    1. Inspect the pad switch.


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

        Standard Resistance
        Tester Connection Switch Condition Specified Condition
        A11 (AU1) - A3 (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 2955 to 3265 Ω
        A5 (AU2) - A3 (EAU) No switch pushed 95 to 105 kΩ
        MODE switch pushed Below 2.5 Ω
        Return switch pushed 313 to 345 Ω
        On hook switch pushed 313 to 345 Ω
        Off hook switch pushed 950 to 1050 Ω
        Voice switch pushed 2955 to 3265 Ω
        A10 (SUP) - B1 (SUP) Always Below 1 Ω
        A4 (SDN) - B2 (SDN) Always Below 1 Ω
        A7 (ECC) - B3 (ECC) Always Below 1 Ω

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