Self Study Program 231 – Euro On-Board Diagnostic System For petrol engines

Self Study Program 231 – Euro On-Board Diagnostic System For petrol engines Design and Function PDF free online

Now an integral part of emission control and monitoring in the USA, the On-Board Diagnostics (OBD II) system will also be introduced within the European Union under the name Euro-On-Board Diagnostics (EOBD) from 1st January, 2000. Initially, the system will be available for petrol engines only, however, a version for diesel engines will follow in the
foreseeable future.

There are very few differences between European variant of this diagnostic system and
US OBD II.

The only alterations made were those necessary to bring EOBD into line with European exhaust emission legislation. Other noteworthy features of EOBD are its central diagnosis interface and self-diagnosis fault warning lamp.

In this Self-Study Programme, we will show you new monitored vehicle systems and the
associated diagnostics, taking Self-Study Programme 175 “On-Board Diagnostics II in the
New Beetle (USA)” as the basis. In this way, you will not have to read through repetitive material.
