PCT No. PCT/DE90/00481 Sec. 371 Date Feb. 6, 1992 Sec. 102(e) Date Feb. 6, 1992 PCT Filed Jun. 26, 1990 PCT Pub. No. WO91/02257 PCT Pub. Date Feb. 21, 1991.The device for monitoring functions of control devices of a motor vehicle includes a single monitoring indicator; monitoring signal devices in each control device which generate a monitoring signal characteristic of their operation; a driver stage for controlling the single monitoring indicator located in a central control device; a device for controlling the monitoring signal devices so that monitoring signals are produced, advantageously one after the other, in response to a switch-on signal; a device for producing the switch-on signal such as an ignition device, and at least one line to which each control device is connected so that, when the monitoring signal is produced, the monitoring signal thus produced is transmitted to the central control device including the driver stage and the driver stage controls the single monitoring indicator according to the monitoring signal so produced. In preferred embodiments the duration and/or signal interval of the monitoring signal is characteristic of the control device from which it originates.
