It is a protocol for communicating with the onboard computer system in vehicles. It can be used for diagnostic purpose. I think that all new vehicles sold are required to support the OBD-II protocol. The OBD-II specification provides for a standardized hardware interface using a 16-pin J1962 connector. The latter connector is required to be within 2 feet (0.61 m) of the steering wheel with some exemptions. This allow for applications like using a smart-phone as an onboard dashboard car computer. However it should be noted that this site TOC will not allow for any discussion about using the ODB-II protocol. Then driving it is better to keep your eyes on the road, and not some app on your phone anywayhello all,
