A system for diagnosing electronic control systems mounted in a motor vehicle has a signal receiver for receiving a data demand signal from a diagnosis device, an interpreter for interpreting a content of the received data demand signal and a signal transmitter for transmitting an output signal to the diagnosis device in accordance with the interpretation. A signal receiving line connects all of the signal receivers with each other in parallel, and a signal transmitting line connects all of the signal transmitters with each other in parallel. The signal receiving line and signal transmitting line are connected with the diagnosis device by a connector.
