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

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

Passenger Airbag Module

Caution: Tampering with passenger airbag module
creates the risk of an injury from unexpected
deployment. Therefore, the passenger airbag
module should never be disassembled.

The passenger airbag module is on the passenger of
the instrument panel. The passenger 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 passenger high circuit to passenger low circuit when
the connector is disconnected. The shorting bar pre-
vents current from traveling through the passenger air-
bag module during servicing. The shorting bar is
disengaged when the connector is connected.

FRONT SEAT BELT PRETENSIONERS

Caution: Tampering with seat belt pretensioner
creates the risk of an injury from unexpected
deployment. Therefore, the seat belt pretensioner
should never be disassembled.

The seat belt pretensioners are assembled with each
front seat belt retractor to retract the seat belt webbing
when accounted a frontal collision. The seat belt preten-
tioners are controlled by sensing and diagnostic
Module (SDM).

The seat belt pretensioner contains an igniter charge
and a gas generator to pull the seat belt webbing. The
seat belt pretensioner must be replaced after an acci-
dent that causes its activation.

The seat belt pretensioner also contains a shorting bar
to prevent current from traveling through the seat belt
pretensioner during servicing. The shorting bar is
disengaged when the connector is connected.

SENSING AND DIAGNOSTIC
MODULE (SDM)

Caution: During the service procedures, be careful
when handling the SDM. Never shake or jar the
SDM. Never apply power to SRS when the SDM is
not rigidly attached to the vehicle. All SDM
mounting nuts and grounding nut must be fully
tightened. Failures to follow these precautions could
cause deployment and results in personal injury.

The SDM located on floor beneath the instrument panel.
The SDM performs the following functions:

•

Monitors the supplemental restraint system (SRS)
electrical components and sets a diagnostic trouble
code (DTC) when malfunction is detected.

•

Displays SRS diagnostic trouble codes and system
status information when connected to a scan tool.

•

Illuminates the airbag indicator to alert the driver to
any fault.

•

Provides a reserve power source to deploy the air-
bags and pretensioners if an accident has disabled
the normal power source.

•

Monitors vehicle velocity changes to detect frontal
impacts, which are severe enough to warrant deployment.

•

Causes current to flow through the airbag modules
and pretensioner to cause deployment if a frontal
impact of sufficient force is detected.

The SDM contains no user-serviceable parts.
