A method for diagnosing a torque impulse generator which includes a rotational input portion, a torque output portion, an oil reservoir and a torque generating arrangement converting rotation of the input portion to torque impulses at the torque output portion, the method includes: detecting an acoustic signal from the torque impulse generator while generating torque impulses, extracting the frequency of torque impulses from the acoustic signal, and diagnosing the torque impulse generator based on the frequency of torque impulses, to indicate the level of oil in the oil reservoir.
