Abstract

This paper presents the development of a generic OBD device and its working with different vehicles based on OBD-TT standards like Land Rover Defender. This device shows the real time vehicle system status, including vehicle speed, engine RPM, throttle position, battery voltage, engine coolant temperature etc. and the diagnostic trouble codes (DTCs) for different vehicles. The software has also been indigenously developed which is used as interface between user and the ECU of the vehicle. This device helps the user to understand the vehicle status and check malfunctions by indicating the Diagnostic Trouble Codes (DTCs). This generic device can prove as an easy to use, battery free device that drives power from the vehicle battery and is easily connected to the PC using USB port.
