OBD2 (On-Board Diagnostic II)

Abstract

In this work, we create a framework to efficiently connect and acquire data from commercial automobiles. A system that proficiently monitors and administers the vehicles operating parameters and its performance is difficult to design and realize. We design a circuit to achieve connectivity for vehicles equipped with an on-board diagnostics computer–second generation (OBD-II) computer. The engine control unit (ECU) is accessed and the data is processed for diagnostics and analysis by using STN1110 mediator integrated circuit. The Bluetooth interface is used to provide connectivity to the OBD-II computer and the users monitor and operate the system through a mobile phone application. An efficient interface is provided to troubleshoot engine errors, emission errors and other automobile system errors.
