REBUILD WARNINGS
Prior to rebuilding a transmission system, the following warnings are to be noted.
Ensure that, before replacing a transmission the cooler lines are flushed out to remove any debris. This can
be done by applying compressed air to the rear cooler line forcing oil and any contaminants out of the front
cooler line.
The cooler flow should be checked after the transmission has been fitted. With the front cooler line connected
and the rear line run into a suitable container, measure the flow over 15 seconds with the vehicle idling in park.
The flow rate should exceed 1 liter in 15 seconds.
Be wary of any situation where water enters the transmission. This may result in fluid foaming and leaking
through the breather.
Ensure that both earth straps (one at the battery terminal and one on the vehicle body) are connected in the
vehicle before connecting the positive side of the battery.
Follow the throttle position calibration procedure in this manual if the engine control module/ transmission
control module (ECM/TCM) is swapped.

8A-2 SEAT BELTS
DESCRIPTION AND OPERATION
DRIVER SEAT BELT WARNING
The driver’s seat belt incorporates a seat belt warning
lamp in the instrument cluster to remind the driver if
the seat belt is not fastened when the ignition is turned
ON. The warning lamp blinks for eight seconds with
chime and goes out.
THREE-POINT FRONT SEAT BELT
WITH PRETENSIONER
The front seat belt contains an electronically controlled
pyrotechnic retractor, pretensioner, which reduces seat
belt slack when it activated in a head-on or angled
front collision. The front seat belt must be replaced
after an accident that causes its activation. At normal
condition the driver’s seat belt operates as emergency
locking retractor (ELR).
Emergency Locking Retractor (ELR)
The ELR seat belt is always unlocked, allowing the
passenger freedom of movement, except in
emergencies such as rapid deceleration, rapid
acceleration, or hard cornering maneuvers.
THREE-POINT REAR OUTBOARD
SEAT BELT
The rear outboard seating position uses the emergency
locking retractor (ELR). Refer to Three-point front seat
belt with pretensioner in this section for details.
TWO-POINT LAP REAR CENTER
SEAT BELT
The two-point lap rear center seat belt is a single contin-
uous length of webbing. The webbing is routed from
the anchor through plate and into a single retractor.
OPERATIONAL AND FUNCTIONAL
CHECKS
Caution:
Keep sharp objects and potentially damaged ob
jects away from seat belts.
Avoid bending or damaging any portion of
buckle or the latch plate
Do not breach or dye the belt webbing. Use only
mild soap and water in order to clean the belts.
When installing the seat belt anchor bolts and
screws, start the bolts and screws by hand in or-
der to prevent cross-threading.
Do not attempt any repairs on the retractor mech-
anisms or covers. Replace any defective assem-
blies with new assemblies.
Replace any belts that are cut or damaged in any
way.
1. Inspect all seat anchor bolts and screws in order to
verify that they are secure.
2. Inspect the seat belt buckle. The buckle must lock
and unlock easily.
3. After inserting the latch into the buckle, tug sharply
on the belt. The buckle must remain locked.
4. Fully extend the shoulder belt portion to make sure
that there is no twisting or tears in the belt.
5. Let the shoulder belt retract fully. The belt should
retract easily.

SUPPLEMENTAL RESTRAINTS SYSTEM 8B-3
SSANGYONG MY2002
SUPPLEMENTAL RESTRAINT
SYSTEM (SRS)
The supplemental restraint system (SRS) is safety de-
vice used in conjunction with the seat belts.
The air bag does not replace the function of the
seatbelt. The driver and the passengers must always
fasten their seat belts adjust them for a proper fit.
The SRS is designed to protect the driver and the front
seat passenger in the event of a significant frontal im-
pact to the vehicle. The airbags deploy if the force is
applied from a direction within about 30 degrees of
the vehicle’s centerline.
The SRS system consists of the following components:
Driver side airbag module.
Passenger airbag module.
Driver’s and passengers front seat belt pretension-
ers.
Sensing and diagnostic module (SDM).
Clock spring.
Wire harness and connectors.
Airbag warning lamp on the instrument cluster.
There are there are for separate four separate deploy-
ment loops in the SRS system. The term “loop” is
used because current leaves the SDM and returns to
the SDM during deployment or testing. First loop is
the circuit from SDM to the driver airbag and back to
the SDM. Second loop is the circuit from the SDM to
the passenger airbag and back to the SDM. The third
and forth loops are for right and left pretensioners.
DESCRIPTION AND OPERATION
KAA8B010
deployment, the system will enter overall or partial
shutdown status and the airbag will not inflate. The
Diagnostic System Check reveals diagnostic trouble
codes (DTCs) through the use of scan tool. It also
checks for proper airbag warning lamp operation.
Battery Voltage Check
The SDM checks the battery voltage continuously and
if the voltage is out of normal operating range (9-16
volts), all system diagnosis stops and turns on the
warning warning lamp.
Deployment Line Check
The SDM checks not only low or high resistance in the
deployment loop but also short to battery or ground
condition to indicates defects in deployment loop. It
indicates the defects by blinking the airbag warning
warning lamp.
Safety Function Check
The SDM checks the operation of arming sensor. If
the arming sensor is shorted more than 2 seconds,
the SDM will enter overall shutdown mode.
AIRBAG MODULES
Driver Airbag Module
Caution: Tampering with driver side airbag module
creates the risk of an injury from unexpected de-
ployment. Therefore, the passenger airbag module
should never be disassembled.
The passenger airbag module is under the center pad
of the steering wheel. The driver airbag module contains
an igniter charge and a gas generator to inflate the
folded airbag.
The airbag contains a shorting bar, which short-circuit
the driver high circuit to driver low circuit when the
connector is disconnected. The shorting bar prevents
current from traveling through the driver airbag module
during servicing. The shorting bar is disengaged when
the connector is connected.
System Control
The sensing and diagnostic module (SDM) continuously
monitors and controls the supplemental restraint
system (SRS) function during ignition ON or driving.
When SDM detects any problem it turns on or blink
the airbag warning lamp and keeps the diagnostic
trouble codes (DTCs). If there is a danger of improper
KAA8B020

