Data List / Active Test

  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.

    1. Warm up the engine.
    2. Turn the A/C switch off.
    3. Turn the power switch off.
    4. Connect the Techstream to the DLC3.
    5. Turn the power switch on (IG).
    6. Turn the Techstream on.

    Tester Display Measurement Item/Range Normal Condition Stored as Freeze Frame Data
    Vehicle Speed Vehicle speed/
    Min.: 0 km/h (0 mph), Max.: 255 km/h (159 mph)
    Actual vehicle speed Yes
    Diagnostic Note:
    • 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

    Tester Display Measurement Item/Range Normal Condition Stored as Freeze Frame Data
    Engine Speed Engine speed/
    Min.: 0 rpm, Max.: 16383 rpm
    950 to 1050 rpm: Idling Yes
    Diagnostic Note:
    When the crankshaft position sensor is malfunctioning, "Engine Speed" is approximately 0 rpm or varies greatly from the actual engine speed.

    Tester Display Measurement Item/Range Normal Condition Stored as Freeze Frame Data
    Calculate Load Load calculated by ECM/
    Min.: 0%, Max.: 100%
    • 20 to 40%: Idling
    • 15 to 35%: Running without load (2500 rpm)
    Yes
    Diagnostic Note:
    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 manifold pressure is the same as atmospheric pressure, Calculate Load is 100%.)
    VEHICLE LOAD

    Tester Display Measurement Item/Range Normal Condition Stored as Freeze Frame Data
    Vehicle Load Vehicle load/
    Min.: 0%, Max.: 25700%
    Actual vehicle load Yes
    Diagnostic Note:
    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.)
    HINT: 
    Due to individual engine differences, intake air temperature, etc., the value may exceed 100%.
    Intake airflow (g/rev.) = Intake airflow (gm/s) x 60 / Engine speed (rpm)
    (Intake airflow (gm/s) is MAF)
    MAF

    Tester Display Measurement Item/Range Normal Condition Stored as Freeze Frame Data
    MAF Airflow rate from mass air flow meter sub-assembly/
    Min.: 0 gm/sec, Max.: 655.35 gm/sec
    1 to 3 gm/sec: Idling
    4.5 to 8.5 gm/sec: Running without load (2500 rpm)

    Tester Display Measurement Item/Range Normal Condition Stored as Freeze Frame Data
    MAP Intake manifold pressure/
    Min.: 0 kPa (0 mmHg), Max.: 255 kPa (1913 mmHg)
    • 80 to 110 kPa (600 to 825 mmHg): Power switch on (IG)
    • 20 to 40 kPa (150 to 300 mmHg): Idling
    Yes
    Diagnostic Note:
    This is the intake manifold pressure.
    This item is the pressure detected by the manifold absolute pressure sensor and is used for air fuel ratio control.
    HINT: 
    • When the power switch is on (IG), the manifold absolute pressure and atmospheric pressure are approximately the same (standard atmospheric pressure = 101 kPa (756 mmHg)).
    • As Vapor Pressure Pump together with MAP are almost the same as atmospheric pressure when the engine is stopped, these items can be used to help determine if the manifold absolute pressure sensor characteristics are abnormal, if there is noise, or if the sensor output is stuck at a certain value by comparing the values.

    THROTTLE MOTOR CURRENT

    Tester Display Measurement Item/Range Normal Condition Stored as Freeze Frame Data
    Throttle Motor Current Throttle motor current/
    Min.: 0 A, Max.: 19.9 A
    0 to 3.0 A: Idling No
    Diagnostic Note:
    • 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

    Tester Display Measurement Item/Range Normal Condition Stored as Freeze Frame Data
    Throttle Motor DUTY Throttle actuator/
    Min.: 0%, Max.: 100%
    10 to 22%: Idling after engine warmed up Yes
    Diagnostic Note:
    This is the output duty ratio of the throttle actuator drive circuit.

    0 to 40%: Idling No
    Diagnostic Note:
    This is the duty ratio used to drive the throttle actuator and close the throttle valve. It is an ECM command signal.
    HINT: 
    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.

    Tester Display Measurement Item/Range Normal Condition Stored as Freeze Frame Data
    EVAP (Purge) VSV Purge VSV control duty/
    Min.: 0%, Max.: 100%
    0 to 50%: Idling, under purge control Yes
    Diagnostic Note:
    • This is the command signal from the ECM.
    • This is the purge VSV control duty ratio. When EVAP (Purge) VSV is any value except 0%, EVAP purge* is being performed.

      *: Gasoline vapor from the fuel tank is being introduced into the intake system via the purge VSV.

