Sowing complexes perform several operations simultaneously, such as soil preparation and leveling, surface formation for sowing, sowing, seed rolling, and fertilizer application. Electronic control systems are used for efficient operation of sowing complexes. The method of diagnostics of electronic control system of modern sowing complexes is proposed in the article. The use of electronic systems allows us to automatically control the quality of sowing, adapt the work of the seeder to changes in movement parameters, and display the basic parameters of the system during operation, signal faults or non-compliance with agronomic requirements. To study the structure, principle of operation, settings and maintenance of the seeder, it is convenient to use training stands, the advantage of which is the compactness and convenience of the main elements of the electronic control system, and its use does not require significant time and resources, additional equipment and machinery. During the research, the characteristics and parameters of the sensor output signals for different operating modes were established. The principles of operation of the on-board network and data transmission technology of the main elements of the electronic control system of the drill are clarified. According of change oscillograms of information signals, the normative diagnostic parameters of the seeder sensors are set, which in the future will provide faster and more efficient diagnostics. Optical sensors have been found to use the UART data transmission protocol. One of the contacts of the seeding control sensor connector is the receiver (RX) and the other is the transmitter (TX) of the digital signal, which allows us to place a large number of sensors on one data line.
