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.

    • The actual values may differ from the values listed in the chart under "Reference Value" due to climate, weather conditions, etc.

    Tech Tips

    Normal Condition: If no conditions are specifically stated for "idling", the shift lever should be in P or N, 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 ignition switch off.

  2. Various Vehicle Conditions 1 (All Data)


    Powertrain > Engine and ECT > Data List
    Tester Display Measurement Item Range Normal Condition Reference Value 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.


      • There is a delay in when the vehicle speed data 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 610 to 710 rpm: Idling with warm engine, shift lever in N, A/C off Idling (engine warmed up and A/C off): 669 rpm 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% -
    • Ignition switch ON: 0.0%

    • Idling (engine warmed up): 24.7%

    • Running without load (3000 rpm): 23.1%


    • 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 Vehicle load Min.: 0%, Max.: 25700% -
    • Ignition switch ON: 0.0%

    • Idling (engine warmed up): 13.7%

    • Running without load (3000 rpm): 13.7%


    • This is the engine intake air charging efficiency.

    • Vehicle Load = Current intake airflow (gm/sec) / maximum intake airflow x 100%

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

    Tech Tips

    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 value)

    MAF Airflow rate from mass air flow meter sub-assembly Min.: 0 gm/sec, Max.: 655.35 gm/sec
    • 1.0 to 3.0 gm/sec: Idling with warm engine (A/C off and shift lever in N)

    • 8.0 to 22.0 gm/sec: 3000 rpm (A/C off and shift lever in N)


    • Ignition switch ON: 0.50 gm/sec

    • Idling (engine warmed up): 2.31 gm/sec

    • Running without load (2500 rpm): 8.60 gm/sec

    • Running without load (3000 rpm): 10.20 gm/sec

    This is the intake air amount from the mass air flow meter sub-assembly.
    Atmosphere Pressure Atmospheric pressure Min.: 0 kPa (0 psi), Max.: 255 kPa (36.98 psi) Equivalent to atmospheric pressure (absolute pressure) Idling (engine warmed up): 99 kPa(abs) [14.36 psi(abs)]
    • This value is calculated from the intake air amount.

    • Standard atmospheric pressure: 101 kPa(abs) [14.65 psi(abs)]

    • For every 100 m (328 ft) increase in altitude, pressure drops by 1 kPa (0.15 psi). This varies by weather.

    Coolant Temp Engine coolant temperature Min.: -40°C (-40°F), Max.: 140°C (284°F) 75 to 100°C (167 to 212°F): After warming up -

    This is the engine coolant temperature.

    Tech Tips


    • 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 140°C (284°F), the sensor circuit is open or shorted.

    • Check if the engine overheats when the value indicates 140°C (284°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 -

    This is the intake air temperature.

    Tech Tips


    • 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 140°C (284°F), the sensor circuit is open or shorted.

    Ambient Temperature Ambient temperature Min.: -40°C (-40°F), Max.: 215°C (419°F) Actual ambient temperature -

    This is the ambient temperature.

    Tech Tips

    If the vehicle has been left as is for a long time after the ignition switch was turned off, coolant temperature, intake air temperature and ambient temperature will be almost the same.

    Engine Run Time Engine run time Min.: 0 s, Max.: 65535 s Time after engine start -

    This is the time elapsed since the engine was started.

    Tech Tips

    The time is counted only while the engine is running.

    Initial Engine Coolant Temp Initial engine coolant temperature Min.: -40°C (-40°F), Max.: 119.3°C (246.7°F) - - This is the engine coolant temperature stored when the ignition switch is turned to ON.
    Initial Intake Air Temp Initial intake air temperature Min.: -40°C (-40°F), Max.: 119.3°C (246.7°F) - - This is the intake air temperature stored when the ignition switch is turned to ON.

    • Ignition switch ON: 82.3% (accelerator pedal fully depressed)

    • Idling (engine warmed up): 14.9%

    • Running without load (3000 rpm): 18.8%

    The No. 1 throttle position sensor output is converted using 5 V = 100%.

