- An object of the paper is development process of on-board systems diagnostic which can be divided into the historic phase (defined as OBD I), the present term - OBD II and OBD III, and the destination regulation. Established OBD II requirements use allowable the driving emission level limits of the FTP test, however its European EOBD equivalent, effective in Poland, uses limits (together with suitable coefficients of the enlargement) in the NEDC (New European Driving Cycle) test. The research programme of homologation is based on standard driving cycles of characteristic courses of the speed. Conditions of the realization of procedures are selected, so that their meeting in driving cycle is confident and so that its realization secures the correct result. Results of the procedure are illustrated with the original coefficient of the cover of the cycle time by found similar fragments driving cycles. In particular inter alia main criteria of damages according to Californians' CARB OBD II regulations, vehicle performance record during FTP75 test on chassis dynamometer, implementation of oxygen sensor monitor marked with vertical line, RPM, engine loading, engine temperature, speed, NEDC (UDC + EUDC) driving test, temperature chamber and chassis dynamometer stand control devices, dilution exhaust gases device, exhaust gases analyzers are presented in the paper.
