    2. Check the illumination.

      A01I3G0E01

      1. Connect a battery positive (+) lead to terminal 5 (IL+2) and a negative (-) lead to terminal 8 (EAU) of the steering pad switch assembly connector.

      2. Check that the switch illumination comes on.

        OK
        Steering pad switch illumination comes on.

        Tech Tips

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