Code B1745 Hyundai Description

Pressure-Side Impact Sensor and Rear Side Impact Sensor are installed in the left and the right side of the front door and in the lower of C-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 System Control Module (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.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service

Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.

Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
