Toyota Corolla Cross: VEHICLE CONTROL HISTORY (RoB)

Toyota Corolla Cross (2022-2024) Service Manual / Suspension / Tire Pressure Monitoring / Tire Pressure Warning System / VEHICLE CONTROL HISTORY (RoB)

VEHICLE CONTROL HISTORY (RoB)

DESCRIPTION

Vehicle Control History (RoB) is a function that captures and stores ECU data when triggered by specific vehicle behavior.
It may be possible to determine 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 (RoB) 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 content of the Freeze Frame Data is almost the same as that of the Data List.
