3.4 Equipped vehicles

All petrol vehicles manufactured since 2000 and diesel vehicles manufactured since 2003 have been
equipped with OBD-II connection. Some older models have also got an OBD-II socket. You can get the
information from your specialist garage.
So that your vehicle is compliant with OBD-II, it must have a DLC (data link connector) with a 16-pin
connector under the dashboard and on the vehicle's emission control label it must be stated that the
vehicle is OBD-II-compliant.
