STEERING PAD SWITCH INSPECTION

PROCEDURE


  1. INSPECT STEERING PAD SWITCH ASSEMBLY


    1. Inspect the pad switch.


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

        A01CWMPC02
        *A w/ Shift Paddle Switch - -
        *1 Volume+ Switch *2 Volume- Switch
        *3 Left Switch *4 Right Switch
        *5 Up Switch *6 Down Switch
        *7 ENTER Switch *8 MODE Switch
        *9 Back Switch *10 w/ Voice Switch
        *11 Off Hook Switch *12 On Hook Switch
        *13 DISP Switch - -
        *a

        Component without harness connected

        		 - -
        Standard Resistance
        Tester Connection Switch Condition Specified Condition
        A11 (AU1) - A8 (EAU) No switch is pushed 95 to 105 kΩ
        Volume+ is pushed 950 to 1050 Ω
        Volume- is pushed 2954 to 3265 Ω
        Up switch is pushed Below 2.5 Ω
        Down switch is pushed 312 to 345 Ω
        A9 (AU3) - A8 (EAU) No switch is pushed 95 to 105 kΩ
        Left switch is pushed 2954 to 3265 Ω
        Right switch is pushed 950 to 1050 Ω
        ENTER Switch is pushed Below 2.5 Ω
        Back Switch is pushed 312 to 345 Ω
        A10 (AU2) - A8 (EAU) No switch is pushed 95 to 105 kΩ
        MODE switch is pushed Below 2.5 Ω
        On Hook switch is pushed 312 to 345 Ω
        Off Hook switch is pushed 950 to 1050 Ω
        Voice switch is pushed 2954 to 3265 Ω
        A2 (+DP) - A3 (-DP) DISP switch is pushed Below 2.5 Ω
        A1 (HO) - B (HO) Always Below 2.5 Ω
        A6 (SUP) - C2 (SUP) Always Below 2.5 Ω
        A12 (SDN) - C3 (SDN) Always Below 2.5 Ω
        A7 (ECC) - C7 (ECC) Always Below 2.5 Ω

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

      2. Connect the battery positive (+) lead to terminal A5 (IL+2) and the negative (-) lead to terminal A8 (EAU) of the steering pad switch assembly connector.

      3. 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 the pad switch.