SUPPLEMENTAL RESTRAINTS SYSTEM 8B-5
SSANGYONG MY2002
KAA8B060
AIRBAG WARNING LAMP
The instrument cluster contains an airbag warning indi-
cator bulb to verify the operation of the airbag indicator
and sensing and diagnostic module (SDM). The SDM
performs a start-up test when the ignition is turned ON
and turns the airbag indicator on for 4.5 seconds by
supplying an internal ground to the indicator lamp
circuit. After 4.5 seconds, the airbag indicator will turn
off if no more malfunctions have been detected.
If the SDM has detected malfunctions, which could
potentially affect the operation of the supplemental
restraint system (SRS) it turns on or blinks the airbag
warning indicator. The airbag indicator stays on for
the malfunction of internal system and blinks for
external circuit problem such as short to battery or
ground. The airbag indicator blinks four different modes
according to the fault.
Some malfunctions could result in non-deployment
when necessary or deployment under conditions which
would no normally result in deployment.
When the SDM is not properly attached to its connector
the airbag circuit is shorted to ground because there
is a shorting bar within the SDM electronic connector.
The shorting bar is disengaged when proper connection
is made, but if a poor connection exists the SDM
connector supplies a ground to the airbag indicator in
dependently of the SDM, and the airbag indicator turns
on.
CLOCK SPRING
Caution: Disassembling the clock spring can cause
injury or cause the clock spring to malfunction.
Caution: Over-rotating the clock spring without the
steering wheel in position could damage the clock
spring and result in an inoperative driver airbag.There is a coil assembly in the steering which is referred
to as a clock spring because of its internal resemblance
to the type of spring used in a mechanical clock. The
clock spring should never be disassembled, and there
is no timekeeping function. The clock spring contains
current- carrying coils. One of the current-carrying coils
maintains continuous contact within the driver deploy-
ment loop while the steering wheel is rotated. The clock
spring also contains coils that maintain continuous con-
tact for horn and remote audio control switch.
Turning the steering wheel in one direction tightens
the coil, and turning the steering wheel in the opposite
direction loosens the coil. Do not turn the clock spring
when the steering wheel is not attached.
A yellow two-way connector on the lower steering col-
umn is attached to the clock spring wiring.
WIRING HARNESS CONNECTORS
If the sensing and diagnostic module (SDM) electrical
connector 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:
The clock spring electrical connector at the lower
steering column.
The passenger airbag module.
The driver airbag module.
The seat belt pretensioners.
The SDM connector.
The shorting bar is only a backup safety device. Always
disable the supplemental restraints system (SRS) be-
fore beginning any service procedure.

DIAGNOSTIC INFORMATION AND PROCEDURES
DIAGNOSTIC TROUBLE CODES
(DTC)
When the sensing and diagnosticmodule (SDM)
detects any problem it illuminates or blinks the airbag
warning indicator and keeps the diagnostic trouble
codes (DTCs). The supplemental restraint system
(SRS) Diagnostic System Check must always be the
starting point for any SRS diagnosis. The SRS
Diagnostic System Check reveals DTCs through the
use of scan tool. It also checks for proper airbag
warning lamp operation.
The two types of DTCs that may be recorded are as
follows:
1. Current DTCs represent malfunction currently being
detected. Current DTCs are stored in random
access memory (RAM).
2. Historic DTCs represent malfunctions detected since
the last time the historic memory was cleared.
Historic DTCs are stored in the electrically erasable
programmable read-only memory (EEPROM).
The DTC is differentiates internal and external faults
upon the cause of the defects. Internal faults can not
be cured, replace the SDM. Refer to “Diagnostic
Trouble Code Table” in this section.
SCAN TOOL DIAGNOSTICS
A scan tool can read serial data from terminal 9 of the
data link connector (DLC). The scan tool is used to
read diagnostic trouble codes (DTCs), and to clear
some DTCs after a repair is completed. By design,
certain codes cannot be cleared.
To use the scan tool, turn the ignition OFF, connect
the scan tool to the DLC, and turn the ignition switch
to ON. Follow the instructions in the scan tool manual.
The SDM sends serial data from terminal 20 of the
SDM to terminal 9 of the DLC.
USE OF SPECIAL TOOLS
Use a scan tool to read and clear diagnostic trouble
codes (DTCs). A connector adapter kit provides
jumper wires and terminal adapters to make it easier
to test small terminals. In diagnostic testing, use load
tool or dummy resistance to substitute for airbag
modules.

SRS Diagnostic System Check
Caution: the sensing and diagnosis module (SDM)
can maintain sufficient voltage to deploy the airbags
and pretensioners for 0.15 seconds after the ignition
is OFF and the fuse has been removed. If the airbags
or pretensioners are not disconnected, do not begin
service until one minute has passed after
disconnecting power to the SDM. Otherwise, injury
could result.Caution: During service procedure, be very careful
when handling the SDM. Never strike or jar the SDM.
Never power the supplemental restraints system
(SRS) when the SDM is not rigidly attached to the
vehicle. Also SDM mounting nuts must be carefully
tightened to ensure proper operation of the SRS.
The SDM could be activated if it is powered when it
is not rigidly attached to the vehicle, resulting in
unexpected deployment and possible injury.
