With the development of the technology, modern automobiles now are all equipped with an On-board Diagnostics system (OBD). There are two kinds of OBD. One is OBD-I, the other is OBD-II. As you can guess OBD2 codes is an improvement over OBD-I in both capability and standardization. It is an advanced management system that professionals and backyard mechanics can connect to via the diagnostic port. You can also use a computer or laptop instead of a handheld scanner; however, you will need a kit. Most laptop diagnostic software is more advanced than handheld scanners, offering the ability to monitor check engine performance, as well as read trouble codes.
