On-Board Diagnostics

On-Board Diagnostics or OBD, was the name given to the early emission control and engine-management systems introduced in cars. OBD systems have been developed and enhanced in line with US government requirements into the current OBD2 standard which applies to all cars sold in the US from 1996.  EOBD2 is the European equivalent of the American standard and applies to gasoline/petrol cars sold in Europe from 2001 (and diesel cars three years later). This course is about OBD monitors, scanners, and ECU fuel trim diagnostics.
