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

      Tech Tips

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

      Standard Voltage
      Tester Connection(Positive (+) tester probe - Negative (-) tester probe) Condition Specified Condition
      1 (IG) - 5 (IN) Always Below 1.25 V
      4 (+) - 5 (IN) Steering heater switch is pushed Below 1.25 V

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 (IG) - 4 (+) Steering heater switch is pushed Below 1 Ω
      Steering heater switch is not pushed 10 kΩ or higher
