Abstract
The purpose of the study is to carry out the experimental tests for the propulsion unit of the selected passenger car i.e. Skoda Felicia 1.3 MPI provided with Simos 2P system (manufactured by Siemens). The tests were carried out by means of an appropriate measuring equipment, among others AOC1K oscilloscope (digital recorder integrated with PC by means of RS232 interface) and a personal computer. The measurements of signals on the contacts of the electronic control device encompass the measuring procedures for individual signals, in accordance with the contact symbols: the camshaft position sensor, the engine speed sensor, the lambda probe, the pressure sensor, the throttle position sensor, the idle speed control actuator, the knock sensor. In some cases it is impossible to confirm the standard codes by the execution of diagnostic tests of the modern control system of ZI combustion engine, using the Simos 2P system.

Summary
The use of the achievements in the scope of electronics, automatic control engineering and information technology appear to be an essential step in the automotive sector development stimulating the analyses of environment protection requirements, improving the road traffic safety and increasing the comfort of travel. In order to meet the requirements in the scope of modern equipment of the vehicles, it is necessary to promptly analyse the occurred situation (within a part of second), to elaborate the conclusions and to ensure the correct reaction, sometimes even against the actions performed by the driver, in case of safety systems i.e. ABS, ESP increasing the level of safety on crowded roads which are not adapted to the design solutions of modern vehicles. Wymagania dotyczące współczesnego wyposażenia pojazdów wymuszają konieczność błyskawicznej analizy zaistniałej sytuacji, wypracowania wniosków i odpowiedniego zareagowania, niejednokrotnie wbrew czynnościom wykonywanym przez kierowcę. Wymagania dotyczące przesyłu informacji we współczesnych pojazdach wymusiły wprowadzenie innego rodzaju okablowania sieci pokładowych – instalacje multipleksowe, wykorzystujące między innymi światłowody. Sometimes it is impossible to confirm the conformity with the standard codes by the execution of diagnostic tests of the modern control system of ZI combustion engine, using the Simos 2P system (manufactured by Siemens)
