Abstract
A method and system for transmitting control data between a vehicle data recorder arranged in a motor vehicle and a test device arranged outside the motor vehicle. A random code is generated by the vehicle data recorder or by the test device as a connection code. The random code is detected and input device not generating the random code. After the random code has been input into the device coupling is effected automatically via a short-distance radio link between the devices. Subsequently the control data is transmitted by the vehicle data recorder to the test device via the short-distance radio link. After the control data transmission has ended, the short-distance radio link between the vehicle data recorder and the test device is separated and the random code is deleted in the vehicle data recorder and in the test device.
