So the development and application of ITS (Intelligent Transportation System, Intelligent Transportation Systems) capture attention gradually, especially the safety traffic area is important. The condition information saved in the vehicle can be received through OBD-II (the Second On-Board Diagnostics, board automatic diagnostic system) interface. As long as presented more clearly and convenient, it can help driver grasp the condition of the vehicle more accurately. In this paper we propose an Android application via WIFI wireless signals to communicate with OBD-II in the Android based smart device. To access the condition information immediately and to parse the DTC (Diagnostic Trouble Codes) that recorded in the vehicle''s chip after receiving. Not only eliminates the process which use OBD testing equipment (OBD Scan Tool) into the plant, but also understands the condition more immediate and accurately before driving. Recording the driving motion track information with the vehicle driving video provides more complete motion track records. And it''s different from commercially available tachograph only skimming lane images. It will be a great benefit to determine the responsibility belong to when the accident occurred.
