        Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.

      • B006P0Z

        If this procedure is performed without disconnecting the negative (-) terminal of the battery, the airbag may deploy even if an impact is applied only to the front airbag sensor LH. Therefore, make sure that the negative (-) terminal of the battery is disconnected before performing this procedure.

    3. Disconnect the airbag connector.

      Note

      When disconnecting any airbag connector, take care not to damage the airbag wire harness.


      1. Push down the housing lock and slide the CPA. (At this time, the connector cannot be disconnected yet.)
