Conversion of static diagnostic procedure to dynamic test plan method and apparatus
First Claim
1. A computer-implemented method of converting a tree-graph representation of a diagnostic procedure into a dynamic decision sequencing representation based on a plurality of elementary diagnostic tests for use with a diagnostic plan generator, the method comprising:
- reading a tree-graph that represents the diagnostic procedure;
identifying an end node of the tree graph;
associating the end node with a failure mode; and
tracing a path through one or more intermediate nodes to a root node.

Abstract
A diagnostic information converter reads an existing static diagnostic procedure in the form of a tree graph and generates a diagnostic Failure Modes and Effects Analysis that can be used in the generation of a dynamic diagnostic test plan. The converter identifies the end nodes of the graph and associates a specific failure mode with each of the end nodes. In addition, the converter traces a unique path from each end node along successive branches through one or more intermediate nodes to the root node, and from each of the paths derives an initial failure mode test including the test steps corresponding to the root node, the intermediate nodes and the end node. The converter further identifies and annotates precondition nodes that correspond to a vehicle state or condition, rather than to an actual diagnostic test step and allows a user to edit the initial failure mode tests.
