SFI SYSTEM(w/ GPF) VEHICLE CONTROL HISTORY


  1. VEHICLE CONTROL HISTORY (AIRBAG SYSTEM)

    Tech Tips

    A part of the control history can be confirmed using the vehicle control history.

  2. DESCRIPTION (SFI SYSTEM)


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

    • If the customer states that the engine stalls or will not start, it may be possible to diagnose the cause of the malfunction by checking the vehicle history information and freeze frame data.

    • 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.

  3. 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.

  4. CHECK VEHICLE CONTROL HISTORY (SFI SYSTEM)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    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)

      Tech Tips

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

      Tech Tips


      • 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.

  5. CLEAR VEHICLE CONTROL HISTORY (SFI SYSTEM)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    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)

      Note

      By performing this procedure, all stored Vehicle Control History items will be cleared.

  6. VEHICLE CONTROL HISTORY FREEZE FRAME DATA (SFI SYSTEM)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    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)

    5. Select a vehicle control history item to access the applicable freeze frame data.

    6. Check the freeze frame Data recorded with the Vehicle Control History.
