The vehicle is equipped with an SRS (Supplemental Restraint System) which includes components such as airbags. Before servicing (including removal or installation of parts), be sure to read the PRECAUTION in the SRS Click here.


  1. INSPECT STEERING PAD SWITCH ASSEMBLY (w/ Dynamic Radar Cruise Control System)


    1. Disconnect the z35 switch connector.

      A01EO1DE05

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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      6 (AU1) - 8 (EAU) No switch is pushed 100 kΩ
      6 (AU1) - 8 (EAU) Seek+ switch pushed Below 2.5 Ω
      6 (AU1) - 8 (EAU) Seek- switch pushed 329 Ω
      6 (AU1) - 8 (EAU) Volume+ switch pushed 1000 Ω
      6 (AU1) - 8 (EAU) Volume- switch pushed 3110 Ω
      7 (AU2) - 8 (EAU) No switch is pushed 100 kΩ
      7 (AU2) - 8 (EAU) MODE switch pushed Below 2.5 Ω
      7 (AU2) - 8 (EAU) ON Hook switch pushed 329 Ω
      7 (AU2) - 8 (EAU) OFF Hook switch pushed 1000 Ω
      7 (AU2) - 8 (EAU) Voice switch pushed 3110 Ω
      9 (+DP) - 8 (EAU) DISP switch pushed Below 2.5 Ω
      10 (ECC) - 2 (DIST) ACC switch pushed Below 2.5 Ω

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

  2. INSPECT STEERING PAD SWITCH ASSEMBLY (w/o Dynamic Radar Cruise Control System)


    1. Disconnect the z35 switch connector.

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      6 (AU1) - 8 (EAU) No switch is pushed 100 kΩ
      6 (AU1) - 8 (EAU) Seek+ switch pushed Below 2.5 Ω
      6 (AU1) - 8 (EAU) Seek- switch pushed 329 Ω
      6 (AU1) - 8 (EAU) Volume+ switch pushed 1000 Ω
      6 (AU1) - 8 (EAU) Volume- switch pushed 3110 Ω
      7 (AU2) - 8 (EAU) No switch is pushed 100 kΩ
      7 (AU2) - 8 (EAU) MODE switch pushed Below 2.5 Ω
      7 (AU2) - 8 (EAU) On hook switch pushed 329 Ω
      7 (AU2) - 8 (EAU) Off hook switch pushed 1000 Ω
