General
The supplemental restraint system (SRS) is designed to supplement the seat belt to help reduce the risk or severity of
injury to the driver and passenger by activating and deploying the driver, passenger, side airbag and belt pretensioner
in certain frontal or side collisions.
The SRS (Airbag) consists of : a driver side airbag module located in the center of the steering wheel, which contains
the folded cushion and an inflator unit ; a passenger side airbag module located in the passenger side crash pad
contains the folded cushion assembled with inflator unit ; side airbag modules located in the driver and passenger seat
contain the folded cushion and an inflator unit ; curtain airbag modules located inside of the headliner which contains
folded cushions and inflator units. The impact sensing function of the SRSCM is carried out by electronic
accelerometer that continuously measure the vehicle's acceleration and delivers a corresponding signal through
amplifying and filtering circuitry to the microprocessor.
SRSCM (SRS Control Module)
SRSCM will detect front impact with front impact sensor, and side impact with side impact sensor, and determine
airbag module deployment.
1. DC/DC converter: DC/DC converter in power supply unit includes up/down transformer converter, and provide
ignition voltage for 2 front airbag ignition circuits and the internal operation voltage of the SRSCM. If the internal
operation voltage is below critical value setting, it will perform resetting.
2. Safety sensor: Safety sensor is located in airbag ignition circuit. Safety sensor will operate airbag circuit at any
deployment condition and release airbag circuit safely at normal driving condition. Safety sensor is a double contact
electro - mechanical switch that will close detecting deceleration above certain criteria.
3. Back up power supply: SRSCM has separate back up power supply, that will supply deployment energy instantly in
low voltage condition or upon power failure by front crash.
4. Self diagnosis: SRSCM will constantly monitor current SRS operation status and detect system failure while vehicle
power supply is on, system failure may be checked with trouble codes using scan tool. (Hi- Scan)
5. Airbag warning lamp on: Upon detecting error, the module will transmit signal to SRSCM indicator lamp located at
cluster. MIL lamp will indicate driver SRS error. Upon ignition key on, SRS lamp will turn on for about six seconds.
6. Trouble code registration: Upon error occurrence in system, SRSCM will store DTC corresponding to the error.
DTC can be cleared only by Hi - Scan. However, if an internal fault code is logged or if a crash is recorded the fault
clearing should not happen.
7. Self diagnostic connector: Data stored in SRSCM memory will be output to Hi - Scan or other external output
devices through connector located below driver side crash pad.
8. Once airbag is deployed, SRSCM should not be used again but replaced.
9. SRSCM will determine whether passenger put on seat belt by the signal from built- in switch in seat belt buckle, and
deploy front seat airbag at each set crash speed.
10. Side airbag deployment will be determined by SRSCM that will detect satellite sensor impact signal upon side
crash, irrespective to seat belt condition.

AIRBAG DISPOSAL
SPECIAL TOOL REQUIRED
Before scrapping any airbags or side airbags (including those in a whole vehicle to be scrapped), the airbags or side
airbags must be deployed. If the vehicle is still within the warranty period, before deploying the airbags or side airbags,
the Technical Manager must give approval and/or special instruction. Only after the airbags or side airbags have been
deployed (as the result of vehicle collision, for example), can they be scrapped.
If the airbags or side airbags appear intact (not deployed), treat them with extreme caution. Follow this procedure.
DEPLOYING AIRBAGS IN THE VEHICLE
If an SRS equipped vehicle is to be entirely scrapped, its airbags or side airbags should be deployed while still in the
vehicle. The airbags or side airbags should not be considered as salvageable parts and should never be installed in
another vehicle. 1. Turn the ignition switch OFF, and disconnect the battery negative cable and wait at least three minutes.
2. Confirm that each airbag or side airbag is securely mounted.
3. Confirm that the special tool is functioning properly by following the check procedure.
DRIVER'S AIRBAG :
1.Remove the driver's airbag and install the SST(0957A - 38500).
2. Install the driver's airbag on the steering wheel.
FRONT PASSENGER'S AIRBAG :
1.Remove the glove box, then disconnect the 2P connector between the front passenger's airbag and SRS main
harness.
2. Install the SST(0957A - 3F100).
SIDE AIRBAG :
1.Disconnect the 2P connector between the side airbag and side wire harness.
2. Install the SST (0957A- 3F100).
CURTAIN AIRBAG :
1.Disconnect the 2P connector between the curtain airbag and wire harness.
2. Install the SST(0957A - 38500).
SEAT BELT PRETENSIONER :
1.Disconnect the 2P connector from the seat belt pretensioner.
2. Install the SST(0957A - 38500).
3. Place the deployment tool at least thirty feet (10 meters) away from the airbag.
4. Connect a 12 volt battery to the tool.
5. Push the tool's deployment switch. The airbag should deploy (deployment is both highly audible and visible: a loud
noise and rapid inflation of the bag, followed by slow deflection)
6. Dispose of the complete airbag. No part of it can be reused. Place it in a sturdy plastic bag and seal it securely.

