Abstract:
A motor vehicle has a master bus device that is designed to use a vehicle communication bus of the motor vehicle to exchange messages with slave bus devices. A transmission device of the master bus device cyclically exchanges the messages with the slave bus devices on the basis of a schedule For making efficient use of the vehicle communication bus by the schedule-controlled master bus device, the transmission device is designed to receive a diagnosis request signal via a data input that is different than the bus port of the master bus device and to take the diagnosis request signal as a basis for interrupting the cyclic processing of the schedule and to exchange at least one special message that is different than the messages stipulated in the schedule with at least one of the slave bus devices and then to continue the processing of the schedule.
