1. OBD1 is connected to the console of a car, while OBD2 is remotely connected to the vehicle. 2. OBD1 was used during the earlier years of the car manufacturing industry, while OBD2 was only introduced in car models produced in the early 1990's.
Subsequently, question is, how do I know if my vehicle is OBD2 compliant? 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. 2) There will be a note on a sticker or nameplate under the hood: "OBD II compliant".
