Patent 7328093 was granted and assigned to SPX Corporation on February, 2008 by the United States Patent and Trademark Office.
A diagnostic tool and method are provided wherein the diagnostic tool can function as an inspection tool and a scan tool. The diagnostic tool determines if it is authorized for an inspection and then functions as an inspection tool and does not allow the scan tool function until the inspection is completed or voided. A software of the diagnostic tool includes a shared code, an inspection tool mode and a scan tool mode. The scan tool code and the inspection code are not shared so that updating of one code does not affect the code of the other.
