      (Steering Pad Switch Assembly)

      		 - -

      1. Connect a positive (+) lead from the battery to terminal z1-1 (ILL+2) and a negative (-) lead to terminal z1-6 (ILL-2) 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.
