DTC B1409-00: SIS (Side Impact Sensor) Front-Driver Communication Error: General Description
Pressure-Side Impact Sensor and Side Impact Sensor are installed in the left and the right side of front door and in the lower of B-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 SRSCM detects the impact signals of the Pressure-Side Impact Sensor and 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.
