The invention relates to a method for diagnosing a torque impulse generator. The torque impulse generator comprises a rotational input portion, a torque output portion, an oil reservoir and a torque generating arrangement (112) converting rotation of the input portion to torque impulses at the torque output portion. The method comprises: (301), detecting an acoustic signal (122) from the torque impulse generator while generating torque impulses, (302) extracting the frequency of torque impulses from the acoustic signal, and (303, 304) diagnosing the torque impulse generator based on the frequency of torque impulses, to indicate the level of oil in the oil reservoir. The invention further relates to a computer program product. 本发明涉及种用于诊断转矩脉冲发生器的方法。所述转矩脉冲发生器包括旋转输入部分、转矩输出部分、储油器和转矩发生装置(112)，所述转矩发生装置(112)将所述输入部分的旋转转化成所述转矩输出部分处的转矩脉冲。所述方法包括：(301)在产生转矩脉冲的同时检测来自所述转矩脉冲发生器的声学信号(122)；(302)从所述声学信号中提取转矩脉冲的频率；以及(303,304)根据转矩脉冲的频率来诊断所述转矩脉冲发生器从而指明所述储油器中的油水平。本发明还涉及执行所述方法的计算机程序产品。
