In order to detect the fault of automotive Electronic Control Units. In this paper, we proposed and implemented Controller Area Network (CAN) node management mechanism in the light of CAN technology standards and OSEK / VDX specifications. Besides, the standard protocols for analyzing low-speed CAN network application messages and monitoring network management messages had been developed. We utilized the vehicle network remote fault diagnosis platform and CAN analysis tool ZLGCANTEST to test the CAN data and analyze its real-time monitoring state. The experiment results indicate that CAN node management is capable of rapidly completing node fault detecting and promptly report node fault information for vehicle network remote fault diagnosis.
