Abstract : The main aim of this paper is to implement (Society of Automotive electronics) SAE J1939 protocol standard which is a CAN based communication, for one of control units in the vehicle called Instrument Cluster, which acts as a gateway between driver and vehicle ECUs. In networking ECUs in heavy duty vehicles, it is J1939 protocol plays a key role. J1939 addresses inter ECU communication and Diagnostics of individual ECUs. This paper addresses Diagnostics part of the protocol layer along with other low level layers like Transport and Network. Part of the data link layer by default is taken care by CAN protocol alone and rest as specified in J1939 standard. SAE International has more than 121,000 members - engineers, business executives, educators, and students from more than 97 countries - who share information and exchange ideas for advancing the engineering of mobility systems. Our paper mainly concerned with design preparation, programming the microcontroller, interfacing the microcontroller and the hardware, final integration and testing of the complete system.
