A trouble diagnosing device for diagnosing a fault in a control circuit for controlling a plurality of electromagnetic actuators in an operating system such as a brake system. The control circuit receives a plurality of mutually independent input signals for individually controlling the operations of the electromagnetic actuators. The trouble diagnosing device includes an analog signal oscillator for feeding a trouble diagnosing analog signal to the control circuit and a trouble diagnosing circuit receiving the output signals from the control circuit for producing output signals indicating fault in the control circuit when the output signals of the control circuit include an abnormal signal.
