      Tip:

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

    2. A0009AXE14

      Check the illumination.

      Table 2. Text in Illustration
      *a

      Component without harness connected

      (Steering Pad Switch Assembly)

      		 - -

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

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