      Tech Tips

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

    2. Check the illumination.

      A002255C01
      *a

      Component without harness connected

      (Steering Pad Switch Assembly)

      		 - -

      1. Connect a positive (+) lead from the auxiliary battery to terminal 5 and a negative (-) lead to terminal 8 of the steering pad switch assembly connector.

      2. Check that the steering pad switch assembly illumination illuminates.

        OK
        The steering pad switch assembly illumination illuminates.

        Tech Tips

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