What cars have OBD-II?
Quick Answer
Compatibility depends on market, model year, vehicle class and manufacturer information; the connector alone is insufficient proof.
In the United States, most model-year 1996 and later passenger cars and light-duty vehicles use OBD-II. Other markets introduced related requirements on different schedules, with exceptions by vehicle class, fuel and approval date. Some earlier vehicles also support OBD-II. Confirm the emissions label, owner manual and manufacturer service information for the exact vehicle. A 16-pin connector alone does not prove complete compatibility.