DESCRIPTION
Driver Airbag (DAB) is installed in steering wheel and electrically connected to SRSCM via clockspring. It protects the
driver from danger by deploying a bag when frontal crash occurs. The SRSCM determines deployment of Driver Airbag
(DAB).
Never attempt to measure the circuit resistance of the airbag module (squib) even if you are using the specified
tester. If the circuit resistance is measured with a tester, accidental airbag deployment will result in serious
personal injury.

Tightening Torque (DAB Mounting Bolt)
: 0.8 ~ 1.1 kgf.m (7.9 ~ 10.8 Nm, 5.8 ~ 8.0 lb.ft)
8.Connect the battery negative cable.
9. After installing the airbag, confirm proper system operation:
a. Turn the ignition switch ON; the SRS indicator light should be turned on for about six seconds and then go off.
b. Make sure horn button works.
INSPECTION
Driver Airbag (DAB)
If any improper parts are found during the following inspection, replace the airbag module with a new one.
Never attempt to measure the circuit resistance of the airbag module (squib) even if you are using the specified
tester. If the circuit resistance is measured with a tester, accidental airbag deployment will result in serious
personal injury.
1. Check pad cover for dents, cracks or deformities.
2. Check the airbag module for denting, cracking or deformation.
3. Check hooks and connectors for damage, terminals for deformities, and harness for binds.

4.Check airbag inflator case for dents, cracks or deformities.
5.Install the airbag module to the steering wheel to check for fit or alignment with the wheel.
Clockspring
1.If, as a result of the following checks, even one abnormal point is discovered, replace the clock spring with a new
one.
2. Check connectors and protective tube for damage, and terminals for deformities.

DESCRIPTION
The Seat Belt Pretensioners (BPT) are installed inside Center Pillar (LH & RH). When a vehicle crashes with a certain
degree of frontal impact, the pretensioner seat belt helps to reduce the severity of injury to the front seat occupants by
retracting the seat belt webbing. This prevents the front occupants from thrusting forward and hitting the steering
wheel or the instrument panel when the vehicle crashes.
Never attempt to measure the circuit resistance of the Seat Belt Pretensioner (BPT) even if you are using the
specified tester. If the circuit resistance is measured with a tester, the pretensioner will be ignited accidentally.
This will result in serious personal injury.

DESCRIPTION
The Seat Belt Buckle Pretensioners (BUPT) are installed in the right side of the driver seat and the left side of the
passenger seat. When a vehicle crashes with a certain degree of frontal impact, the seat belt buckle pretensioner
helps to reduce the severity of injury to the front seat occupants by retracting the seat belt buckle. This prevents the
front occupants from thrusting forward and hitting the steering wheel or the instrument panel when the vehicle crashes.
Never attempt to measure the circuit resistance of the Seat Belt Buckle Pretensioner (BUPT) even if you are
using the specified tester. If the circuit resistance is measured with a tester, the pretensioner will be ignited
accidentally. This will result in serious personal injury.
