In a classical approach to damage diagnosis, the technical condition of an analyzed machine is identified based on the measured symptoms, such as performance, thermal state or vibration parameters. In wheeled tractor the fundamental importance has monitoring and diagnostics during exploitation concerning technical inspection and fault element localizations. The main functions of a diagnostic system are: monitoring tractor components which affect operation, safety, performance parameters and exhaust gas emissions; registering information about component damage; registering performance parameters at the moment of damage. The diagnostic device detects and identifies the following types of defects: functional defects (uf) which affect performance, exhaust defects (ue) which increase toxic emissions and fuel consumption, defects that jeopardize driving safety (us), defects that affect engine performance (ud). The key component of diagnostic device is on-board computer with touch screen, connected by USB/DeviceNet converter (master module) via the USB port. The CAN bus connects the interface module with one (three) slave modules collecting data from sensors installed in various locations of wheeled tractor. Slave devices acts as data concentrator units. In the paper hardware structure, developed software, basic algorithms of diagnostic system and some realized tests of a wheeled tractor are presented.
