Abstract

A method and system for optimizing vehicle diagnostic trees using similar templates is provided. Diagnostic trees may be modified to include diagnostic code tips or further suggestions or instructions indicating what tool to use or how to use the tool. The diagnostic tree cab be modified or customized by comparing the diagnostic tree to previously modified diagnostic trees corresponding to similar vehicles, and suggestions within the previously modified tree that are referenced within a library can be linked to the diagnostic trees.

Claims

1. A method of providing enhanced fault diagnostics, said method comprising the steps of:

providing a diagnostic information portal;

storing an Original Equipment Manufacturer diagnostic tree at said diagnostic information portal;

operatively coupling a diagnostic tool and said diagnostic information portal;

operatively coupling computerized equipment and said diagnostic tool;

formulating a request by said diagnostic tool;

directing said request to said diagnostic information portal, said request seeking diagnostic information related to said computerized equipment;

providing diagnostic information by way of said diagnostic portal in response to said request; and

collecting fault diagnostic information related to said computerized equipment based on said diagnostic information,

said diagnostic information being in a form of a diagnostic tree, said diagnostic tree comprising at least one node and at least one branch.

2. The method of claim 1 further comprising the step of

formulating said request based on information received from said computerized equipment.

3. The method of claim 1 further comprising the step of

formulating said request based on information received from said computerized equipment and a diagnostic information source.

4. The method of claim 1 where said diagnostic tree comprises an Original Equipment Manufacturer (OEM) diagnostic tree.

5. The method of claim 1 further comprising the step of

utilizing said diagnostic tree to diagnose a fault experienced by said computerized equipment.

6. The method of claim 1 further comprising the step of

automatically collecting diagnostic information from said computerized equipment.

7. The method of claim 1 further comprising the step of

collecting fault diagnostic information from said computerized equipment upon a user command.

8. The method of claim 1 further comprising the step of

operatively coupling a diagnostic information store to said diagnostic information portal, said diagnostic store providing diagnostic information related to said computerized equipment.

9. The method of claim 8 further comprising the step of

utilizing a data network to operative couple said data network to said diagnostic information portal.

10. The method of claim 1 wherein a vehicle utilizes said computerized equipment.

11. The method of claim 1 wherein a machine utilizes said computerized equipment.

12. The method of claim 1 wherein diagnostic equipment utilizes said computerized equipment.

13. A method for analyzing an Original Equipment Manufacturer (OEM) diagnostic tree, said method comprising the steps of:

providing a first OEM diagnostic tree having a first branch, said first branch comprising code information;

editing said first OEM diagnostic tree;

creating a first edited OEM diagnostic tree;

providing a new diagnostic tree, said new diagnostic tree having a first branch, said first branch of said new diagnostic tree comprising code information; and

comparing said code information of said first revised OEM diagnostic tree and said code information of said new diagnostic tree;

substituting said code information of said new diagnostic tree with said code information of said revised OEM diagnostic tree.

14. The method of claim 13 where said diagnostic tree is utilized by a diagnostic tool to diagnose a fault experienced by a computerized system.

15. The method of claim 14 wherein said computerized system resides in a vehicle.

16. The method of claim 14 wherein said computerized system resides in a machine.

17. The method of claim 14 wherein said computerized system resides in diagnostic equipment.

18. A method comprising:

receiving a first diagnostic tree including a first set of procedures for diagnosing causes of faults which can be experienced by a first apparatus under diagnosis and suggestions for performing said first set of procedures on said first apparatus, wherein each procedure in said first set of procedures may include a corresponding suggestion, and wherein each procedure in said first set of procedures includes an identifier;

receiving a second diagnostic tree including a second set of procedures for diagnosing causes of faults which can be experienced by a second apparatus under diagnosis, wherein each procedure in said second set of procedures includes an identifier;

identifying matching identifiers within said first set of procedures and said second set of procedures so as to identify similar procedures; and

for each similar procedure, identifying a corresponding suggestion for performing said procedure on the first apparatus.

19. The method of claim 18 further comprising the step of modifying said second set of procedures within said second diagnostic tree so as to associate suggestions for performing a procedure on said first apparatus to similar procedures within said second set of procedures.

20. The method of claim 19, wherein modifying said second set of procedures within said second diagnostic tree comprises copying suggestions from said first set of procedures to said second set of procedures.

21. The method of claim 18, wherein identifying matching identifiers within said first set of procedures and said second set of procedures so as to identify similar procedures comprises matching information relating to faults which can be experienced by said first apparatus and said second apparatus.

22. The method of claim 18, wherein said identifier is a vehicle identifier, and wherein identifying matching identifiers within said first set of procedures and said second set of procedures so as to identify similar procedures comprises matching vehicle identifiers.

23. The method of claim 18, wherein said identifier is a vehicle identifier, and wherein identifying matching identifiers within said first set of procedures and said second set of procedures so as to identify similar procedures comprises determining whether identifiers within said second set of procedures belong to said same class of vehicles as do identifiers within said first set of procedures.
