    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, rear airbag sensors, side airbag sensors, seat position airbag sensor or airbag sensor assembly remove each sensor as necessary beforehand.

    3. Do not allow the front airbag sensors, rear airbag sensors, side airbag sensors, seat position airbag sensor or airbag sensor 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.
