STEERING PAD SWITCH INSPECTION


  1. INSPECT STEERING PAD SWITCH LH


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

      A00439JE04
      Standard Resistance
      Tester Connection Condition Specified Condition
      1 (IL+2) - 2 (IL+2) No switch pushed Below 1 Ω
      3 (AU1) - 5 (EAU) No switch pushed 95 to 105 kΩ
      Seek+ switch pushed Below 2.5 Ω
      Seek- switch pushed 323 to 335 Ω
      Volume+ switch pushed 980 to 1020 Ω
      Volume- switch pushed 3048 to 3172 Ω
      4 (AU2) - 5 (EAU) No switch pushed 95 to 105 kΩ
      MODE switch pushed Below 2.5 Ω
      On hook switch pushed 323 to 335 Ω
      Off hook switch pushed 980 to 1020 Ω
      Voice switch pushed*1 3048 to 3172 Ω

      1. Connect an auxiliary battery positive (+) lead to terminal IL+2 and a negative (-) lead to terminal EAU of the steering pad switch LH connector.

      2. Check that the switch illumination comes on.

        OK
        Steering pad switch illumination comes on.
