-An OBD system consists of at least one control unit that uses measured values from various sensors (e.g. oxygen sensors) to control actuators (e.g. injection nozzles) to achieve the desired behaviour. A modern vehicle can contain countless ECUs, each supporting hundreds of parameters that can be accessed via the DLC (Diagnostic Link Connector, [[obd-2-buchse]] ) using an OBD diagnostic device.

-Apps are available for mobile devices that display real-time data from the respective ECUs (virtual instrument panel). One example is the OBD app Drivedeck. For Microsoft Windows, for example, there is the OBD-2 software KOBD2Check and [[vcds]] for manufacturer-specific OBD on Audi, Seat, Skoda and VW. An OBD diagnostic device with its own display, which is independent of basic devices such as mobile phones, PCs or laptops, is practical for [[diagnose]] everyday use in the workshop.
