MINING METHODOLOGY TO ELIMINATE INAPPROPRIATE SETTING OF ERROR CONDITIONS USING OPERATING PARAMETERS
First Claim
1. A method for reducing or eliminating improper error conditions in a system, said method comprising:
- collecting field failure data identifying built-in tests, diagnostic trouble codes and parameters of the system that are used to set the diagnostic trouble codes;
transforming the collected data into a format more appropriate for human analysis;
pre-processing the transformed data to identify and remove information that could bias the human analysis;
performing data mining and analysis for detecting inappropriate settings of fault codes in the pre-processed data; and
providing the mined data to a subject matter expert for review to determine whether a diagnostic trouble code has been triggered because of improper values of operating parameters.

Abstract
A system and method for reducing or eliminating built-in tests and diagnostic trouble codes that are set as a result of improper parameter values. The method includes collecting field failure data that identifies diagnostic trouble codes and parameters of the system that are used to set diagnostic trouble codes. The method transforms the collected data into a format more appropriate for human analysis and pre-processes the transferred data to identify and remove information that could bias the human analysis. The method includes plotting linear and nonlinear combinations of operation parameters, performing data mining and analysis for detecting inappropriate settings of fault codes in the pre-processed data and providing the mined data to a subject matter expert for review to determine whether a diagnostic trouble code has been issued because of improper parameters.

10. A method for reducing or eliminating improper error conditions in a vehicle, said method comprising:
-
collecting field failure data identifying diagnostic trouble codes and parameters of the vehicles that are used to set the diagnostic trouble codes, said parameters including one or more of voltage, pressure and temperature; transforming the collected data into a format more appropriate for human analysis; pre-processing the transformed data to identify and remove information that could bias the human analysis including identifying missing values and information; performing data mining and analysis for detecting inappropriate settings of fault codes in the pre-processed data that includes employing decision trees to reconstruct a probabilistic fault tree using parameter identifiers; providing the mined data to a subject matter expert for review to determine whether a diagnostic trouble code has been triggered because of improper values of operating parameters that includes determining whether a particular parameter could exist for a particular system condition; and providing recommendations to adjust the setting of the diagnostic trouble code if it is determined that a particular parameter could not exist for a particular system condition. - View Dependent Claims (11, 12, 13)
