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

  1. Check the illumination.

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

    2. Check that the switch illumination comes on.

      OK:
      Steering pad switch illumination comes on.
      If the result is not as specified, replace the steering pad switch assembly.
