  1. DATA LIST

    Tip:

    Using the GTS to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.

    Note:

    • In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

    • The actual values may differ from the values listed in the chart under "Results of real-vehicle check" due to climate, weather conditions, etc.

    Tip:

    Normal Condition: If no conditions are specifically stated for "idling", the shift lever should be in N, the A/C switch should be off and all accessory switches should be off.

  2. Various Vehicle Conditions 1 (All Data)


    1. Powertrain > Engine > Data List
      Tester Display Measurement Item Range Normal Condition Diagnostic Note
      Vehicle Speed Vehicle speed Min.: 0 km/h (0 mph), Max.: 255 km/h (158 mph) Actual vehicle speed

      • This is the current vehicle speed.

      • The vehicle speed is detected using the wheel speed sensors.


        • Vehicle speed data is delayed when it is displayed. Therefore, even if the vehicle speed listed in the freeze frame data is 0 km/h (0 mph), this does not always mean that the malfunction occurred when the vehicle was stopped.
      Engine Speed Engine speed Min.: 0 rpm, Max.: 16383 rpm 650 to 750 rpm: Idling When the crankshaft position sensor is malfunctioning, "Engine Speed" is approximately 0 rpm or varies greatly from the actual engine speed.
      Calculate Load Load calculated by ECM Min.: 0%, Max.: 100% -

      • This is the engine load calculated based on the estimated intake manifold pressure.

      • Calculate Load = Estimated intake manifold pressure / maximum intake manifold pressure x 100 (%)

        (For example, when the estimated intake pressure is the same as atmospheric pressure, Calculate Load is 100%).
      Vehicle Load Vehicle load Min.: 0%, Max.: 25700% -

      • This is the engine intake air charging efficiency.

      • Vehicle Load = Current intake airflow (g/rev.) / maximum intake airflow

        Maximum intake airflow = Displacement (L) / 2 x 1.2 (g/rev.)

      Tip:

      Due to individual engine differences, intake air temperature, etc., the value may exceed 100%.

      Intake airflow (g/rev.) = Intake airflow (gm/sec) x 60 / Engine speed (rpm)

      (Intake airflow (gm/sec) is MAF)
      MAF Airflow rate from mass air flow meter sub-assembly Min.: 0 gm/sec, Max.: 655.35 gm/sec

      • 1.0 to 5.0 gm/sec: Idling

      • 5.0 to 9.0 gm/sec: 2000 rpm

      • 9.0 to 15.0 gm/sec: 3000 rpm

      		 This is the intake air amount from the mass air flow meter sub-assembly.
      Atmosphere Pressure Atmospheric pressure Min.: 0 kPa (0 mmHg), Max.: 255 kPa (1912 mmHg) Equivalent to atmospheric pressure (absolute pressure)

      • This value is calculated from the intake air amount.

      • Standard atmospheric pressure: 101 kPa(abs) [760 mmHg(abs)]

      • For every 100 m (328 ft.) increase in altitude, pressure drops by 1 kPa (7.5 mmHg). This varies by weather.
      Coolant Temp Coolant temperature Min.: -40°C (-40°F), Max.: 140°C (284°F) 80 to 95°C (176 to 203°F): After warming up

      This is the engine coolant temperature.

      Tip:

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

      • After a long soak, the engine coolant temperature, intake air temperature and ambient air temperature are 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 when the value indicates higher than 135°C (275°F).
      Intake Air Intake air temperature Min.: -40°C (-40°F), Max.: 140°C (284°F) Equivalent to temperature at location of mass air flow meter sub-assembly

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

      • If the value is -40°C (-40°F), or higher than 128°C (262°F), the sensor circuit is open or shorted.
      Engine Run Time Engine run time Min.: 0 s, Max.: 65535 s Time after engine start

      ST1 Brake pedal signal ON or OFF

      • ON: Brake pedal depressed

      • OFF: Brake pedal fully released

      		 This is the stop light switch assembly signal (ST1- terminal).
      System Guard System guard ON or OFF ON

      • When there is a difference between the target and actual throttle valve opening angles, system guard turns off and stops the electronic throttle control system function.

      • OFF: Electronic throttle control is stopped.
      Open Side Malfunction Open malfunction ON or OFF OFF This parameter indicates a malfunction in the electronic throttle when the throttle valve is open.
      Throttle Idle Position Whether or not throttle position sensor detecting idle ON or OFF -

      • This is a parameter calculated by the ECM.

