What cars have OBD-II?

All cars and light trucks sold in the United States after January 1, 1996 are required to have OBD-II. In Europe, OBD-II (called EOBD) became mandatory for gasoline cars in 2001 and diesel cars in 2003. In practice, some 1994-1995 model year vehicles also have partial OBD-II compliance. You can verify by checking for the standard 16-pin trapezoidal DLC connector, typically located under the dashboard on the driver's side.
