 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 plug]]) using an OBD diagnostic device ([[OBD-Scanner]]). 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.
