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. |
