SFI SYSTEM DATA LIST / ACTIVE TEST


  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. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the GTS on.

    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.

      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.

      *3: 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.

    Tech Tips

    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.: 1023.9 deg(CA) -

    • Stored as Freeze Frame Data: Yes

    • 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.).

  23. ACTIVE TEST

    Tech Tips

    Using the GTS to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.

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

      11. Start the engine.

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

        Note


        • If the Check the Cylinder Compression Active Test needs to be performed after it is turned ON and performed once, press the Exit button to return to the Active Test menu screen. Then perform the Check the Cylinder Compression Active Test again.

        Tech Tips


        • At first, the GTS display will show each cylinder's engine speed measurement to be extremely high. After the engine has started, each cylinder's engine speed measurement will change to the actual engine speed.

        • As soon as the measurements are obtained, finish the Active Test.

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

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

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

        Tech Tips

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

      16. Check the change in engine speed values.

        Tech Tips

        As the data values of the Active Test return to their default values when engine 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 engine running.

        A01KT8WE22

        Tech Tips

        During the Active Test, air fuel ratio feedback control and feedback learning are stopped.

        O2S B1S2 0.035 V 0.955 V

        Tech Tips


        • Usually, the value of AFS Voltage B1S1 drops below 3.1 V when the control value for Control the Injection Volume for A/F Sensor is changed to 12.5%.

        • Usually, the value of AFS Voltage B1S1 changes to 3.4 V or higher when the control value for Control the Injection Volume for A/F Sensor is changed to -12.5%.

        • Usually, the value of O2S B1S2 changes to 0.55 V or higher when the control value for Control the Injection Volume for A/F Sensor is changed to 12.5%.

        • Usually, the value of O2S B1S2 drops below 0.4 V when the control value for Control the Injection Volume for A/F Sensor is changed to -12.5%.

        Injector (Port) 2267.0 μs 2489.0 μs
        AFS Voltage B1S1 3.249 V 3.205 V

        Tech Tips


        • Even when the Active Test is performed (the purge VSV is opened 30%), the ECM performs air fuel ratio feedback to maintain the air fuel ratio at the stoichiometric ratio. Therefore, by observing the change in the Data List item "Injector (Port)", it is possible to determine whether the purge VSV is actually open.

        • 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.

      • *5: Control the VVT Linear (Bank 1)

        A01KTVTE31
        Tester Display Measurement Item Normal Condition

        VVT Change Angle #1 42.9 DegFR 0.0 DegFR
        VVT OCV Duty #1 67.0% 7.0%
        VVT Aim Angle #1 37.0% 37.0%

        Tech Tips


        • *: Change the control value for Control the VVT Linear to 30% or -30%.

        • The Control the VVT Linear Active Test considers the value of VVT Aim Angle #1 to be 0 and raises or lowers the duty ratio with respect to VVT Aim Angle #1.

        • The sum of the control value for the Control the VVT Linear Active Test and the value of VVT Aim Angle #1 is approximately equal to the value of VVT OCV Duty #1.

        • 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 #1 when the system starts advancing or retarding the timing and the rate of change of VVT Change Angle #1.

        • Test not possible with the shift lever in P during charge control. Move the shift lever to N to perform test.

      • *6: Control the EGR Step Position (Idling after warming up, A/C off)

        A01KTKFE06
        *1 EGR Step Position [step]
        *2 Engine Speed [rpm]
        *3 MAP [kPa]
        Tester Display Measurement Item Normal Condition
        Control the EGR Step Position - ▲A ▲B ▲C ▲D
        EGR Step Position 0 step 10 step 20 step 30 step
        MAP 29 kPa(abs) [218 mmHg(abs)] 31 kPa(abs) [233 mmHg(abs)] 59 kPa(abs) [443 mmHg(abs)] 74 kPa(abs) [555 mmHg(abs)]

        Tech Tips


        • When the value of Control the EGR Step Position is "0step", the value of MAP should be between 20 and 40kPa (150 to 300 mmHg).

        • When the EGR system is normal and the value of Control the EGR Step Position is changed from "0 step" to "30 step", the value of MAP will increase to a value at least 10 kPa (75 mmHg) higher than the value of MAP when the value of Control the EGR Step Position was "0 step".

        • This data is taken from an Active Test in which the step position was raised in increments of 1 step. The EGR valve inspection in the troubleshooting procedures checks the operation of the valve by stalling the engine and raises the step position in increments of 5 step.

        • Do not leave the EGR valve open for 10 seconds or more during the Active Test.

        • Be sure to return the EGR valve to step 0 when the Active Test is completed.

        • Do not open the EGR valve 30 steps or more during the Active Test.
