Classification: CPC G | IPC G

Claim 15:
16. A system comprising:
a diagnostic knowledge module configured to:
determine a first most probable cause of an issue on a vehicle based on a first diagnostic trouble code identifying the issue and service procedures for the vehicle, the first diagnostic trouble code occurring at a first frequency on other vehicles;
determine a second most probable cause of the issue based on a second diagnostic trouble code identifying the issue and the service procedures for the vehicle, the second diagnostic trouble code occurring at a second frequency on the other vehicles that is less than the first frequency, each of the service procedures corresponding to one of the first and second diagnostic trouble codes;

a machine learning module configured to determine a third most probable cause of the issue based on repair data for other vehicles using machine learning;
a physics model module configured to determine a fourth most probable cause of the issue based on a physics model that relates an operating parameter of the vehicle to a failure mode of the vehicle;
an integrated MPC module configured to determine an integrated most probable cause of the issue based on the first, second, third, and fourth most probable causes; and
a user interface device (UID) control module that at least one of: visibly displays a message including the integrated most probable cause of the issue on a display;
audibly outputs a message including the integrated most probable cause of the issue via a speaker; and outputs a tactile message indicative of the integrated most probable cause of the issue via a vibrating motor.
