      Standard Resistance
      Tester Connection Condition Specified Condition
      z9-6 (AU1) - z9-5 (AU-GND) No switch pushed 98 to 102 kΩ
      VOL+ switch pushed Below 2.5 Ω
      VOL- switch pushed 322 to 336 Ω
      SEEK+ switch pushed 980 to 1020 Ω
      SEEK- switch pushed 3048 to 3172 Ω
      z9-2 (DP) - z9-4 (EAU) No switch pushed 98 to 102 kΩ
      LEFT switch pushed Below 2.5 Ω
      UP switch pushed 322 to 336 Ω
      DOWN switch pushed 980 to 1020 Ω
      RIGHT switch pushed 3048 to 3172 Ω
      z9-1 (AU2) - z9-5 (AUGND) No switch pushed 98 to 102 kΩ
      MODE switch pushed Below 2.5 Ω
      z9-3 (DP2) - z9-4 (EAU) No switch pushed 98 to 102 kΩ
      ENTER switch pushed Below 2.5 Ω
      BACK switch pushed 980 to 1020 Ω
      z9-12 (HO) - A-1 (HO) Always Below 2.5 Ω
      z9-10 (ECC) - B-1 (ECC)* Always Below 2.5 Ω
      z9-11 (ECC) - B-3 (ECC)* Always Below 2.5 Ω

      *: w/ Cruise Control System

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

    2. Check the illumination.


      1. Connect a positive (+) lead from the battery to the terminal z9-8 (ILL+) and a negative (-) lead to the terminal z9-9 (ILL-) of the steering pad switch assembly connector.

      2. Check that the switch illumination illuminates.

        OK
        The steering pad switch illumination illuminates.

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