Technical solutions are described for lash detection diagnostic in a steering system. An example method includes sending, by a controller, an excitation motor command to a motor control system. The method further includes measuring, by the controller, a sensor signal generated in response to the excitation motor command. The method further includes determining, by the controller, a decay rate of a change in magnitude of the signal at a plurality of frequencies. The method further includes diagnosing, by the controller, that the steering system has a lash condition based on the decay rate exceeding a predetermined threshold.
