STEERING PAD SWITCH INSPECTION


  1. INSPECT STEERING PAD SWITCH ASSEMBLY (for Radio Receiver Type)


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

      B000JJ5E01
      Standard Resistance
      Tester Connection Condition Specified Condition
      1 (HO) - Terminal-A Always Below 2.5 Ω
      11 (AU1) - 8 (EAU) No switch pushed 95 to 105 kΩ
      Up (LH) switch pushed Below 2.5 Ω
      Down (LH) 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
      3 (+DP2) - 8 (EAU) No switch pushed 95 to 105 kΩ
      Back switch pushed Below 2.5 Ω
      Up (RH) switch pushed 313 to 345 Ω
      Down (RH) switch pushed 950 to 1050 Ω
      Page switch pushed 2955 to 3265 Ω
      2 (+DP) - 8 (EAU) No switch pushed 95 to 105 kΩ
      Enter switch pushed Below 2.5 Ω

      Tech Tips

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

    2. Check the illumination.

      B000HU7E01

      1. Connect a positive (+) lead from the battery to terminal 5 (IL+2) and a negative (-) lead to terminal 8 (EAU) of the steering pad switch assembly connector.

      2. Check that the switch illumination illuminates.

        OK
        The steering pad switch illumination illuminates.