    Tech Tips

    • Idling (engine warmed up): 46.6%

    The No. 2 throttle position sensor output is converted using 5 V = 100%.
    ST1 Brake pedal signal ON or OFF
    • ON: Brake pedal depressed

    • OFF: Brake pedal released

    - This is the stop light switch assembly signal (ST1- terminal).
    System Guard System guard ON or OFF ON Idling (engine warmed up): 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 -
    • Ignition switch ON: OFF

    • Idling (engine warmed up): ON

    • Ignition switch ON: 0.820 V (accelerator pedal fully released)

    • Ignition switch ON: 4.121 V (accelerator pedal fully depressed)

    • Idling (engine warmed up): 0.742 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 wheelspin control.
    Throttle Sensor Position Throttle sensor position Min.: 0%, Max.: 100%
    • 0%: Accelerator pedal fully released

    • 50 to 80%: Accelerator pedal fully depressed

    Idling (engine warmed up): 0.0%
    • 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.

    Throttle Position No.1 No. 1 throttle position sensor output voltage Min.: 0 V, Max.: 4.98 V

    Almost same as "Throttle Require Position"

    This is the No. 2 throttle position sensor 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 No. 1 throttle position sensor Min.: 0 V, Max.: 4.98 V 0.6 to 1.4 V Ignition switch ON: 0.917 V This is the No. 1 throttle position sensor 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 No. 2 throttle position sensor Min.: 0 V, Max.: 4.98 V 1.7 to 2.5 V Ignition switch ON: 2.011 V This is the No. 2 throttle position sensor 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 (A/C off and shift lever in N)
    • Ignition switch ON: 0.0 A (accelerator pedal fully released)

    • Ignition switch ON: 0.8 A (accelerator pedal fully depressed)

    • Idling (engine warmed up): 0.8 A

    • Running without load (3000 rpm): 0.6 A


    • 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 (A/C off and shift lever in N) - 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 (A/C off and shift lever in N)

    Throttle Motor Duty (Close) Throttle actuator duty ratio (close) Min.: 0%, Max.: 255% 0 to 40%: Idling (A/C off and shift lever in N)
    • Ignition switch ON: 0% (accelerator pedal fully released)

    • Ignition switch ON): 0% (accelerator pedal fully depressed)

    • Idling (engine warmed up): 16%

    • Running without load (3000 rpm): 0%

    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.

    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 Ignition switch ON: 0.644 V
    • 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.

  6. Idle Speed Control (Ptrl Rough Idle)


    Powertrain > Engine and ECT > Data List
    Tester Display Measurement Item Range Normal Condition Reference Value Diagnostic Note
    ISC Position Requested throttle opening amount calculated using ISC control Min.: 0 deg, Max.: 499.99 deg - Idling (engine warmed up): 2.80 deg This is the throttle valve opening amount while the engine is idling (the throttle valve opening amount necessary to maintain ISC air flow).
    Low Revolution Control Low engine speed control operation state ON or OFF - Idling (engine warmed up): 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.

        Tech Tips

        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.

    N Range Status Shift lever N status ON or OFF ON: Shift lever is P or N - -
    ISC Feedback Learning Torque ISC feedback learning torque Min.: -1024 Nm, Max.: 1023.96 Nm -7 to 15 Nm: Idling (A/C off and shift lever in N) Idling (engine warmed up): -0.29 Nm

    The compensation value to make the engine run at the target idle speed. This value expresses the difference from the estimated torque. For example, when the ISC feedback learning torque is "+", maintaining the idle speed requires more torque than the estimated torque.

    Tech Tips


    • When the absolute value of the "ISC Feedback Torque" exceeds a certain value, that absolute value is gradually taken into account in the "ISC Feedback Learn Torque".

    • When the engine is operating stably near the target idle speed, the following relational expression can be derived.

      ISC torque (ISC total torque) = "ISC Feedback Learn Torque" + "ISC Feedback Torque" + "ISC Feedback Torque (Recent)" + "ISC Total AUXS Torque"

    ISC Total AUXS Torque ISC total AUXS torque Min.: -1024 Nm, Max.: 1023.96 Nm 8 to 25 Nm: Idling (A/C off and shift lever in N) Idling (engine warmed up): 16.31 Nm The total of each estimated load torque when the engine is idling. (The total load torque of the engine's friction, alternator, air conditioner, A/T, etc.)
    ISC Feedback Torque ISC feedback torque Min.: -1024 Nm, Max.: 1023.96 Nm -7 to 15 Nm: Idling (A/C off and shift lever in N) Idling (engine warmed up): -0.82 Nm

    This expresses the feedback compensation value (torque) to make the engine run at the target idle speed.

