    Abstract: A distributed vehicle health management system includes a vehicle-based diagnostic processor executing diagnostic routines in a vehicle. The diagnostic routines generate diagnostic data. A processor-based device executes advanced vehicle health management routines. The processor-based device determines a state of health of a component as a function of the diagnostic data. A telematics device communicates at least one of state of health data and diagnostic data from the vehicle. A remote entity disposed remotely from the vehicle. The remote entity receives data via the telematics device, the data being a selective subset of data output from at least one of the vehicle-based processor and processor-based device. The remote entity executes calibration routines as a function of the data received by the vehicle for calibrating at least one of the diagnostic routines and health management routines.

    Abstract: A controller area network (CAN) includes a CAN bus having a CAN-H wire, a CAN-L wire, and a pair of CAN bus terminators located at opposite ends of the CAN bus. The CAN further includes a plurality of nodes including controllers wherein at least one of the controllers is a monitoring controller. The monitoring controller includes a detection control routine for isolating faults on the CAN bus including measuring a CAN-H wire voltage, measuring a CAN-L wire voltage, and isolating a short fault based upon the CAN-H wire voltage and the CAN-L wire voltage.

    Abstract: A method of detecting a ground fault in a faulty electronic control unit. A ground fault detection technique executed by a processor is enabled. The processor determines a message count for each respective electronic control unit transmitted during a ground offset condition over a predetermined time period. The message count includes messages communicated within a communication bus having a measured voltage at least a predetermined voltage value above an expected voltage value. The message counts for each respective electronic control unit are normalized. The faulty electronic control unit is identified as a function of the normalized message counts. A fault signal is output to identify the fault electronic control unit.

    Abstract: Methods and system are provided for monitoring a controller area network (CAN) bus. In one embodiment, a method includes: receiving fault data associated with the CAN bus; processing, by a processor, the fault data with a software based method to determine a first propositions set; processing, by the processor, the fault data with a hardware based method to determine a second proposition set; processing, by the processor, the first propositions set and the second proposition set to determine a fault decision; and generating, by the processor, a diagnosis of the CAN bus based on the fault decision.
