| 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 a folded cushion assembled with
an inflator unit ; side airbag modules located in the front seat contain
a folded cushion and an inflator unit ; curtain airbag modules located
inside the headliner contains folded cushions and inflator units. The
impact sensing function of the SRSCM is carried out by an electronic
accelerometer that continuously measures 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 a front impact sensor,
and side impact with a side impact sensor to determine airbag module
deployment.
| 1. |
DC/DC converter: DC/DC converter in the 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 a separate back up power
supply, that will supply deployment energy instantly in low voltage
condition or upon power failure by a frontal 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: When an error is detected, the module
will transmit a signal to the SRSCM indicator lamp located on the
cluster. MIL lamp will notice the driver of SRS error. Upon ignition key
on, SRS lamp will turn on for about six seconds. |
| 5. |
Trouble code registration: When an error occur in the system,
SRSCM will store a 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 clearing should not happen. |
| 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, SRSCM should not be used again but replaced. |
| 8. |
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. |
| 9. |
Side airbag deployment will be determined by the SRSCM that
detects satellite sensor impact signal upon a side crash, irrespective
to the seat belt condition. |
