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. |
