STEERING HEATER SWITCH INSPECTION

PROCEDURE


  1. INSPECT STEERING HEATER SWITCH


    1. B001H6GC01
      *a

      Component without harness connected

      (Steering Heater Switch)

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

      Standard Voltage
      Tester Connection (Positive (+) Tester Probe - Negative (-) Tester Probe) Switch Condition Specified Condition
      5 (IG) - 4 (INDC) Always Below 1.25 V
      2 (RC) - 4 (INDC) Steering heater switch is pushed Below 1.25 V

      Tech Tips

      As the circuit has a diode, perform the measurement in diode test mode, and do not mistake the polarity.

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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      5 (IG) - 2 (RC) Pressed Below 1 Ω
      Not pressed 10 kΩ or higher

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

    3. Check the illumination.


      1. Apply battery voltage between the terminals of the switch, and check the illumination condition of the steering heater switch.

        Standard Resistance
        Measurement Condition Specified Condition
        Battery positive (+) → A6 (ILL+) Battery negative (-) → A1 (E) Illuminates
