Pressure-Side Impact Sensor
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 SCM 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-Qualification airbag and the curtain-airbag would be unfolded.
NOTE:
At inspecting the pressure sensor, keep the door airtight for an exact measuring.
