When one of a plurality of conditions exist to keep one or more of the plurality of buses of the CAN awake during an ignition-off period, the supervisory controller sends a signal to the SGW module that causes it to only communicate on a specific set of buses of the plurality of buses of the CAN to thereby reduce energy consumption of components on the CAN that would have otherwise been awoken by the SGW module.
