Patent 7577503 was granted and assigned to SPX Corporation on August, 2009 by the United States Patent and Trademark Office.
A diagnostic tool with an adaptive method is provided that will adaptively change the time interval at which the tool interrogates the vehicle if the tool determines if a diagnostic test is not progressing. The tool can interrogate at that interval until it reaches the iteration limit. The tool can also restart at the previous time interval and iteration limit if the tool recognizes that it was previously communicated with the vehicle.
