===ADR 79/01 & 79/02 (Australian OBD standard)===

The ADR 79/01 Vehicle Standard ('''A'''ustralian '''D'''esign '''R'''ule '''79/01''' – Emission Control for Light Vehicles, 2005) is the Australian equivalent of OBD-II. It applies to all vehicles of category M1 and N1 with a Gross Vehicle Weight rating of {{cvt|3500|kg|lb}} or less, registered from new within Australia and produced since January 1, 2006 for [[petrol]]-engined cars and since January 1, 2007 for [[Diesel fuel|diesel]]-engined cars.<ref>{{cite web |url=http://www.comlaw.gov.au/Details/F2008C00323|title=Vehicle Standard (Australian Design Rule 79/01 – Emission Control for Light Vehicles) 2005|date=April 28, 2007 |publisher=Australian Government ComLaw}}</ref>

For newly introduced models, the regulation dates applied a year earlier – January 1, 2005 for petrol and January 1, 2006, for diesel. The ADR 79/01 standard was supplemented by the ADR 79/02 standard which imposed tighter emissions restrictions, applicable to all vehicles of class M1 and N1 with a Gross Vehicle Weight rating of 3500&nbsp;kg or less, from July 1, 2008, for new models, July 1, 2010, for all models.<ref>{{cite web |url=http://www.comlaw.gov.au/Details/F2010C00476|title=Vehicle Standard (Australian Design Rule 79/02 – Emission Control for Light Vehicles) 2005|date=June 30, 2010 |publisher=Australian Government ComLaw}}</ref>

The technical implementation of this standard is essentially the same as OBD-II, with the same SAE J1962 diagnostic link connector and signal protocols being used.
