Abstract

A method of processing system diagnostic data is provided for identifying likely device fix(s) associated with a diagnostic data, and identifying a repair procedure(s) for correcting the likely fix(s). The process receiving diagnostic data from a system onboard computer at a remote diagnostic database, the database being arranged to map system diagnostic data to possible vehicle fix(s). The possible device fix(s) are prioritized in accordance with ranked matches of the received diagnostic data to combinations of diagnostic data stored in a prior experience database. The prior experience database having an identified fix associated with each stored combination of diagnostic data. The fix associated with the highest ranked combination of diagnostic data is identified as the most likely fix. The most likely fix is mapped to a system repair database, the most likely fix being directly mapped to an associated repair procedure for repairing the most likely fix.

Claims

1. A method of processing diagnostic data from a defective home electronic device to identify the most likely fix associated with the diagnostic data, the process comprising:

receiving at a hand held scan tool a combined set of diagnostic data downloaded from an electronic control unit disposed within the device; and

prioritizing possible fix(s) in accordance with ranked matching of the downloaded combined set of diagnostic data to combined sets of diagnostic data stored in a prior experience database, the prior experience database having at least one possible fix associated with each combined set of stored diagnostic data, the fix possible associated with the highest ranked set of stored diagnostic data being identified as the most likely fix.

2. The process as recited in claim 1 wherein the step of prioritizing the possible fix(s) further comprises the step of identifying the stored set of diagnostic trouble codes having the greatest number of the diagnostic trouble codes that correspond to the set of diagnostic trouble codes downloaded from the device electronic control unit, and identifying the stored set of diagnostic trouble codes having the least number of diagnostic trouble codes that do not correspond to the set of diagnostic trouble codes downloaded from the system computer.

3. The process as recited in claim 2 wherein the step of prioritizing possible fix(s) further comprises the step of identifying the stored set of diagnostic trouble codes having the highest successful fix count associated therewith.

4. The process as recited in claim 3 wherein the step of prioritizing possible fix(s) further comprises the step of prioritizing the stored set of diagnostic trouble codes having the lowest cost of repair associated therewith.

5. The process as recited in claim 1 further comprising the steps of:

i. accessing repair procedures database for repairing a range of defective conditions;

ii. linking the most likely fix(s) to a selected repair procedure(s) in the repair procedures database, the selected repair procedure(s) being effective to implement the most likely fix(s); and

iii. accessing the selected repair procedure(s) effective to implement the most likely fix(s).

6. The process as recited in claim 1 further comprising the step of communicating the downloaded set of diagnostic data from a hand held scan tool to a personal computer and then communicating the downloaded set of diagnostic data from the personal computer to the remote diagnostic database for prioritizing possible fix(s).

7. The process as set forth in claim 5 comprising the step of communicating information concerning the most likely fix(s) and the associated repair procedure to the scan tool.

8. The process as recited in claim 1 further comprising the steps of:

communicating the downloaded set of diagnostic data from the scan tool to a personal computer; and

communicating the downloaded set of diagnostic data from the personal computer to the remote database.

9. The process as recited in claim 8 wherein the step of communicating the downloaded set of diagnostic data from the scan tool to personal computer comprises wirelessly communicating the downloaded set of diagnostic data from the scan tool to the personal computer.

10. The process as recited in claim 1 wherein the diagnostic data is wirelessly downloaded from the home electronic device to the scan tool.

11. The process as recited in claim 1 further comprising the steps of:

wirelessly communicating the downloaded set of diagnostic data from the scan tool to a cellphone; and

wirelessly communicating the downloaded set of diagnostic data from the cellphone to the remote database.

12. The process as recited in claim 1 wherein the downloaded set of diagnostic data includes information identifying operating characteristics of the home electronic device.
