Abstract
A vehicle includes an electrically-driven motor configured to actuate a vehicle component and a power source configured to provide power to the motor over an electrical circuit. The vehicle also includes a controller programmed to monitor at least one signal indicative of motor output and store data indicative of a resistance in the circuit. The controller is also programmed to issue a resistance state of health signal in response to the resistance in the circuit exceeding a predetermined resistance threshold.