    Tech Tips

    When the engine does not run at the target idle speed, the "ISC Feedback Torque" increases or decreases.

    ISC Feedback Torque(Recent) ISC feedback torque (recent) Min.: -1024 Nm, Max.: 1023.96 Nm -5 to 5 Nm: Idling (A/C off and shift lever in N) Idling (engine warmed up): 0.03 Nm

    This expresses the feedback compensation value (torque) that first moves to make the engine run quickly at the target idle speed.

    Tech Tips

    When the engine does not run at the target idle speed, the "ISC Feedback Torque (Recent)" first increases or decreases, and subsequently, that decrease or increase is conveyed to the "ISC Feedback Torque" (which controls the amount of air).

    ISC AUXS Torque(Alternator) ISC AUXS torque (alternator) Min.: -1024 Nm, Max.: 1023.96 Nm 0 to 30 Nm: Idling (A/C off and shift lever in N) Idling (engine warmed up): 5.87 Nm This expresses the ISC compensation amount (estimated torque) according to the alternator's load.
    ISC AUXS Torque(Air Conditioner) ISC AUXS torque (air conditioner) Min.: -1024 Nm, Max.: 1023.96 Nm 5 to 25 Nm: Idling (A/C and shift lever in N) Idling (engine warmed up): 0.00 Nm This expresses the ISC compensation torque (estimated torque) according to the air conditioner compressor's load.

    IGN Advance Ignition timing advance for No. 1 cylinder Min.: -64 deg, Max.: 63.5 deg 5 to 20 deg: Idling with warm engine (A/C off and shift lever in N)
    • Idling (engine warmed up): 12.5 deg

    • Running without load (3000 rpm): 45.0 deg

    -
    Knock Feedback Value Knocking feedback value Min.: -1024 deg(CA), Max.: 1023.9 deg(CA) -
    • Idling (engine warmed up): -3.0 deg(CA)

    • Running without load (3000 rpm): -3.0 deg(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 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 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 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.

    -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) -
    • Idling (engine warmed up): 19.0 deg(CA)

    • Running without load (3000 rpm): 17.4 deg(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.).

  28. 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.

    • As DTCs may be stored when an Active Test or learning is performed, make sure to clear the DTCs before returning the vehicle to the customer.


    1. Warm up the engine.

    2. Turn the ignition switch off.

    3. Connect the GTS to the DLC3.

      Tech Tips

      *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.

        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 Active Test button to change Check the Cylinder Compression to ON.

        Tech Tips

        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.

        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 #4) displayed on the GTS.

        Tech Tips

        At first, the GTS displays 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.

        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.

        • Make sure the battery is fully charged before performing this Active Test.

      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.

        • When performing the Active Test, DTC P1604 (Startability Malfunction) may be stored.

        • 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 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.

      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.

        Tech Tips

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

        GTS Display Measurement Item Normal Condition
        Control the Injection Volume for A/F Sensor - ▲A ▲B
        Active Test operation -12.5% 12.5%
        AFS Voltage B1S1 3.912 V 2.853 V
        O2S B1S2 0.055 V 0.955 V

        Tech Tips


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

        • 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%.

        • The air fuel ratio sensor has an output delay of a few seconds and the heated oxygen sensor has a maximum output delay of approximately 20 seconds.

        • If the sensor output voltage does not change (almost no reaction) while performing the Active Test, the sensor may be malfunctioning.

      • *3: Control the ETCS Open/Close Fast Speed [Active Test for electrical throttle control system] (Ignition switch ON, accelerator pedal fully depressed)

        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.

        AFS Voltage B1S1 3.327 V 3.249 V

        Tech Tips


        • Even when the Active Test is performed (the purge VSV is opened approximately 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.
