Applications of On-Board Diagnosis Via CAN and GPRS Technologies
On-Board Diagnostic (ODB) system of a vehicle is used to detect the engine operation situations for the emission pollution monitor. This paper studies the prototype of the system with the applications of CAN, GPRS, and ODB II. That will help technicians or drivers to understand what happens according to the Diagnostic Trouble Codes (DTCs) after the DTCs are generated. For the sake of efficiency and quality of services, the vehicle network and mobile communication will be utilized. The vehicle information including not only DTCs but other necessary data will be transmitted to the service center. The response time of GPRS, and the integrated system is measured in central Taiwan.
