The disclosure relates to a method for checking a steer-by-wire steering system that includes a steering device, a steering wheel, an actuator configured to exert a torque on the steering wheel, and a control unit configured to correlate a steering wheel angle of the steering wheel with a steering angle of the steering device The method comprises the following steps: i) the actuator is controlled in a closed-loop manner such that the steering wheel angle is correlated with a desired angle and a temporal progression of a state variable of the steering wheel and/or of the actuator is determined; ii) a frequency spectrum of the temporal progression of the state variable is determined and an amplitude of a predefined spectral component of the frequency spectrum is determined; and, iii) a state of the mechanical coupling is classified depending on the amplitude of the spectral component.
