| 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 front 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, to 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. |
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. |
| 3. |
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 GDS. |
| 4. |
Airbag warning lamp on: Upon detecting error, the module will
transmit signal to SRSCM indicator lamp located at cluster. MIL lamp
will indicate to the driver of SRS error. Upon ignition key on, SRS lamp
will turn on for about six seconds. |
| 5. |
Trouble code registration: Upon error occurrence in system,
SRSCM will store DTC corresponding to the error. DTC can be cleared only
by GDS. However, if an internal fault code is logged or if a crash is
recorded, the fault code(s) cannot be cleared. |
| 6. |
Self diagnostic connector: Data stored in SRSCM memory will
be output to GDS or other external output devices through connector
located below driver side crash pad. |
| 7. |
Once airbag is deployed. The SRSCM should not be used again and should be replaced. |
| 8. |
SRSCM will determine whether passenger put on the seat belt
by the signal from built-in switch in the seat belt buckle, and deploy
front seat airbag at each set of crash speed. |
| 9. |
Side airbag deployment will be determined by SRSCM that
detects satellite sensor impact signal upon a side crash, irrespective
to seat belt condition. |
