      *1 Seek+ Switch *2 Seek- Switch
      *3 Volume+ Switch *4 Volume- Switch
      *5 MODE Switch *6 Off Hook Switch
      *7 w/ Voice Switch *8 On Hook Switch
      *9 Menu Switch *10 ENTER Switch
      *11 UP/DOWN Up Switch *12 UP/DOWN Down Switch
      *13 w/ Wide View Front and Side Monitor Switch *14 w/ Distance Control Switch

      1. Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Specified Condition
        10 (AU1) - 8 (EAU) No switch pushed 95 to 105 kΩ
        Seek+ switch pushed Below 2.5 Ω
        Seek- switch pushed 313 to 345 Ω
        Volume+ switch pushed 950 to 1050 Ω
        Volume- switch pushed 2950 to 3265 Ω
        9 (AU2) - 8 (EAU) No switch pushed 95 to 105 kΩ
        MODE switch pushed Below 2.5 Ω
        On hook switch pushed 313 to 345 Ω
        Off hook switch pushed 950 to 1050 Ω
        Voice switch pushed *7 2950 to 3265 Ω
        2 (DISP) - 3 (GND1) No switch pushed 95 to 105 kΩ
        Menu switch pushed Below 2.5 Ω
        ENTER switch pushed 313 to 345 Ω
        UP/DOWN Up switch pushed 2950 to 3265 Ω
        UP/DOWN Down switch pushed 950 to 1050 Ω
        7 (+DP) - 3 (GND1) Wide View Front and Side Monitor switch pushed *13 Below 2.5 Ω
        4 (DIST) - 6 (ECC) Distance Control switch pushed *14 Below 2.5 Ω

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

    2. Check the illumination.


      1. Connect the battery positive (+) lead to terminals IL+2 and the negative (-) lead to terminals EAU and GND1 of the steering pad switch assembly connector.

      2. 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.

  2. INSPECT STEERING PAD SWITCH ASSEMBLY (w/ Audio + Tel)


    1. Inspect the pad switch.

        Volume- switch pushed 2950 to 3265 Ω
        9 (AU2) - 8 (EAU) No switch pushed 95 to 105 kΩ
        MODE switch pushed Below 2.5 Ω
        On hook switch pushed 313 to 345 Ω
        Off hook switch pushed 950 to 1050 Ω

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

    2. Check the illumination.


      1. Connect the battery positive (+) lead to terminals IL+2 and the negative (-) lead to terminals EAU and GND1 of the steering pad switch assembly connector.

      2. 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.

  3. INSPECT STEERING PAD SWITCH RH
