A diagnostic system for a vehicle, includes a computer storing software on a computer readable media, configurable for setting up recording of vehicle operations, selecting from a plurality of customizable triggering operations according to Boolean logic, and a vehicle communication interface detachably connected to the computer, being setup by the computer for recording of vehicle operation while the vehicle is operating and recorded information stored in a computer readable media of the vehicle communication interface being reviewed by the computer, and detachably connected to the vehicle for recording of the vehicle operations.

Customizable initiation of data recordings

A dynamic diagnostic plan generator arranges diagnostic test procedures related to a vehicle/power tool/patient symptom or operational problem in a sequence based on a probabilistic Failure Mode and Effects Analysis (FMEA). The diagnostic plan generator also tracks a vehicle/power tool/patient state, and provides instructions for test preparation steps and instructions for performing the diagnostic test procedures. The plan generator further generates schematic illustrations of the diagnostic test procedures, and creates a diagnostic data structure containing information related to the diagnostic test procedures. In addition, the diagnostic plan generator sends and receives information regarding actual failure mode occurrences, for example, to and from a central database. Furthermore, the diagnostic plan generator facilitates the creation of failure mode tests by an expert diagnostics author.

Dynamic decision sequencing method and apparatus for optimizing a diagnostic test plan

In a computer-implemented method of optimizing a diagnostic test sequence to diagnose a medical condition of a subject. A group of diagnostic tests related to a symptom is determined from a pool of diagnostic tests. A probabilistic failure mode analysis is conducted to determine the efficacy of each of the diagnostic tests based on historical outcomes of actual diagnostic testing. The comparative utility of each diagnostic tests based on a plurality of factors that can affect problem resolution is analyzed. A weight is assigned to each factor involved in the probabilistic failure mode analysis. The diagnostic tests are ordered based upon at least one of: a probability of the diagnostic test identifying a cause of the failure mode in a minimum amount of time; a probability of the diagnostic test identifying the cause of the failure mode at a minimum cost; and a relative weighting of minimizing time versus minimizing cost. A first diagnostic test is selected from the group based at least in part on a probabilistic failure mode analysis and the weighted factors involved therein.
