Abstract
A diagnostic expert system is set up with a first diagnostic subsystem based on a maintenance technician's knowledge and a second diagnostic subsystem based on a design engineer's knowledge. If a fault cannot be located under the first diagnostic subsystem, the second diagnostic subsystem, which operates by using the result obtained from the first diagnostic subsystem is started so as to determine the location of the fault.
