This project deals with developing a system, which can be implemented by Texas Department of Transportation, as a part to develop a PC based universal scan tool, which can later be used to create a database on the different tests and use for future research. A microprocessor based physical layer for OBD II test equipment that can be used to test any car that supports the ON-Board Diagnostics II protocol has been developed. This acts as the interface tool between the OBD II system on the vehicle and the application layer residing on the PC. The verification of the system has been done, by generating sample data that matches real time data. Conclusions and suggestions for future work are discussed.
