B1742 P-SIS Front-Driver Communication Error

General Information

Component Location





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 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.

DTC Description

The SRSCM sets DTC B1742 if there is any error in communication between Pressure-Side Impact (Driver) and SRSCM.
