As an automotive diagnostic technology, the UDS (unified diagnostic services) protocol has been more and more widely applied. In this paper, a diagnosis system based on UDS is developed and tested. According to the UDS protocol, the software is designed and groups of diagnostic services are implemented. Besides, the host computer is designed so that the results of diagnosis can be parsed and displayed clearly. The host computer is divided into two types: one is implemented on PCs, which the

Finally, in order to verify the diagnostic system, we carry out some test cases and draw the conclusions that the diagnostic system is feasible.
