SFI SYSTEM(for Rear Air Fuel Ratio Sensor) VEHICLE CONTROL HISTORY

DESCRIPTION (SFI SYSTEM (w/o Canister Pump Module))

• 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/o Canister Pump Module))

• 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/o Canister Pump Module))

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.

   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 Bank1	When the GPF (Gasoline Particulate Filter) 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)	0A	Refer to the P244B00 inspection procedure	Click here
   X0859	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)	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 and GPF temperature is at or above the specified value	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 codes 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

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

CLEAR VEHICLE CONTROL HISTORY (SFI SYSTEM (w/o Canister Pump Module))

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) (Clear).

   
   Powertrain > Engine > Utility

   Tester Display
   Vehicle Control History (RoB)

   Note

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