c.Store the removed airbag on secure, flat surface away from any high heat source (exceeding 85°C/185°F).
d. Never perform electrical inspections to the airbags, such as measuring resistance.
e. Do not position yourself in front of the airbag assembly during removal, inspection, or replacement.
f. Refer to the scrapping procedures for disposal of the damaged airbag.
g. Be careful not to bump or impact the SRS unit or the side impact sensors whenever the ignition switch is ON, wait
at least three minutes after the ignition switch is turned OFF before begin work.
h. During installation or replacement, be careful not to bump (by impact wrench, hammer, etc.) the area around the
SRS unit and the side impact sensor. The airbags could accidentally deploy and cause damage or injury.
i. After a collision in which the airbags were deployed, replace the front airbags and the SRS unit. After a collision in
which the side airbag was deployed, replace the side airbag, the front impact sensor and side impact sensor on
the side where the side airbag deployed and the SRS unit. After a collision in which the airbags or the side air
bags did not deploy, inspect for any damage or any deformation on the SRS unit and the side impact sensors. If
there is any damage, replace the SRS unit, the front impact sensor and/or the side impact sensors.
j. Do not disassemble the SRS unit, the front impact sensor or the side impact sensors
k. Turn the ignition switch OFF, disconnect the battery negative cable and wait at least three minutes before
beginning installation or replacement of the SRS unit.
l. Be sure the SRS unit, the front impact sensor and side impact sensors are installed securely with the mounting
bolts.
m. Do not spill water or oil on the SRS unit,or the front impact sensor or the side impact sensors and keep them
away from dust.
n. Store the SRS unit, the front impact sensor and the side impact sensors in a cool (less than 40°C/104°F) and dry
(less than 80% relative humidity, no moisture) area.
Wiring Precautions
SRS wiring can be identified by special yellow outer covering (except the SRS circuits under the front seats).
Observe the instructions described in this section.
a. Never attempt to modify, splice, or repair SRS wiring.
If there is an open or damage in SRS wiring, replace the harness.

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.

b. Deployed airbag(s)
c. Seat belt pretensioner(s)
d. Front impact sensors
e. SRS wiring harnesses
f. Inspect the clock spring for heat damage.
If any damage found, replace the clock spring.
When the seat belt pretensioner(s) deployed after a collision, replace the following items. a. Seat belt pretensioner(s)
b. SRSCM (if B1658 detected)
c. Front impact sensors
d. SRS wiring harnesses
When the side/curtain airbag(s) deployed after a collision, replace the following items. a. SRSCM
b. Deployed airbag(s)
c. Side impact sensor(s) for the deployed side(s)
d. SRS wiring harnesses
After the vehicle is completely repaired, confirm the SRS airbag system is OK. a. Turn the ignition switch ON, the SRS indicator should come on for about 6 seconds and then go off.

DESCRIPTION
The primary purpose of the SRSCM (Supplemental Restraints System Control Module) is to discriminate between an
event that warrants restraint system deployment and an event that does not. The SRSCM must decide whether to
deploy the restraint system or not. After determining that pretensioners and/or airbag deployment is required, the
SRSCM must supply sufficient power to the pretensioners and airbag igniters to initiate deployment. The SRSCM
determines that an impact may require deployment of the pretensioners and airbags from data obtained from impact
sensors and other components in conjunction with a safing function. The SRSCM will not be ready to detect a crash or
to activate the restraint system devices until the signals in the SRSCM circuitry stabilize. It is possible that the SRSCM
could activate the safety restraint devices in approximately 2 seconds but is guaranteed to fully function after prove-
out is completed. The SRSCM must perform a diagnostic routine and light a system readiness indicator at key - on. The
system must perform a continuous diagnostic routine and provide fault annunciation through a warning lamp indicator
in the event of fault detection. A serial diagnostic communication interface will be used to facilitate servicing of the
restraint control system.
