This article will help you determine if you can use OBDLink® adapters with your vehicle.

OBD-II compatibility is related to where your vehicle was purchased when new, not where the vehicle was manufactured.

Vehicles sold in the United States

All vehicles sold in the United States in 1996 or later are compatible with OBD-II. 

United States legislation requires all cars and light trucks model year (MY) 1996 and newer to be OBD-II compliant. More information is available on the EPA's website. Our OBDLink adapters work on all 1996 and newer cars and light trucks sold in the United States, including: 

Note: Hybrid and Electric vehicles are low or zero emission vehicles, however, OBDLink adapters may not work. Check your vehicle manual, research online, or consult with your dealership.

Vehicles sold outside the United States

OBD-II compliant vehicles

To read the chart below, choose the country where your vehicle was sold new to see if it is OBD-II compliant.

2001 or newer model year gasoline vehicles sold in the European Union

Commission Directive 70/220/EEC, Annex I:

8.1. Vehicles with positive-ignition engines

With effect from 1 January 2000 for new types and from 1 January 2001 for all types, vehicles of category M1, except vehicles the maximum mass of which exceeds 2500 kg, and vehicles of category N1 class I, must be fitted with an on-board diagnostic (OBD) system for emission control in accordance with Annex XI. [...]

Note that here "European Union" means countries that were members of the EU in 2000.

2004 or newer model year diesel vehicles sold in the European Union

Commission Directive 70/220/EEC, Annex I:

8.2. Vehicles with compression-ignition engines

Vehicles of category M1, except
- vehicles designed to carry more than six occupants including the driver,
- vehicles whose maximum mass exceeds 2500 kg,
from 1 January 2003 for new types and from 1 January 2004 for all types, must be fitted with an on-board diagnostic (OBD) system for emission control in accordance with Annex XI.

Note that here "European Union" means countries that were members of the EU in 2003.

Other vehicles

If your vehicle does not fall into any of the above categories, look under the hood and try to locate a label (Figure 1) that explicitly states that the vehicle was designed to comply with OBD-II legislation.

In this case, OBD-II is used as a general term and can mean any of the following:

• OBD II (California ARB)
• EOBD (European OBD)
• JOBD (Japanese OBD)

You may also consult your vehicle's owner's manual and perhaps contact your local dealer. However, be aware of the fact that many dealers do not know the difference between OBD and OBD-II.

If the vehicle is not OBD-II compliant, you cannot use a generic OBD-II scan tool such as OBDLink adapters to obtain diagnostic information from your vehicle.

But my car has the 16-pin OBD connector, shouldn't it be OBD-II compliant?

No, not necessarily. A lot of European and Asian manufacturers equipped their vehicles with D-shaped 16-pin connectors long before they began installing OBD-II systems on those vehicles. One curious thing to note here is the fact that most non-EOBD compliant vehicles had a Data Link Connector (DLC) that does not fully conform to SAE J1979. Figure 2 shows the correct DLC type.
