DTC B1739-00: P-SIS (Side Impact Sensor, Pressure) Front-Driver Defect: General Description
The Pressure-Side Impact Sensor (PSIS) and Side Impact Sensor (SIS) 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 acceleration during collision. Unlike the conventional acceleration sensor, the Pressure Sensor senses an air pressure in damaged door when 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 determine a collision, the side-airbag and the curtain-airbag would deploy.
NOTE:
At inspecting the pressure sensor, keep the door airtight for an exact measuring.
