Abstract

A system and method for evaluating and applying edits from one diagnostic tree to another matching or similar diagnostic tree is described. The system includes a diagnostic tree editor, a library, and a comparison engine. These elements work together to convert an OEM diagnostic tree to an optimized form for use in a repair shop environment by professional mechanics.

Claims

1. A system for modifying diagnostic trees comprising:

a model diagnostic tree including branches, each branch comprising vehicle information;

a diagnostic tree editor for modifying the model diagnostic tree to create an optimized tree template;

a subject tree to be evaluated, the subject tree including branches, each branch comprising vehicle information; and

a comparison engine for comparing each branch of the subject tree to a corresponding branch of the model diagnostic tree, wherein the comparison engine substitutes a matching branch from the optimized tree template for a corresponding branch in the subject tree, and flags a given branch in the subject tree for review if a corresponding given branch from the optimized tree template does not match.

2. The system of claim 1 further comprising a library for saving the optimized tree template.

3. The system of claim 1 wherein corresponding branches are located in the same position on the diagnostic tree and contain substantially similar vehicle information.

4. The system of claim 1 wherein an expert technician evaluates model diagnostic trees and flagged branches of diagnostic trees.

5. The system of claim 1 wherein a modified diagnostic tree is created when an expert technician accepts the flagged branches.

6. A method for modifying diagnostic trees comprising:

providing a model diagnostic tree for a class of vehicles, the model diagnostic tree including branches, the branches comprising vehicle information;

modifying the model diagnostic tree to include additional information;

storing the modified diagnostic tree in a library as an optimized tree template;

selecting a subject tree for modification via a comparison engine, the subject tree including branches, the branches comprising vehicle information;

comparing a branch of the subject tree to a corresponding branch of the model diagnostic tree;

if a match is found, substituting a matching corresponding branch from the optimized tree template in the subject tree; and

flagging the branch of the subject for review if no substitution is made.

7. The method of claim 6 wherein corresponding branches are located in the same position on the diagnostic trees and contain substantially similar vehicle information.

8. The method of claim 6 further comprising continuing the process until all branches of the subject tree have been evaluated.

9. The method of claim 6 further comprising storing the modified version of the subject tree as a provisional diagnostic tree in a memory.

10. The method of claim 9 further comprising notifying an expert technician that a provisional diagnostic tree is ready for review.

11. The method of claim 10 further comprising reviewing the flagged branches of the provisional diagnostic tree and accepting the changes and creating a complete modified diagnostic tree for further use in diagnostic devices and products.

12. The method of claim 10 further comprising reviewing the flagged branches of the provisional diagnostic tree and editing the flagged branches and creating a complete modified diagnostic tree for further use in diagnostic devices and products.

13. The method of claim 10 further comprising reviewing the flagged branches of the provisional diagnostic tree, rejecting the changes, and reverting back to the original branch from the subject tree.

14. The method of claim 11 further comprising selecting a procedure in the modified diagnostic tree, identifying an alternate procedure for obtaining substantially the same result as the procedure in the modified diagnostic tree, and storing the alternate procedure in the library.

15. The method of claim 14 further comprising replacing the procedure in the modified diagnostic tree with a matching alternate procedure.

16. The method of claim 12 further comprising selecting a procedure in the modified diagnostic tree, identifying an alternate procedure for obtaining substantially the same result as the procedure in the modified diagnostic tree, and storing the alternate procedure in the library.

17. The method of claim 16 further comprising replacing the procedure in the modified diagnostic tree with a matching alternate procedure.

18. The method of claim 12 further comprising selecting a procedure in the modified diagnostic tree, identifying an alternate procedure for obtaining substantially the same result as the procedure in the modified diagnostic tree, and storing the alternate procedure in the library.

19. The method of claim 18 further comprising replacing the procedure in the modified diagnostic tree with a matching alternate procedure.

20. A method for modifying diagnostic trees comprising:

providing a model diagnostic tree for a class of vehicles, the model diagnostic tree including branches, the branches including nodes;

modifying the diagnostic tree to include additional information;

storing the modified diagnostic tree in a library as an optimized tree template;

selecting a subject tree for modification via a comparison engine, the subject tree including branches, the branches comprising nodes;

comparing a node of the subject tree to a corresponding node of the model diagnostic tree;

if a match is found, substituting a matching corresponding node from the optimized tree template in the subject tree; and

flagging the node of the subject for review if no substitution is made.
