Abstract
A vehicle includes a plurality of controllers. During a key-off mode, a master controller may maintain operation of a predetermined set of controllers by broadcasting a power sustain request on a communication bus. Responsive to a loss of communication for a time exceeding a predetermined amount of time with one or more of the predetermined set of controllers, the master controller may be programmed to stop broadcasting the power sustain request to cause the predetermined set of controllers to power down.
