATE STRUT
This vehicle is equipped with the gas struts. The struts
support the tailgate suitably when opening the tailgate.
The strut contained the high pressure compressed gas.
Therefore, be careful not to take apart, puncture, apply
heat or fire bacause the strut may explode.
