What does an OBD II scanner do?
Onboard Diagnostics II (OBD-II) is a standardized system that onboard computers in cars and trucks use for self-diagnostics and reporting. Unlike earlier, OEM-specific OBD-I systems, OBD-II systems use the same communication protocols, code designations, and connectors from one manufacturer to another.
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".