      • The value is ON when the throttle is at the idle position and OFF when the throttle is open.
      Throttle Require Position Required throttle position Min.: 0 V, Max.: 4.98 V - This is a value calculated by the ECM showing the voltage for the target throttle valve position. It is almost an exact match of the Throttle Position No. 1 value except during very rapid throttle valve movement, such as that used during wheel spin control.
      Throttle Sensor Position Throttle sensor position Min.: 0%, Max.: 100%

      • 0%: Accelerator pedal fully released

      • 50 to 80%: Accelerator pedal fully depressed

      • This is the throttle valve opening amount used for engine control.

        (100% signifies 125° of throttle valve rotation. This does not include the amount the throttle valve is opened to maintain the idle speed during idling.)

      • This value has no meaning when the ignition switch is turned to ON and the engine is stopped.

      • The throttle valve opening amount during idling is indicated by 0%. When the throttle valve is fully open, the value is 68%.
      Throttle Position No.1 Throttle position sensor No. 1 output voltage Min.: 0 V, Max.: 4.98 V

      Almost same as "Throttle Require Position"


      • 0.5 to 1.1 V: Accelerator pedal fully released

      • 3.2 to 4.8 V: Accelerator pedal fully depressed

      Throttle Position No.2 Throttle position sensor No. 2 output voltage Min.: 0 V, Max.: 4.98 V

      • 2.1 to 3.1 V: Accelerator pedal fully released

      • 4.6 to 4.98 V: Accelerator pedal fully depressed

      • 2.1 to 3.1 V: Fail-safe operating

      		 This is the throttle position sensor No. 2 output voltage.
      Throttle Position Command Throttle position command value Min.: 0 V, Max.: 4.98 V - Throttle Position Command is the same value as Throttle Require Position.
      Throttle Sens Open Pos #1 Throttle position sensor No. 1 Min.: 0 V, Max.: 4.98 V 0.6 to 1.4 V This is the throttle position sensor No. 1 output voltage when there is no current supplied to the electronic throttle actuator. The accelerator pedal is released but the throttle valve is kept open by the throttle valve opener with the Ignition switch ON.
      Throttle Sens Open Pos #2 Throttle position sensor No. 2 Min.: 0 V, Max.: 4.98 V 1.7 to 2.5 V This is the throttle position sensor No. 2 output voltage when there is no current supplied to the electronic throttle actuator. The accelerator pedal is released but the throttle valve is kept open by the throttle valve opener with the Ignition switch ON.
      Throttle Motor Current Throttle actuator current Min.: 0 A, Max.: 19.9 A 0 to 3.0 A: Idling

      • When this value is large but the actual opening angle (Throttle Position No. 1) does not reach the target opening angle (Throttle Require Position), there is an "unable to open" malfunction.

      • This value normally fluctuates around 1 A.
      Throttle Motor DUTY Throttle actuator Min.: 0%, Max.: 100% 10 to 22%: Idling This is the output duty ratio of the throttle actuator drive circuit.
      Throttle Motor Duty (Open) Throttle actuator duty ratio (open) Min.: 0%, Max.: 255% 0 to 40%: Idling

      • This is the duty ratio used to drive the throttle actuator and open the throttle valve. It is an ECM command signal.

      Throttle Motor Duty (Close) Throttle actuator duty ratio (close) Min.: 0%, Max.: 255% 0 to 40%: Idling

      This is the duty ratio used to drive the throttle actuator and close the throttle valve. It is an ECM command signal.

      Tip:

      During idling, the throttle valve opening angle is usually controlled using a duty ratio drive signal which closes the throttle valve. However, when carbon deposits build up, it may be necessary to open the throttle valve more than the throttle valve opener does. In that case, the opening angle is controlled using a "Throttle Motor Duty (Open)" signal which opens the throttle valve.
      Throttle Fully Close Learn Throttle valve fully closed position (learned value) Min.: 0 V, Max.: 4.98 V 0.4 to 1.0 V: Accelerator pedal fully released

      • The ECM uses this learned value to determine the fully closed (and fully open) position of the throttle valve. This learned value is calculated by the ECM with the throttle valve opener angle (approximately 4 to 7°, the position when the ignition switch is turned to ON, the accelerator pedal is released and the throttle actuator is off).

