A STUDY AND ANALYSIS OF THE ON BOARD DIAGNOSTIC SYSTEM (OBD) ON LIGHT DUTY VEHICLES

This report describes the technical level in general terms of an On Board Diagnostic system (OBD) and the practical results during simulated faults. As the test results indicated this OBD system fulfills the criteria set up by the regulations, and the results also indicates the benefit of such systems in order to improve the air quality. During the test period it has been shown that the OBD system is necessary for the workshops and the annual vehicle inspection to receive a fast and correct judgement about the condition of the vehicles' emission control system. This is especially important since today's emission control systems already are complicated, and the future development in this area will give us even more technically advanced systems. The warnings from the OBD system also will have the potential of saving money and trouble for the car owner and manufacturer. Early warnings will limit the risk of destroying vital engine or emission control components. (A)
