Hyundai Creta: General Information / General information
| General Information |
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 sensors and internal acceleration
sensors inside of SRSCM. For side impact, SRSCM will detect the side impact
with 2 side impact sensors, 2 conventional acceleration sensors in Center pillar
inner locations, and internal acceleration sensor inside of SRSCM.
SRSCM is designed to issue corresponding airbag module(s) deployment(s) using
above described sensor inputs.
| 1. |
DC/DC converter : DC/DC converter in power supply unit includes up/down
transformer converter, and provides ignition voltage for all firing
circuits, implemented as ASICs and the internal operation voltage of
the SRSCM itself. 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 indicat
to the driver that there is an 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 active or if a crash is recorded
the fault clearing cannot be performed.
|
| 6. |
Self diagnostic connector : Data stored in SRSCM memory will be output
to GDS or other external output devices through a 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 fasten the 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 SRSCM that will detect
satellite sensor impact signal upon side crash, irrespective to seat
belt condition.
