Abstract: For carrying out teaching practice of car network application technology course of the automotive intelligent technology major，this paper used automotive instruments as test objects，took the Kavser CAN analyzer to transmitted the test data to the USB interface CAN analyzer with C# designed instrument test program，then transmitted to instrument bus through CAN interface of transmission analyzer，and drove the automotive instrument modules′ operation，implemented instrument speed，engine speed，engine water temperature and light tests. Thus the test system can be used as a teaching and training platform for sharing core courses of automotive intelligent technology major.

Key words: CAN analyzer, automotive instrument test, teaching practice platform
