Abstract
A reverse failure analyzer determines a group of diagnostic test procedures related to a particular vehicle component from a pool of diagnostic procedures, and then identifies the specific failure modes of each of the diagnostic test procedures. The reverse failure analyzer further associates the specific failure modes with the respective vehicle component associated with each of the diagnostic test procedures, and the symptoms associated with each of the diagnostic test procedures to the correlated vehicle components and failure modes. In addition, the reverse failure analyzer can cross-reference various vehicle components that can be the root cause of a particular symptom or a vehicle operational problem. Furthermore, the reverse failure analyzer can receive observed symptoms regarding a particular test subject vehicle and correlate the observed symptoms to the vehicle components that can cause the symptoms based on the results of reverse failure analyses.
