The paper describes standard methods of diagnosing of the AMV (the Rosomak) drive unit technical condition used in daily operation in military missions in Afghanistan. Main rule of the method of diagnosing of the vehicle technical condition is using an external diagnosing system. This system is connected to the vehicle at the time of checking of operation of the powertrain control system configuration of the drive unit to permit the diagnosis, including examination of the engine and gearbox. Enhanced diagnostic system is connected to the OBD system with using standard PC computer with appropriate software. Stored examples of the results of the operation of such system are included in the paper. Measuring was led on a dynamometer stand to perform research of a propulsion unit in work condition. Measurements of the engine parameters were led in steady state and transient engine operating conditions. Unsteady-state condition studies were carried out using the method of free-range acceleration of the engine. Pointed out the merits of the development of this type of study due to the perceived potential and usefulness of the results obtained. The results of studies carried out by various methods and assess the current condition of the engine and the entire powertrain were compared.
