The generation of vehicles fault due to man-made and environmental factors is irresistible. Auto detection diagnosis te
4、chnology in automotive technology is in a critical position, it puts forward higher requirements on automotive fault diagnosis. Motor fault diagnosis method are many, it had always give priority to with mechanic experience judgment, but with the development of the car, simply by experience of automo
5、bile maintenance already can not adapt to modern automotive technology requirements. For automotive professionals, using fault tree analysis, using statistical knowledge is a very simple and convenient diagnostic method. It can provide theoretical analysis basis for maintenance, and provide reference for improved design of automobile parts. Along with the development of the computer, in rapid and accurate diagnosis of the fault tree analysis was further improved. - II - Keywords ：f ault tree analysis; air-condition; diagnosis - III - 目录 序 言 . 1 第一章 空调故障诊断系统的软件介绍 2 1.1 课题任务分析
