General
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 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 will not clear.
|
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 can not be reused ; must be replaced.
|
8. |
Side airbag deployment will be determined by SRSCM that will detect
satellite sensor impact signal upon side crash, irrespective to seat
belt condition.
