Abstract
A method of operating a motor vehicle includes a vehicle controller receiving, from a first feedback sensor of an HV component, a first feedback signal indicative of an electrical characteristic of the HV component, and then detecting an HV system fault if the first feedback signal is less than a predefined electrical threshold. Upon detecting the system fault, the controller commands the HV component to operate at a commanded set-point; after sending the command, the controller receives, from a second feedback sensor of the HV component, a second feedback signal indicative of an operating characteristic of the HV component. An HV pathway failure is detected if the second feedback signal is not equal to or within a predefined operating range of the commanded set-point. Upon detecting the pathway failure in an HV electrical pathway of the HV component, the vehicle controller transmits a command signal to take a remedial action.
