STEERING PAD SWITCH INSPECTION

  1. INSPECT STEERING PAD SWITCH LH (for Audio and Visual System (for Radio Receiver Type))

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

      A011WN5E05
      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      1 (HO) - Terminal-A Always Below 1 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/HOLD switch pushed Below 2.5 Ω

      Tech Tips

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

    2. Check the illumination.

      A011WRME04

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

      2. Check that the switch illumination comes on.

        OK
        Steering pad switch illumination comes on.
