Data List / Active Test [10/2019 - 08/2020]

  1. DATA LIST 

    HINT: 

    Using the Techstream 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.

    HINT: 

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

    Ignition Timing Cylinder #1 Ignition timing advance for No. 1 cylinder Min.: -64 deg, Max.: 63.5 deg -15 to 31 deg: Idling (engine warmed up, A/C off and shift lever in N) -
    Knock F/B Value Knocking feedback value Min.: -1024 deg(CA), Max.: 1023.9 deg(CA) -17 to 0 deg(CA): Driving at 70 km/h (43 mph) 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 F/B Value*3 + each compensation amount
    Example: 21 deg(CA) = 10 deg(CA) + 14 deg(CA) - 3 deg(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 F/B Value as close to -3 deg(CA) as possible.
    When Knock F/B Value is less than -4 deg(CA), Knock Correct Learn Value is slowly decreased.
    When Knock F/B Value is higher 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.
    HINT: 
    If Knock F/B 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) -
    • Refer to "Knock F/B Value".

      • Engine Speed
      • Calculate Load
      • Ignition Timing Cylinder #1
      • Knock F/B 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.
    HINT: 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 does not stop), there may be a buildup of deposits or other such problems due to deterioration over time (oil entering the cylinders, poor quality fuel, etc.).

        2. Turn the ignition switch to ON.
        3. Enter the Control the Select Cylinder Fuel Cut.
        4. Select the cylinder for fuel cut (No. 1 to No. 4 cylinder) and turn the Active Test ON.
        5. Start the engine.

      HINT: 

      *3:

      While performing this Active Test, the fuel injection 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 Techstream to the DLC3.
      4. Turn the ignition switch to ON.
      5. Turn the Techstream on.
      6. Enter the following menus: Powertrain / Engine / Active Test / Check the Cylinder Compression.

        HINT: 

        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.

        HINT: 

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

      8. While the engine is not running, press the button to change Check the Cylinder Compression to "Start".

        HINT: 

        After performing the above procedure, the Active Test will start. Fuel injection for all cylinders is prohibited and engine speed measurement enters standby mode.

      9. Crank the engine for about 10 seconds.

        HINT: 

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

      10. Monitor the engine speed (Engine Speed Cylinder #1 to #4) displayed on the Techstream.
        NOTE:
        • In order to protect the starter assembly, 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 "Start" and the engine has been cranked once, press Exit to return to the Active Test menu screen. Then change Check the Cylinder Compression to "Start" and crank the engine.
        • Make sure the battery is fully charged before performing this Active Test.

        HINT: 

        • At first, the Techstream will display extremely high cylinder engine speed values. After approximately 10 seconds of engine cranking, the engine speed measurement of each cylinder will change to the actual engine speed.
        • If the cylinder engine speed values (Engine Speed Cylinder #1 to #4) displayed in the Data List do not change from an extremely high value, return to the Active Test menu screen, change "Check the Cylinder Compression" to "Start" and crank the engine again within 1 second.
      11. Stop cranking the engine, and then change "Check the Cylinder Compression" to "Stop" after the engine stops.
        NOTE:
        • If the Active Test is changed to "Stop" while the engine is being cranked, the engine will start.
        • After performing the Active Test, make sure to check and clear DTCs.
      12. Push the snapshot button to turn the snapshot function off.
      13. Select "Stored Data" on the Techstream screen, select the recorded data and display the data as a graph.

        HINT: 

        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.

        HINT: 

        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.

      Activate the EVAP Purge VSV - ←A ←B
      Active Test operation ON OFF
      EVAP (Purge) VSV 49.8% 0.0%
      Injector Cylinder #1 (Port) 2133 μs 3232 μs
      A/F (O2) Sensor Current B1S1 0.01 mA 0.01 mA

      HINT: 

      • Even when the Active Test is performed (the purge VSV is opened approximately 50%), 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 Cylinder #1 (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.

      NOTE:
      • Do not leave the EGR valve open for 10 seconds or more while performing 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.

      HINT: 

      • When the value of Control the EGR Step Position is "0 step", the value of Intake Manifold Absolute Pressure should be between 20 and 40 kPa (2.9 to 5.8 psi).
      • 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 Intake Manifold Absolute Pressure will increase to a value at least 10 kPa (1.45 psi) higher than the value of Intake Manifold Absolute Pressure when the value of Control the EGR Step Position was "0 step".
  30. SYSTEM CHECK 
    1. EVAPORATIVE SYSTEM CHECK

      HINT: 

      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 / Utility / Evaporative System Check.

        Powertrain > Engine > Utility 

        Tester Display
