Code B1625 Toyota Description

The Side Collision Sensor Left (LH) circuit (to determine deployment of the Front Seat Side Airbag Assembly LH and Curtain Shield Airbag Assembly LH) is composed of the Center Airbag Sensor Assembly, Side Airbag Sensor LH and Rear Airbag Sensor LH. The Side Airbag Sensor LH detect impacts to the vehicle and send signals to the Center Airbag Sensor Assembly to determine if the airbag should be deployed. The Diagnostic Trouble Code (DTC) B1625 is stored when a malfunction is detected in the Side Airbag Sensor LH.

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.
