SFI SYSTEM DATA LIST / ACTIVE TEST


  1. DATA LIST

    Tech Tips

    Using the intelligent tester 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 for reference only. Do not depend solely on these values when determining whether or not a part is faulty.


    1. Warm up the engine.

    2. Turn the ignition switch off.

    3. Connect the intelligent tester to the DLC3.

    4. Turn the ignition switch to ON.

    5. Turn the tester on.

    6. Enter the following menus: Powertrain / Engine and ECT / Data List.

    7. Check the values by referring to the table below.

    Tech Tips

    If no idling conditions are specified, the transmission gear should be in the neutral position, and the A/C switch and all accessory switches should be off.

  2. ACTIVE TEST

    Tech Tips

    Using the intelligent tester 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.


    • Data List can be displayed during Active Test.


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the tester on.

    4. Enter the following menus: Powertrain / Engine and ECT / Active Test.

    5. Perform the Active Tests by referring to the table below.

    Tester Display Test Part Control Range Diagnostic Note
    Control the Injection Volume Change injection volume Between -12.5 and 25.0%

    • All fuel injectors tested at same time


    • Confirm that the engine speed is 3000 rpm or less


    • Injection volume can be changed in 0.1% graduations within control range
    Control the Injection Volume for A/F Sensor Change injection volume Lower by 12.5% or increase by 25.0%

    • Confirm that the engine speed is 3000 rpm or less

    • Control the Injection Volume for A/F Sensor enables checking and graphing of A/F (Air Fuel Ratio) sensor and Heated Oxygen (HO2) sensor voltage outputs

    • To conduct test, enter the following menus: Active Test / Control the Injection Volume for A/F Sensor / Data List / A/F Control System / AFS Voltage B1S1 and O2S B1S2
    Control the EGR Step Position Open or closed EGR valve From 0 to 110 steps

    • EGR valve fully closed at step position 0, and fully open at step position 110

    • Amount of EGR gas, flowing into intake manifold, varies in accordance with EGR valve opening angle

    Control the ETCS Open/Close Slow Speed Throttle actuator ON: Throttle valve opens/closes slowly

    Test is possible when following conditions are met:


    • Engine is stopped


    • Shift lever in P


    • Accelerator pedal fully depressed.
    Control the ETCS Open/Close Fast Speed Throttle actuator ON: Throttle valve opens/closes fast

    Control the All Cylinders Fuel Cut All cylinders injector fuel cut ON/OFF

    Shift lever in P

    Test is possible with vehicle stopped
    Check the Cylinder Compression Check cylinder compression pressure ON/OFF *1

    Tech Tips

    *1: When performing the Active Test item "Check the Cylinder Compression" and then cranking the engine, the ECM stops fuel injection and the ignition, and measures the engine speed for each cylinder.

    If one cylinder speed is higher than the others, that cylinder's compression pressure can be concluded to be lower than the others.


    1. Warm up the engine.

    2. Turn the ignition switch off.

    3. Connect the intelligent tester to the DLC3.

    4. Turn the ignition switch to ON.

    5. Turn the tester on.

    6. Enter the following menus: Powertrain / Engine and ECT / Active Test / Check the Cylinder Compression.

    7. Select the following monitor items: Engine Speed of Cyl #1 to #3, Av Engine Speed of All Cyl

    8. Press the RIGHT or LEFT button to change the Check the Cylinder Compression to ON.

      Tech Tips

      Fuel injection and ignition for all cylinders are prohibited at this time, and each cylinder's engine speed measurement will enter standby mode.

    9. Crank the engine until the monitor item values "Engine speed of Cyl #1 to #3" and "Av Engine Speed of All Cyl" change

    10. Monitor the engine speed (Engine Speed of Cyl #1 to #3, Av Engine Speed of All Cyl) displayed on the tester.

      Tech Tips

      The tester displays the values to be extremely high before cranking the engine. Each cylinder's engine speed is measured while cranking the engine and then the tester displays the actual engine speed values.

      Note


      • The Active Test item "Check the Cylinder Compression" will automatically turn off 255 seconds after the Active Test is turned on.

      • When the "Check the Cylinder Compression" is OFF and the engine is cranked, the engine will start.

      • If the "Check the Cylinder Compression" test needs to be performed again after each cylinder's engine speed measurement has been performed once, press EXIT to return to the Active Test menu screen. Then perform the Check the Cylinder Compression test again.

      • Use a fully-charged battery.
