A method operates an onboard power supply system in a motor vehicle. The onboard power supply system has a master controller and a slave controller, in which the master controller communicates with the slave controller via a subsidiary bus system and a further onboard power supply system component via a main bus system. Present requests are received in the slave controller and in response to the present requests, performing one of: putting the slave controller into an operating mode and switching the master controller to a transmission mode, in which the master controller coordinates communication between the slave controller and the onboard power supply system component; or putting the slave controller into a sleep mode and switching the master controller to an undertaking mode, in which the master controller responds to queries from the onboard power supply system component to the slave controller.
