Automobile fault detection and diagnosis technology has always been a hot topic for the foreign and domestic scholars. In order to solve the problem of remote fault detection for auto repair,designs and implements a vehicle fault information collection node,using such tech-nology as OBDII、GPRS and GPS. The node is based on STM32F103. Uses ODBII module,GPRS module and GPS module,it can acqui-sition automobile fault information,longitude,latitude,speed,and then process,store them. Afterwards,the information is sent to mainte-nance management center by radio. Test results show that this node has steady performance and high practicality.
