STEERING PAD SWITCH INSPECTION

PROCEDURE


  1. INSPECT STEERING PAD SWITCH ASSEMBLY


    1. Inspect the steering pad switch assembly.


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

        *1 Seek+ Switch *2 Seek- Switch
        *3 Volume+ Switch *4 Volume- Switch
        *5 MODE Switch *6 Voice Switch
        *7 Off Hook Switch *8 On Hook Switch
        *9 Up Switch *10 Down Switch
        *11 Left Switch *12 Right Switch
        *13 Enter Switch *14 Top Switch
        *15 Back Switch *16 LDA Switch (LDA only)
        *17 ACC Switch (ACC only) *18 ACC Switch
        *19 LDA Switch - -

        		 - -
        Standard Resistance
        Tester Connection Switch Condition Specified Condition
        A11 (AU1) - A8 (EAU) No switch is pushed 95 to 105 kΩ
        Seek+ is pushed Below 2.5 Ω
        Seek- is pushed 313 to 345 Ω
        Volume+ is pushed 950 to 1050 Ω
        Volume- is pushed 2955 to 3265 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 313 to 345 Ω
        Off Hook switch is pushed 950 to 1050 Ω
        Voice switch is pushed 2955 to 3265 Ω
        A2 (+DP) - A8 (EAU) No switch is pushed 95 to 105 kΩ
        Enter switch is pushed Below 2.5 Ω
        Top switch is pushed 313 to 345 Ω
        Back switch is pushed 950 to 1050 Ω
        A3 (+DP2) - A8 (EAU) No switch is pushed 95 to 105 kΩ
        Left switch is pushed Below 2.5 Ω
        Up switch is pushed 313 to 345 Ω
        Down switch is pushed 950 to 1050 Ω
        Right switch is pushed 2955 to 3265 Ω
        A4 (DIST) - A7 (ECC) ACC switch is pushed Below 2.5 Ω
        LDA switch is pushed 228 to 252 Ω
        A1 (HO) - B1 (HO) Always Below 2.5 Ω
        A12 (SDN) - C2 (SDN) Always Below 2.5 Ω
        A6 (SUP) - C1 (SUP) Always Below 2.5 Ω
        A7 (ECC) - C3 (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.
