Other vehicles

If your vehicle does not fall into any of the above categories, look under the hood and try to locate a label (Fig. 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 ElmScan 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 DLC that does not fully conform to SAE J1979. Compare figures 2 and 3, and notice the "ears" on the non-EOBD compliant Ford Focus.
