ABSTRACT:
The present invention, in one embodiment, is a method for identifying highly suspect components in fault isolation. The method for identifying highly suspect components of a system wherein faulty operation has been indicated, respective components of the system generating respective error codes upon occurrence of faulty operation, includes the steps of identifying loops/strings of components, each loop/string being composed of at least one component which generated an error code, determining whether any of the loops/strings have common components, and identifying any of the common components as highly suspect components.
