  1. DATA LIST

    Tech Tips

    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.

    Tech Tips

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


    1. Warm up the engine.

    2. Turn the A/C switch off.

    3. Turn the engine switch off.

    4. Connect the GTS to the DLC3.

    5. Turn the engine switch on (IG).

    6. Turn the GTS on.

    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.

    • To accurately confirm whether the vehicle was stopped or not, use "SPD (SP2)", which is the automatic transmission output speed.

    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.

    Tech Tips

    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.

    Knock Feedback Value Knocking feedback value Min.: -1024° CA,Max.: 1023.9° CA -

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

    Ignition timing = Most retarded timing value*1 + Knock Correct Learn Value*2 + Knock Feedback Value*3 + each compensation amountExample: 21° CA = 10° CA + 14° CA - 3° CA

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

    *2: The knock correction learned value is calculated as shown below in order to keep Knock Feedback Value as close to -3° CA as possible.

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

    When Knock Feedback Value is higher than -2° CA, Knock Correct Learn Value is slowly increased.

    *3: The base value is -3° 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° CA: There is no knocking and ignition timing is advanced.

    • -6° CA: Knocking is present and the ignition timing is being retarded.

    Tech Tips

    If Knock Feedback Value does not change around the time when knocking occurs even though knocking continues (for example, stays at -3° 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° CA,Max.: 1023.9° 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.

    Tech Tips

    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.).

    Misfire Margin Misfire monitoring Min.: -128%, Max.: 127% -128 to 127: Idling

    This is the misfire detection margin.

    Misfire Margin = (Misfire detection threshold - maximum engine speed variation) / misfire detection threshold x 100%

    When the variation in the engine speed is large and exceeds the misfire detection threshold, the misfire count starts. Misfire margin is a measure of how much the engine speed variation can increase with respect to the threshold before the engine is determined to be misfiring.

    A large value means there is a large margin for the engine speed to vary before the engine is determined to be misfiring.

    Example:

    When the engine is determined to be misfiring, Misfire Margin = -128 to 0%.

      Check the Cylinder Compression Check the cylinder compression pressure ON/OFF Fuel injection and ignition stop in all cylinders.

      Tech Tips

      In Check the Cylinder Compression 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 engine switch off.

      3. Connect the GTS to the DLC3.

      4. Turn the engine switch on (IG).

      5. Turn the GTS on.

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

        Tech Tips

        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.

        Tech Tips

        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.

        Tech Tips

        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.

        Tech Tips

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

      10. Monitor the engine speed (Engine Speed of Cyl #1 to #6) displayed on the GTS.

        Tech Tips

        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. Enter the following menus: Function / Snapshot Review / Engine and ECT / Snapshot File Manager. Then select the recorded data and display the data.

        Tech Tips

        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.

        Tech Tips

        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.

      • *3: Activate the VSV for Evap Control (Idling after warming up)

      A01A7MME26

      Tech Tips

      Even when the Active Test is turned on (the purge VSV is opened 30%), air fuel ratio feedback continues and control is performed so that the air fuel ratio is the stoichiometric ratio. Therefore, by observing the change in "Short FT", it is possible to determine whether the purge VSV is actually open as well as the concentration of HC in the purge gas.

      Tester Display Measurement Item/Range Normal Condition
      Activate the VSV for Evap Control - ▲A ▲B
      Active Test operation ON OFF
      EVAP (Purge) VSV 29.8% 0.0%
      Short FT #1 -9.375% 0.000%
      Injection (Port) 2127 μs 2190 μs
      AFS Voltage B1S1 3.356 V 3.234 V

      Tech Tips

      The graphs and values above are for reference only because the fuel injection volume (compensation volume) varies depending on the HC density of the purge air from the canister.

      B001TSBE22

      Tech Tips


      • Usually, Throttle Position Command (Target Value) and Throttle Position No. 1 (Actual Value) are almost the same.

      • If any DTCs related to the Electronic Throttle Control System (ETCS) are stored, this Active Test does not function.

      Tester Display Measurement Item/Range Normal Condition
      Control the ETCS Open/Close Fast Speed - ▲A ▲B
      Active Test operation Open Close
      Throttle Position Command 2.597 V 0.820 V

      Tester Display Measurement Item/Range Normal Condition
      Control the VVT Linear (Bank 1) - ▲A ▲B
      Active Test operation* 15% -15%
      VVT Change Angle #1 54.9 DegFR 0.0 DegFR
      VVT OCV Duty #1 66.8% 26.8%
      VVT Aim Angle #1 46.8% 46.8%

      Tech Tips


      • *: Change the control value for Control the VVT Linear to 15% or -15%.

      • The Control the VVT Linear Active Test considers the value of VVT Aim Angle to be 0 and raises or lowers the duty ratio with respect to VVT Aim Angle.

      • The sum of the control value for the Control the VVT Linear Active Test and the value of VVT Aim Angle is approximately equal to the value of VVT OCV Duty.

      • When the control value for the Control the VVT Linear Active Test is changed a few times, there should not be a large discrepancy between VVT OCV Duty when the system starts advancing or retarding the timing and the rate of change of VVT Change Angle.

  26. SYSTEM CHECK

    Tech Tips

    Performing a system check enables the system, which consists of multiple actuators, to be operated without removing any parts. In addition, it can show whether or not any DTCs are stored, and can detect potential malfunctions in the system. The system check can be performed with the Techstream.


    1. Connect the Techstream to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the Techstream on.

    4. Enter the following menus: Powertrain / Engine and ECT / Utility.
