Abstract

This project deals with developing a system, which can be implemented by TNRCC (Texas natural resource conservation Commission), as a part of State implementation plan to verify compliance with EPA (Environment Protection Agency) program performance standards. In the process, a Universal scan tool has been designed, in accordance with the EPA and Society of Automotive Engineers (SAE specifications). The system developed here not only acts as scan tool to diagnosis the trouble code, but also aids in computer interface, which helps TNCC to maintain a database of all the cars in Texas, with their emission-related data. A design of universal scan tool is discussed from software perspective. The results of this system were compared by actually plugging in a scan tool into the 1996 and 1997 model vehicles. The conclusions and recommendations for future work are discussed.
