1. INSPECT STEERING PAD SWITCH ASSEMBLY


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


    E210270E04


    Standard Resistance:

    Tester Connection
    		Condition
    		Specified Condition
    1 (HO) - Terminal-A
    		Always
    		Below 1 Ω
    4 (DIST) - 7 (ECC)
    		No switch pushed
    		95 to 105 kΩ
    Distance control switch pushed
    		Below 2.5 Ω
    2 (+DP) - 3 (-DP)
    		No switch pushed
    		95 to 105 kΩ
    DISP switch pushed
    		Below 2.5 Ω
    11 (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
    		2955 to 3265 Ω
    10 (AU2) - 8 (EAU)
    		No switch pushed
    		95 to 105 kΩ
    MODE switch pushed
    		Below 2.5 Ω
    Voice switch pushed*1
    		2955 to 3265 Ω
    On hook switch pushed*1
    		313 to 345 Ω
    Off hook switch pushed*1
    		950 to 1050 Ω

    1. *1: w/ Telephone Microphone Assembly

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

  1. Check the illumination


    E222754E04


    1. Disconnect the steering pad switch assembly connector.

    2. Check that the steering pad switch assembly illuminates according to the table below.

      OK:

      Connection
      		Specified Condition
      Auxiliary battery positive (+) → 5 (IL+2)
      Auxiliary battery negative (-) → 8 (EAU)
      		Switches of steering pad switch LH side illuminates
      Auxiliary battery positive (+) → 5 (IL+2)
      Auxiliary battery negative (-) → 3 (-DP)
      		Switches of steering pad switch RH side illuminates

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