Study on Diagnosis of Automotive Network

Modern Automobiles uses embedded technology wherein the devices like Engine, Ignition Systems, Gauges, Sensors, Actuators etc. are controlled by ECU (Engine Control Unit). As ECUs control multiple devices the network becomes complex. Due to the complexity it is difficult to identify where the fault is occurred. In order to identify the fault and diagnose the same certain diagnostic protocols are made use. This paper enlightens about these protocols and their results that are studied from various researchs.
