An IVHM Reference Model contains relations between Symptoms, Failure Modes, Troubleshooting Tests and Corrective Actions. Since it also encodes the specific vehicle variants for which these items are applicable, it can be used to create vehicle variant specific fault isolation plans for a pattern of symptoms on a specific vehicle. This paper will discuss the methodology through which a diagnostic reasoner can use a fault model, vehicle reported symptoms and vehicle configuration data to produce a vehicle fault specific troubleshooting plan. This paper will also discuss how a wide variety of Diagnostic Work Plans can be automatically created for a platform and its variants and how these plans can be adapted by Service Engineering authors to further improve their content.
