      Tech Tips

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

    2. Check the illumination.

      		 - -

      1. Connect a positive (+) lead from the auxiliary battery terminal z4-5 (IL+2) and a negative (-) lead to terminal z4-8 (EAU) 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.
