In some series of Tohatsu engines the storage of errors by the injection control unit does not distinguish between ACTIVE and STORED condition, but the two conditions are always notated by "ATT" (active).
To check if the read error is relative to an actual malfunction, you must try to delete the error.
If it is impossible to delete the error it means that it is active. If it becomes "STO" it must be considered as registered or casual error.
