Claim 5:
6. The method of claim 1, wherein updating the plurality of AD models based on the probability density functions created during the monitoring by estimating conditional probabilities of degradation of the vehicle component given a prior degradation of one or more other vehicle components related to the vehicle component further comprises:
updating a marginal probability of a first degradation of a first vehicle component;
updating a first conditional probability of the first degradation of the first vehicle component given a second degradation of a second vehicle component, the second degradation occurring prior to the first degradation;
updating a second conditional probability of the second degradation of the second vehicle component given the first degradation of the first vehicle component;
estimating a health status of the first vehicle component based on the first conditional probability; and
in response to the second conditional probability exceeding a threshold probability, identifying the second degradation as a root cause of the first degradation.
