Abstract
A system for a vehicle includes a controller and contactor arranged to close responsive to current magnitude through a coil thereof exceeding a first threshold. The controller, following a request to open the contactor, applies current to the coil at a magnitude less than the first threshold for a duration, and responsive to peak current through the contactor during the duration being less than a second threshold, prevents start of the vehicle.
