All cars and light trucks built and sold in the United States after January 1, 1996 were required to be OBD-II equipped. In general, this means all 1996 model year cars and light trucks are compliant, even if built in late 1995. Some 1995 model year vehicles are also equipped with OBDII – although some pre-1996 OBD-II cars are not 100% compliant. Pre-OBD-II cars had connectors in various positions under the dashboard and under the hood. All OBD-II cars have a connector located in the passenger compartment easily accessible from the driver’s seat.
