Hyundai Sonata: General Information
General Information
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.
