+Vehicle diagnostic protocol for monitoring the emission-related systems of a motor vehicle. Also called OBD-II. EOBD is the European counterpart to OBD-2 (OBD-II). Of particular importance here are exhaust gas recirculation ([[EGR]]), catalytic cleaning ([[catalytic converter]]) with the aid of the [[lambda]] probe and installed particulate filters (e.g. [[DPF]]).
 OBD-2 uses a 16-pin connector to connect a diagnostic system to the vehicle. Although the presence of this connector is mandatory for OBD-2 compatibility, it is not possible to infer an implemented OBD-2 protocol from the connector.
-All passenger cars from 2008 onwards and all motorbikes from 2017 onwards (exhaust emission standard EU4, EU5 and newer) use [[en:can]] with ISO15765 protocol for OBD-2 diagnosis. Earlier vehicles mostly use [[k-line]] , more rarely VPW or PWM.

 Many manufacturers use the [[obd-2-plug]] in the vehicle (also) for the manufacturer's own OBD. OBD-2 protocol and manufacturer's own diagnostics do not necessarily have to use the same physical connection. A 2006 VW Golf, for example, uses CAN Bus for the manufacturer's own diagnostics but K-Line for OBD-2.

 It is important to know that the OBD-2 diagnostic protocol does not offer the diagnostic depth of the manufacturer's own diagnostics. If possible, diagnostic software that supports the diagnostic protocols of the respective vehicle manufacturer should be used.
