Abstract—This article presents the test methods of UDS (Unified Diagnostic Services) diagnostic protocol stack in vehicles, which includes two parts. One is the unit test of the main functions in network layer, another one is the functional test of the network and application layer. Corresponding test environments based on software and hardware are designed. Test cases are created according to international standard. All these tests ensure the efficiency of the development and the accuracy and standard of target protocol stack. Finally the designed test system is verified correctly.

Index Terms—UDS, diagnostic protocol stack, unit test, functional test
