    Modern motor vehicles are equipped with a variety of electronic control systems connected into networks and communicating using various different communication protocols. For the purpose of this thesis we studied the functioning of the most commonly used protocol, the Controller Area Network (CAN). We also studied the On Board Diagnostics standard (OBD), which is used for diagnostics of these control systems. We have designed and built an affordable tool, which enables diagnostics by sending requests adhering to the OBD-II standard to the CAN network. The tool consists of two different (ARM, AVR) microcontrollers, a CAN transceiver and an LCD display. We have also designed software for the tool, which lets the user choose and display different diagnostic parameters. The software also supports traffic monitoring on the CAN network. In the end we have provided suggestions on how to improve the functioning of the tool.
