        ASL switch is pushed Below 2.5 Ω
        1 (HO) - HO Always Below 1 Ω

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

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

    5. Check that the switch illumination comes on.

      OK
      Steering pad switch illumination comes on.

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