  1. HANDLING OF A VEHICLE THAT HAS BEEN DAMAGED IN A COLLISION


    1. Refer to the TOYOTA Repair Manual for the SRS airbag system inspection procedures.

    2. If impacts are likely to occur to the front airbag sensors, front floor side airbag sensor, door side airbag sensors, rear airbag sensors, No.2 side airbag sensor assemblies or airbag ECU assembly remove each sensor as necessary beforehand.

    3. Do not allow the front airbag sensors, front floor side airbag sensor, door side airbag sensors, rear airbag sensors, No.2 side airbag sensor assemblies or airbag ECU assembly to become heated to high temperatures.

    4. Check the wire harnesses and connectors for damage and/or melting, as some areas of the airbags and seat belt pretensioners may heat up to several hundred degrees when they operate.

        • Disconnect all the malfunctioning circuit connectors.

        • Disconnect the airbag ECU assembly connector.

      2. If DTCs are NOT displayed:
