COOLING FAN SYSTEM INSPECTION


  1. INSPECT COOLING FAN RELAY


    1. A01BGLPE01

      Check the resistance.


      1. Using an ohmmeter, measure the resistance between the terminals.

        Standard resistance
        Tester Connection Specified Condition
        3 - 5 10 kΩ or higher
        3 - 5 Below 1 Ω (when battery voltage is applied between terminals 1 and 2)

        If the result is not as specified, replace the relay.

  2. INSPECT COOLING FAN MOTOR


    1. Check that the motor turns smoothly when the battery is connected to the fan motor connector.

    2. Using an ammeter, measure the current while the motor is turning.

      Standard
      17 to 23 A (20°C (68°F)) at 12 V

  3. ENGINE COOLANT TEMPERATURE SENSOR


    1. Partially soak the sensor in the water and warm up the water.

      A01BFSCE01

    2. Measure the resistance between the terminals.

      Standard resistance
      Condition Specified Condition
      Approx. 20°C (68°F) 2.32 to 2.59 kΩ
      Approx. 80°C (176°F) 0.310 to 0.326 kΩ

      If the result is not as specified, replace the sensor.

      Note

      When checking the sensor in the water, keep the terminals dry. After the check, wipe the sensor dry.
