    READ VALUE USING GTS (COOLANT TEMPERATURE)


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine / Data List.

    5. Read the Data List according to the display on the GTS.


      1. Powertrain > Engine > Data List
        Tester Display Measurement Item Range Normal Condition Diagnostic Note
        Coolant Temperature Engine coolant temperature Min.: -40°C (-40°F), Max.: 140°C (284°F) 75 to 100°C (167 to 212°F): After warming up

        This is the engine coolant temperature.

        Tip:

        • After warming up the engine, the engine coolant temperature will be 75 to 100°C (167 to 212°F).

        • After a long soak, the engine coolant temperature, intake air temperature and ambient air temperature will be approximately equal.

        • If the value is -40°C (-40°F), or higher than 135°C (275°F), the sensor circuit is open or shorted.

        • Check if the engine overheats if the value indicated is higher than 135°C (275°F).
