    INSPECT STEERING PAD SWITCH ASSEMBLY


    1. A0004FCE02

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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      z5-1 (HO) - Terminal A Always Below 2.5 Ω
      z5-4 (DIST) - z5-7 (ECC) Distance control switch pushed Below 2.5 Ω
      z5-4 (DIST) - z5-7 (ECC) Lane departure alert main switch being pushed and held 228 to 252 Ω
      z5-4 (DIST) - z5-7 (ECC) No switch pushed 10 kΩ or higher
      z5-10 (AU2) - z5-8 (EAU) No switch pushed 95 to 105 kΩ
      z5-10 (AU2) - z5-8 (EAU) MODE switch pushed Below 2.5 Ω
      z5-10 (AU2) - z5-8 (EAU) Voice switch pushed 2955 to 3265 Ω
      z5-10 (AU2) - z5-8 (EAU) Voice return switch pushed 313 to 345 Ω
      z5-10 (AU2) - z5-8 (EAU) On Hook switch pushed 313 to 345 Ω
      z5-10 (AU2) - z5-8 (EAU) Off Hook switch pushed 950 to 1050 Ω
      z5-11 (AU1) - z5-8 (EAU) No switch pushed 95 to 105 kΩ
      z5-11 (AU1) - z5-8 (EAU) Seek+ switch pushed Below 2.5 Ω
      z5-11 (AU1) - z5-8 (EAU) Seek- switch pushed 313 to 345 Ω
      z5-11 (AU1) - z5-8 (EAU) Volume+ switch pushed 950 to 1050 Ω
      z5-11 (AU1) - z5-8 (EAU) Volume- switch pushed 2955 to 3265 Ω
      A-3 (ECC) - z5-7 (ECC) Always Below 2.5 Ω

      Check the illumination.


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

      2. Check that the switch illumination comes on.

        OK
        Steering pad switch illumination comes on.
        Tip:

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