Airbag(Event #1)
B1412 SIS(Side Impact Sensor)Rear-Driver Communication error - General Information

Component Location





General Description

Pressure-Side Impact Sensor and Rear Side Impact Sensor are installed in the left and the right side of front door and in the lower of C-pillar respectively.
The Pressure-Side Impact Sensor senses an impact based on an acceleration at crashing. Unlike the conventional acceleration sensor, the Pressure Sensor senses an air pressure by a distorted door at crashing and measures an impact.
The SCM detects the impact signals of the Pressure-Side Impact Sensor and Rear Side Impact Sensor and compares with signals of the safe sensor inside. If the signals of all sensors are judged as a collision, the side-airbag and the curtain-airbag would be unfolded.

NOTE:
At inspecting the pressure sensor, keep the door airtight for an exact measuring.

NOTE:
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.

DTC Description

The SRSCM sets DTC B1412 if there is any error in communication between RDSIS and SRSCM.
