In order to meet market needs, air conditioning devices have been installed in recent years, but the engine has not been improved. After installing an air conditioner, the power dissipation increases, resulting in insufficient power of the original engine and poor air conditioning effect. The air conditioner clutch repeatedly engages, which is easily burned out. Therefore, by using the sound of the air conditioner engagement, the fault location can be quickly identified.
