    2. Check the illumination.

      A01EUSQE01

      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.
