The SRSCM is supported in connection with the front airbag function by the two front impact sensors, which act as
intelligent acceleration sensors and as such back up the central airbag controller. Both the front impact sensors
continuously report the current system status of the vehicle to the SRSCM.
If one of the two front impact sensor reports an acceleration level, the SRSCM must verify the acceleration signal
internally by means of a suitable plausibility check. The SRSCM does not release the appropriate airbag unless the
result of this verification is positive.
