DTC B1412-00: SIS (Side Impact Sensor) Rear-Driver Communication Error: General Description
Pressure-Side Impact Sensor (P-SIS) and Side Impact Sensor (SIS) are installed in the left and the right side of rear door and in the lower of C-pillar respectively.
The P-SIS 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 SRSCM detects the impact signals of the P-SIS and SIS and compares with signals of the safe sensor inside. If the signals of all sensors are judged as a collision, the side airbag (SAB) and the curtain airbag (CAB) would be unfolded.
