The vehicle real-time running status monitoring and on-board diagnostic system is designed to meet the need of diagnosing vehicle for private cars owners. The functions, such as the real-time data flow reading and recording, on-board diagnostic, voice reminding, displaying error code and corresponding content with liq-uid crystal displayer, data transferring via universal serial bus, are provided by this system. Furthermore, owner-drivers are able to know the running status of the vehicles, monitor whether their cars are in good condition, and then to locate malfunctioning parts via KWP1281/ISO9141/ISO14230(KWP20OO)/SAE J1850 VPW/SAE J1850 PWM/ISO15765 protocols to ensure safe driving and reduce the cost of maintenance.