      • Learning is performed immediately after the ignition switch is turned to ON.
      +BM Voltage +BM voltage Min.: 0 V, Max.: 79.998 V 11 to 14 V: Ignition switch ON and system normal This is the power supply for the electronic throttle actuator. When the power supply is interrupted for approximately 1 second, DTCs P2118 (open circuit) and P0657 (short circuit, ECU malfunction) are stored and the electronic throttle control system enters fail-safe mode (normal operation is not restored until the ignition switch is turned off).
      Actuator Power Supply Actuator power supply ON or OFF ON: Idling If +BM power is lost, this item changes to OFF.

      ISC Feedback Value ISC feedback amount Min.: -40 L/s, Max.: 39.99 L/s -

      This is the feedback amount necessary to adjust the airflow amount to maintain the target idle speed.

      Tip:

      When the idle speed differs from the target, the feedback amount is adjusted. If the feedback amount becomes more than a certain value, this will be reflected in the ISC learned airflow value.
      ISC Learning Value ISC learned airflow value Min.: -40 L/s, Max.: 39.99 L/s -

      This is the learned value of the airflow amount necessary for engine idling.

      Tip:

      • If ISC Feedback Value becomes more than a certain value, this will be reflected in ISC Learning Value.

      • ISC Flow (total ISC airflow amount) = ISC Learning Value + ISC Feedback Value + each compensation amount

      Low Revolution Control Low engine speed control operation state ON or OFF -

      • This parameter indicates whether the engine speed dropped immediately after starting due to poor combustion, etc. This parameter changes to ON when the engine speed drops to below the following speeds 1 to 7 seconds after the engine is started (when the A/C is on, the engine speed thresholds below increase by 100 to 200 rpm).


        • 900 rpm (when the engine coolant temperature is 10°C (50°F)).

        • 850 rpm (when the engine coolant temperature is 30°C (86°F)).

        • 750 rpm (when the engine coolant temperature is 60°C (140°F)).

          Before 5 seconds elapse after starting the engine, this parameter indicates the status of the previous trip.

          After 5 seconds elapse after starting the engine, this parameter indicates the status of the current trip.

          Tip:

          The engine is considered to have started when the engine speed reaches 400 rpm. When the engine speed decreases immediately after starting the engine, this parameter changes to ON and remains ON for the rest of the trip.

          ON: The engine speed decreased immediately after starting the engine.

          OFF: The engine speed did not decrease immediately after starting the engine.

      • For use when engine stall, starting problems or rough idle is present.

      Purge Density Learn Value Purge density learned value Min.: -200, Max.: 199.993 -

      • Purge Density Learn Value is the proportion of the decrease in injection volume (based on the change in the air fuel ratio feedback compensation value) related to a 1% purge flow rate.

      • When Purge Density Learn Value is a large negative value, the purge effect is large.

      • The purge density is determined from the change in the air fuel ratio feedback compensation value when purge flow is introduced.

      • Purge density learning is performed so that the feedback compensation value is 0 +/-2%.

      Tip:

      • Usually, the value is approximately +/-1%.

      • 1%: The concentration of HC in the purge gas is relatively low.

      • 0%: The concentration of HC in the purge gas is approximately equal to the stoichiometric air fuel ratio.

      • Large negative values indicate that the concentration of HC in the purge gas is relatively high.

      IGN Advance Ignition timing advance for No. 1 cylinder Min.: -64 deg, Max.: 63.5 deg BTDC 0 to 20 deg: Idling -
      Knock Feedback Value Knocking feedback value Min.: -1024 deg(CA), Max.: 1023.9 deg(CA) -

      • This is the ignition timing retard compensation amount determined by the presence or absence of knocking.

        Ignition timing = Most retarded timing value* + Knock Correct Learn Value* + Knock Feedback Value* + each compensation amount

        Example: 21 deg(CA) = 10 deg(CA) + 14 deg(CA) - 3 deg(CA)

        Most retarded timing value*: The most retarded timing value is a constant determined by the engine speed and engine load.

        Knock Correct Learn Value*: The knock correction learned value is calculated as shown below in order to keep Knock Feedback Value as close to -3 deg(CA) as possible.

