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

      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.)
