M20F-FXS, M20G-FXS ENGINE CONTROL SFI SYSTEM VEHICLE CONTROL HISTORY (RoB)
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 stalled 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 are almost the same as those of the Data List.
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.
CHECK VEHICLE CONTROL HISTORY (RoB) (SFI SYSTEM)
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Enter the following menus: Powertrain / Engine / Utility / Vehicle Control History (RoB).
- Powertrain > Engine > Utility
-
Tester Display Vehicle Control History (RoB) - 50005 372 55
- HINT:
-
It is also possible to display Vehicle Control History during the Health Check, if "Store All Data" is selected.
| Code | Item | Trigger Description | Stored Group | Reference Inspection Procedure | Link |
|---|---|---|---|---|---|
| X0856 | GPF Rejuvenate Interruption | When normal PM (Particulate Matter) regeneration stops | 15 | Check the Vehicle Control History Freeze Frame Data items "GPF Rejuvenate Impossibility History" | ( 202307,999999,_51,_144956,_0604911,RM100000002BWT9,)
|
| 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 | 15 | Check that the vehicle was driven in the specified manner, and then increase the vehicle speed and perform particulate filter rejuvenation again.
Refer to Particulate Filter Regenerate Procedure |

|
| 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 | (202307,999999,_51,_144956,_0604911,RM100000002BWTB,P244B00)
|
| 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 | (202307,999999,_51,_144956,_0604911,RM100000002BWTB,P244B00)
|
| 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 Particulate Filter Regeneration Procedure | (202307,999999,_51,_144956,_0604911,RM100000002BWT9,)
|
| X085E | GPF/DPF Clogged Level 2 | When the customer has performed particulate filter regenerate | 15 | Refer to Particulate Filter Regeneration Procedure | (202307,999999,_51,_144956,_0604911,RM100000002BWT9,)
