      • *2: w/ Voice Switch

      • *3: w/ Panoramic View Monitor System

      Tech Tips

      If the result is not as specified, replace the steering pad switch assembly.

    2. Check the illumination.

      *a

      Component without harness connected

      (Steering Pad Switch Assembly)

      - -

      1. Connect a positive (+) lead from the battery to terminal 1 (IL+2) and a negative (-) lead to terminal 8 (EAU) of the steering pad switch assembly connector.

      2. Check that the switch illumination illuminates.

        OK
        The steering pad switch illumination illuminates.

        Tech Tips

        If the result is not as specified, replace the steering pad switch assembly.
