A method for troubleshooting an underwater acoustic transducer array comprising a plurality of transducers so as to test the operationally installed underwater transducer array on board for its operational reliability and to be able to localize malfunctioning transducers. For this purpose, a sinusoidal test signal, preferably the transmitted signal itself, is fed through a connecting line into the transducer array from a location remote from the transducer array and the current flowing through the transducers is detected by at least two samplings as the real component and the imaginary component with respect to the test signal. The sampling values are transmitted back to the remote location and the admittance of each transducer is determined from the ratio of the real component and of the imaginary component of the current to the test signal amplitude. A significant deviation from the known admittance at the test signal frequency is interpreted as a transducer malfunction.
