Onboard-diagnostic (OBD) system is developed to detect engine operation conditions for air-pollution monitoring. The diagnostic trouble code from vehicle microprocessor is generated resulting from a system error or malfunction. Based on a practical demand, this paper presents a modified system construction from vehicle surveillance technology for OBD data report in real time. A circuit system is designed and fabricated to convert OBD protocol into RS-232 protocol for data transmission via general-packet-radio-service mobile communication. The proposed system integrates the developing technology for both OBD and intelligent-transportation-system applications. In this paper, hardware and software in both design and implementation are discussed and verified by road tests.