    • When the engine is cold or immediately after the engine is started, EVAP (Purge) VSV is 0%.

    Tester Display Measurement Item/Range Normal Condition Stored as Freeze Frame Data
    Evap Purge Flow Purge flow/
    Min.: 0%, Max.: 399.9%
    0 to 10%: Idling Yes
    Diagnostic Note:
    This is the percentage of total engine airflow contributed by EVAP purge operation.
    (Evap Purge Flow = Purge flow / Engine airflow x 100 (%))
    It is based on MAF and a stored value for airflow and controlled by adjusting the duty cycle for the purge VSV.
    PURGE DENSITY LEARN VALUE

    Tester Display Measurement Item/Range Normal Condition Stored as Freeze Frame Data
    Purge Density Learn Value Purge density learned value/
    Min.: -200, Max.: 199.993
    -40 to 10: Idling Yes
    Diagnostic Note:
    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%.
    HINT: 
    • 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.

    Min.: 0 kPa (0 mmHg), Max.: 1441.77 kPa (10815.979 mmHg)
    Approximately 100 kPa (750 mmHg) (absolute): Power switch on (IG) No
    Diagnostic Note:
    This is the EVAP system pressure monitored by the canister pressure sensor.
    HINT: 
    • Except for when the monitor is running, this value should be approximately the same as atmospheric pressure.
    • As MAP with Vapor Pressure Pump are almost the same as atmospheric pressure when the engine is stopped, these items can be used to help determine if the canister pressure sensor characteristics are abnormal, if there is noise, or if the sensor output is stuck at a certain value.
    VAPOR PRESSURE (CALCULATED)

    Min.: -100%, Max.: 99.2%
    -20 to 20% Yes
    Diagnostic Note:
    The ECM will learn the Long FT values based on Short FT. The goal is to keep Short FT at 0% to keep the A/F mixture at the stoichiometric ratio.
    This value is used to determine whether the system related to air-fuel ratio control is malfunctioning (it is possible to check this value for each bank).
    The condition of the system is determined based on the sum of Short FT and Long FT (excluding times when the system is in transition).
    • +20% or more: There may be a lean air-fuel ratio.
    • -20 to +20%: The air-fuel ratio can be determined to be normal.
    • -20% or less: There may be a rich air-fuel ratio.
    • The learned value is cleared when the auxiliary battery cable is disconnected.
    • Air-fuel ratio feedback leaning is divided up according to the engine operating range (engine speed x load), and separate value are stored for each operating range. "Long FT #1" indicates the learned value for the current operating range.

      [A/F Learn Value Idle #1], [A/F Learn Value Low #1], [A/F Learn Value Mid1 #1], [A/F Learn Value Mid2 #1] and [A/F Learn Value High #1] indicate the leaned values for the different operating ranges.

    Min.: -1024°CA, Max.: 1023.9°CA
    -20 to 0°CA
    Driving at 70 km/h (43 mph)
    Yes
    Diagnostic Note:
    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 amount
    Example: 21°CA = 10° + 14° - 3°
    *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 more 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.

    HINT: 
    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

    Tester Display Measurement Item/Range Normal Condition Stored as Freeze Frame Data

    Min.: -1024°CA, Max.: 1023.9°CA
    0 to 22°CA
    Driving at 70 km/h (43 mph)
    Yes
    Diagnostic Note:
    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.
    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 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.).

    Min.: -128%, Max.: 127%
    -100 to 99.2% Yes
    Diagnostic Note:
    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 not determined to be misfiring, Misfire Margin = 52%.
    When the engine is determined to be misfiring, Misfire Margin = -128 to 0%.

      12. Monitor the engine speed (Engine Speed of Cyl #1 to #4 and Av Engine Speed of All Cyl) displayed on the Techstream.
        NOTE:
        • When the Check the Cylinder Compression Active Test is turned ON, the engine will start.
        • 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.
        • Use a fully-charged auxiliary battery.

        HINT:

      HINT: 

      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) 2267.0 μs 2489.0 μs

      HINT: 

      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.

      Tester Display Measurement Item/Range Normal Condition
      Control the VVT Linear (Bank 1) - ←A ←B
      Active Test operation* +30% -30%
      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%

      HINT: 

      • *: Change the control value for Control the VVT Linear to +30% or -30% in increments of 5%.
      • 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 #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 park (P) selected during charge control. Move shift lever to N to perform test.
  21. 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 power switch on (IG).
    3. Turn the Techstream on.
    4. Enter the following menus: Powertrain / Engine and ECT / Utility.
    5. Perform the System Check by referring to the table below.
