Abstract

A control device and corresponding motor vehicle for connecting a CAN bus to a radio network, having the following features: the control device includes a wireless controller, a microcontroller, a first CAN transceiver and a second CAN transceiver; the microcontroller is connected, on the one hand, to the wireless controller and, on the other hand, to the CAN transceivers; the first CAN transceiver is connected to the second CAN transceiver; the first CAN transceiver is configured in such a manner that it suppresses transmission via the CAN bus and supports reception via the CAN bus in a normal mode and supports transmission and reception in a diagnostic mode; and the second CAN transceiver is configured in such a manner that it changes the first CAN transceiver from the normal mode to the diagnostic mode when the second CAN transceiver receives a wake-up frame via the CAN bus.
