SFI SYSTEM VEHICLE CONTROL HISTORY

  1. DESCRIPTION (SFI SYSTEM)

    • Vehicle Control History is a function that captures and stores ECU data when triggered by specific vehicle behavior.

    • The number of possible stored Freeze Frame Data sets, whether multi Freeze Frame Data is available, the number of freeze frame points, Freeze Frame Data items, the ECU internal range, etc., is different depending on the stored group.

    • The stored data items for Vehicle Control History Freeze Frame Data are different depending on the stored group. When the value of a data item does not change across all points, only the value of the detection point will be displayed. The contents of the Freeze Frame Data is almost the same as that of the Data List.

  2. PRECAUTIONS (SFI SYSTEM)

    • As Vehicle Control History may be overwritten whenever the trigger conditions are met, make sure to save Vehicle Control History before performing any inspections.

    • As Vehicle Control History may be stored when performing an Active Test, learning, etc., make sure to clear the Vehicle Control History before returning the vehicle to the customer.

  3. CHECK VEHICLE CONTROL HISTORY (SFI SYSTEM)

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine / Utility / Vehicle Control History (RoB).

      Powertrain > Engine > Utility

      Tester Display

      Vehicle Control History (RoB)
      Tip:

      It is also possible to display Vehicle Control History during the Health Check, if "Store All Data" is selected.

      Particulate Filter Differential Pressure Too High Bank1

      When the GPF upstream exhaust pressure measured by the differential pressure sensor (GPF differential pressure calibration value) exceeds the threshold value due to further PM and ash being accumulated in the GPF after the GPF differential pressure sensor determines the pressure is high (X0858)

      Tip:

      • If the detection conditions for a code that is not currently stored are met, the code will be stored.

      • If the detection conditions for a code that is currently stored are met again in the same trip, the code will not be overwritten.

      • If the detection conditions for a code that is currently stored are met again in a different trip, the code will be overwritten.

      1 point (multi Freeze Frame Data not available)

      -

      The data can be cleared by using the GTS or by disconnecting the cable from the negative (-) battery terminal.
      Tip:

      Only 1 measurement point can be displayed for stored group 0A Freeze Frame Data.
