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 neutral, 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.

    • 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.
    MAP Intake manifold pressure Min.: 0 kPa (0 mmHg), Max.: 255 kPa (1912 mmHg)

    This is the intake manifold pressure.

    This item is the pressure detected by the vacuum sensor (manifold absolute pressure sensor).

    Tech Tips

    When the engine switch is on (IG), the manifold absolute pressure and atmospheric pressure are approximately the same (standard atmospheric pressure = 101 kPa(abs) [758 mmHg(abs)]).

    Long FT B1S1 Long-term fuel trim for bank 1 Min.: -100.000 %, Max.: 99.200%

    • The ECM will learn the Long FT #1 values based on Short FT #1. The goal is to keep Short FT #1 at 0% to keep the air fuel ratio mixture at the stoichiometric ratio.

    • This value is used to determine whether the system related to air fuel ratio control is malfunctioning.

    • The condition of the system is determined based on the sum of Short FT #1 and Long FT #1 (excluding times when the system is in transition).


      • The condition of the system is determined based on the sum of Short FT #1 and Long FT #1 (excluding times when the system is in transition).

      • -15 to 15%: The air fuel ratio can be determined to be normal.

      • -15% or less: There may be a rich air fuel ratio.

      • Air fuel ratio feedback learning is divided up according to the engine operating range (engine speed x load), and a separate value is 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 learned values for the different operating ranges. The learned value that is the same as "Long FT #1" indicates the current engine operating range.

    IGN Advance Ignition timing advance for No. 1 cylinder Min.: -64.0 deg, Max.: 63.5 deg -
    Knock Feedback Value Knocking feedback value Min.: -1024.0 deg(CA), Max.: 1023.9 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 sensor sensitivity.

    • The knock sensor is improperly installed.

    • There is a problem with a wire harness.

    System Identification System identification - Used for identifying the engine system: Gasoline
    System Guard System guard ON or OFF

    • 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.
    Throttle Idle Position Whether or not throttle position sensor detecting idle ON or OFF

    • This is a parameter calculated by the ECM.

    • The value is ON when the throttle is at the idle position and OFF when the throttle is open.
    Throttle Require Position Required throttle position Min.: 0.000 V, Max.: 4.980 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.: 0.0%, Max.: 100.0%

    • This is the throttle valve opening amount used for engine control. (100.0% 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 engine switch is on (IG) and the engine is stopped.

    Throttle Position Command Throttle position command value Min.: 0.00 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.: 0.00 V, Max.: 4.98 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 engine switch is on (IG).
    Throttle Sens Open Pos #2 No. 2 throttle position sensor Min.: 0.00 V, Max.: 4.98 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 engine switch is on (IG).
    Throttle Motor DUTY Throttle actuator Min.: 0%, Max.: 100% 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% This is the duty ratio used to drive the throttle actuator and open the throttle valve. It is an ECM command signal.
    Throttle Motor Duty (Close) Throttle actuator duty ratio (close) Min.: 0%, Max.: 255%

    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.: 0.000 V, Max.: 4.980 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 engine switch on (IG)., the accelerator pedal is released and the throttle actuator is off).

    • Learning is performed immediately after the engine switch on (IG).
    +BM Voltage +BM voltage Min.: 0.000 V, Max.: 79.998 V 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 engine switch is turned off).
    Actuator Power Supply Actuator power supply ON or OFF If +BM power is lost, this item changes to OFF.
    Throttle Position Throttle valve opening angle Min.: 0.00 deg, Max.: 499.99 deg This value has no meaning when the engine switch on (IG) and the engine is stopped.
    Atmosphere Pressure Atmospheric pressure Min.: 0 kPa (0 mmHg), Max.: 255 kPa (1912 mmHg)

    • This value is calculated from the intake air amount.

    • Standard atmospheric pressure: 101 kPa(abs) [758 mmHg(abs)]

    • For every 100 m (328 ft) increase in altitude, pressure drops by 1 kPa (7.5 mmHg). This varies by weather.

  3. 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 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 / Active Test.

    7. According to the display on the GTS, perform the Active Test.

      Powertrain > Engine > Active Test
