Front Impact Sensor(FIS)located at both sides of the front of engine room detects head-on collision.
When FIS delivers collision signal to SRSCM, SRSCM checks if safing sensor located in SRSCM detects collusion.
and if both FIS and safing sensor detects collision simultaneously, SRSCM operates front air bag.
If you strike or spin the SRSCM at the IG “ON” state, the seat-belt pretensioner, curtain-airbag or side-airbag could be unfolded and bring on danger. Handle it with care.
The SRSCM sets DTC B1335 if PFIS with wrong ID is detected.
