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.

Method and system for optimizing vehicle diagnostic trees using similar templates

A method and system for adaptively modifying diagnostic vehicle information is provided. A system can automatically optimize default OEM diagnostic vehicle information by recognizing when to make text and non-text modifications within the information. Manual changes that are made once can be learned and used over and over again. Modifications may be made based on a desired use of the diagnostic vehicle information.

Method and system for adaptively modifying diagnostic vehicle information

Stationary power equipment including a sensing device configured to collect data associated with an operation of the equipment, and a data storage device configured for storing the collected data. Information derived from the collected data may be transmitted to a remote system via a data transmission network, or be downloaded to a data storage medium or a diagnostic device. An operation condition of the stationary power equipment is determined based on the information. Responsive to the operation condition, the power equipment receives data that is selected based on the operation condition, and modifies an operation of the power equipment based on the received data.

Intelligent stationary power equipment and diagnostics

A system and method for identifying and substituting procedures in an OEM diagnostic tree with alternate procedures analyzed by highly experienced technicians to eliminate the use of potentially unavailable equipment and make the diagnostic tree more accessible to a greater number of technicians. The system includes a diagnostic tree editor and a library.

Diagnostic tree substitution system and method

A system for test procedures using pictures for a vehicle diagnostic system that includes a processor, a storage device in communication with the processor, a diagnostic routine that is executed by the processor, and a display device also coupled to the processor. The storage device may house a database that includes a library of vehicle information items. These vehicle information items include text items that may relate to several items, for example: 1) a fault that may be experienced by a vehicle under diagnosis; 2) a test that may be performed on the vehicle for the purpose of diagnosing the causes of the faults; or 3) a solution that may be used to correct the faults. Further, the vehicle information items may also include a library of picture items that correspond to the text items.

Test procedures using pictures

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.

System and method for optimizing vehicle diagnostic tress using similar templates

A method for test procedures using pictures for a vehicle diagnostic system that includes providing text items, examining text items, accessing a database of picture items corresponding to text items, correlating picture items with at least a portion of the text items, replacing the at least a portion of the text items with the corresponding picture items, and displaying an image including at least one picture item.

A method is provided for updating a fault tree used in diagnosis of a condition of a machine. The fault tree is a sequence of test modules. Each of the test modules is assigned a confidence score indicating the likelihood that the test module will lead to a diagnosis. The method comprising the steps of obtaining service data from a plurality of service occasions for like machines, revising the confidence score for at least one test module in the fault tree based on the service data; and revising the sequence of the test modules in the fault tree based on the revised confidence score(s). The sequence is revised such that the most likely modules to result in a diagnosis are listed first, and the least likely ones are listed last. The re-ordering is based on feedback from actual service instances in the field, and thus is more likely to reflect real-world conditions. The result is that service technicians using the revised fault trees work more efficiently, at least on a statistical basis.
