    processing, by the processor, the fault data with at least one 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 decision;

    processing, by the processor, the first propositions set and the second propositions set to determine a probability mass; and

    generating, by the processor, a diagnosis of the CAN bus based on the decision and the probability mass.
