A vehicle includes a first controller that sends a request to enter a lower power mode, and a plurality of second controllers. The second controllers each periodically send the first controller signals indicating operation in a normal power mode while being powered by a primary power converter, and responsive to receiving the request, do not send the signals during the low power mode while being capable of powered by an auxiliary power converter that has a maximum power limit less than the primary power converter. Also, the first controller, responsive to not receiving the signals for a predetermined period of time, disconnects the first and second controllers from the primary power converter.