        When Knock Feedback Value is less than -4 deg(CA), Knock Correct Learn Value is slowly decreased.

        When Knock Feedback Value is more than -2 deg(CA), Knock Correct Learn Value is slowly increased.

        Knock Feedback Value*: The base value is -3 deg(CA) and is adjusted based on the presence or absence of knocking. When there is no knocking, the value is increased, and when knocking is present, the value is decreased.

        -1 deg(CA): There is no knocking and ignition timing is advanced.

        -6 deg(CA): Knocking is present and the ignition timing is being retarded.

      Tip:

      If Knock Feedback Value does not change around the time when knocking occurs even though knocking continues (for example, stays at -3 deg(CA)), it can be determined that knocking is not being detected.


      • Possible Causes:

      • There is a problem with the knock control sensor sensitivity.

      • The knock control sensor is improperly installed.

      • There is a problem with a wire harness.
      Knock Correct Learn Value Knocking correction learned value Min.: -1024 deg(CA), Max.: 1023.9deg (CA) -

      • Refer to "Knock Feedback Value".

      • When there is knocking or a lack of power, compare the following values to another vehicle of the same model.


        • Engine Speed

        • Calculate Load

        • IGN Advance

        • Knock Feedback Value

        • Knock Correct Learn Value

      • Knock Correct Learn Value is large: There is no knocking and the ignition timing is advanced.

      • Knock Correct Learn Value is small: Knocking is present and the ignition timing is being retarded.

      Tip:

      When knocking continues even though Knock Correct Learn Value is less than that of the vehicle being used for comparison (in other words, the ignition timing is being retarded but the knocking is not stopping), there may be a buildup of deposits or other such problems due to deterioration over time (oil entering the cylinders, poor quality fuel, etc.).

        *1



















      Tip:

      *1:

      In this Active Test, the fuel and ignition of all cylinders is cut. The engine must then be cranked for approximately 10 seconds. At this time, the speed of each cylinder is measured. If the speed of one cylinder is more than the other cylinders, it can be determined that the compression pressure of that cylinder is lower than the other cylinders.


      1. Warm up the engine.

      2. Turn the ignition switch off.

      3. Connect the GTS to the DLC3.

      4. Turn the ignition switch to ON.

      5. Turn the GTS on.

      6. Enter the following menus: Powertrain / Engine and ECT / Active Test / Check the Cylinder Compression.

        Tip:

        To display the entire Data List, press the pull down menu button next to Primary. Then select Compression.

      7. Push the snapshot button to turn the snapshot function on.

        Tip:

        Using the snapshot function, data can be recorded during the Active Test.

      8. While the engine is not running, press the RIGHT or LEFT button to change Check the Cylinder Compression to ON.

        Tip:

        After performing the above procedure, Check the Cylinder Compression will start. Fuel injection for all cylinders is prohibited and each cylinder engine speed measurement enters standby mode.

      9. Crank the engine for about 10 seconds.

        Tip:

        Continue to crank the engine until the values change from the default value (51199 rpm).

      10. B0027F6

        Monitor the engine speed (Engine Speed of Cyl #1 to #4) displayed on the GTS.

        Tip:

        At first, the GTS displays extremely high cylinder engine speed values. After approximately 10 seconds of engine cranking, each cylinder engine speed measurement will change to the actual engine speed.

        Note:

        • Do not crank the engine continuously for 20 seconds or more.

        • If it is necessary to crank the engine again after Check the Cylinder Compression has been changed to ON and the engine has been cranked once, press Exit to return to the Active Test menu screen. Then change Check the Cylinder Compression to ON and crank the engine.

        • Use a fully-charged battery.

      11. Stop cranking the engine, and then change "Check the Cylinder Compression" to OFF after the engine stops.

        Note:

        If the Active Test is changed to OFF while the engine is being cranked, the engine will start.

      12. Push the snapshot button to turn the snapshot function off.

      13. Select "Stored Data" on the GTS screen, select the recorded data and display the data as a graph.

        Tip:

        If the data is not displayed as a graph, the change of the values cannot be observed.

      14. Check the change in engine speed values.

        Tip:

        As the data values of the Active Test return to their default values when cranking is stopped, the engine speed value of each cylinder cannot be observed. Therefore, it is necessary to use the data recorded with the snapshot function to check the engine speed values recorded during cranking.
