SFI SYSTEM VEHICLE CONTROL HISTORY

DESCRIPTION (SFI SYSTEM)(w/ Differential Pressure Sensor)

• 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.

PRECAUTIONS (SFI SYSTEM) (w/ Differential Pressure Sensor)

• 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.

CHECK VEHICLE CONTROL HISTORY (SFI SYSTEM) (w/ Differential Pressure Sensor)

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

   Tech Tips

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

   Vehicle Control History Item

   Code	Item	Trigger Description	Stored Group	Reference Inspection Procedure	Link
   X0856	GPF Rejuvenate Interruption	When normal PM (Particulate Matter) regeneration stops	0A	-	-
   X0857	GPF Rejuvenate Run Insufficiency	The air-fuel ratio conditions are met at 60 km/h (37 mph) or more, but the temperature required for PM regeneration has not been reached	0A	-	-
   X0858	Particulate Filter Differential Pressure High	When the GPF upstream exhaust pressure measured by the differential pressure sensor (GPF differential pressure calibration value) exceeds the threshold value due to the accumulation of PM or ash (metal oxide) Tech Tips When this code is detected, output is limited and the "Reduced Engine Power" warning message is displayed on the multi-information display.	0A	Refer to the P244B00 inspection procedure	Click here
   X0859	Particulate Filter Differential Pressure Too High	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 sensor determines the pressure is high (X0858) Tech Tips When this code is detected, output is limited and the "Reduced Engine Power" warning message is displayed on the multi-information display.	0A	Refer to the P244B00 inspection procedure	Click here
   X085C	Over Temperature Prevention when Particulate Filter Over Accumulation	When the PM deposition ratio is at or above the specified value Tech Tips When this code is detected, output is limited and the "Reduced Engine Power" warning message is displayed on the multi-information display.	0A	Refer to the P246300 inspection procedure	Click here

   Stored Data

   Stored Group	Number of Records	Number of Freeze Frame Points	Multi Freeze Frame Data Sampling Period	Note
   0A	4 code 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.

   Tech Tips

   
   

   • Multi Freeze Frame Data makes it possible to display the engine condition (ECU data) both before and after the trigger detection point.

   • The number of available points differs depending on the stored group.

   • When the value of a data item does not change across all points, only the value at the detection point will be displayed.

   • Only 1 measurement point can be displayed for stored group 05 and 0A Freeze Frame Data.
