Description:
|
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 . |
