| | On Board Diagnostics - Wikipedia, the free encyclopedia |
 | | Modern OBD implementations use a standardized fast digital communications port to provide myriad realtime data in addition to a standardized series of diagnostic trouble codes, or DTCs, which allow one to rapidly identify and remedy malfunctions within the vehicle. |
 | | Unlike the OBD-I connector, which was sometimes found under the hood of the vehicle, the OBD-II connector is always located on the driver's side of the passenger compartment near the center console. |
 | | OBD scan tools can be categorized in two ways, based on whether they require a computer to operate (stand-alone vs PC-based), and the intended market (professional or hobby/consumer use). |
