PROBLEM TO BE SOLVED: To provide, in a simple configuration and an inexpensive manner, a deterioration diagnostic system and a deterioration diagnostic method, capable of determining deterioration of an air conditioner mounted on a vehicle.SOLUTION: A deterioration diagnostic system comprises: an air conditioner AC which controls a temperature in a vehicle room; indoor temperature measuring means Ti for measuring data at an outdoor air temperature Te and an indoor temperature of a vehicle; indoor temperature predicting means PM for predicting an indoor temperature Ti from the outdoor air temperature Te; and deterioration determining means DM for determining the deterioration of the air conditioner AC on the basis of a difference ΔT between the indoor temperature Ti and a prediction temperature Tp obtained by the indoor temperature predicting means PM. The deterioration determining means DM determines the deterioration of the air conditioner AC on the basis of probability distribution of a prediction error ΔT obtained by subtracting the prediction temperature Tp from the indoor temperature Ti.SELECTED DRAWING: Figure 1
