Toyota Corolla Cross: 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.
- 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 (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 contents of the Freeze Frame Data are almost
the same as those of the Data List.
