摘要： A method for the maintenance or extension of the range of functions of a self-propelled machine, in particular a tandem roller, single-drum roller, rubber-wheeled roller, refuse compactor, road finisher, road milling machine, recycler or stabilizer, comprising the steps: generating a code which can be identified at a short distance by a control device of the machine either automatically by the control device after a maintenance interval has expired, or after a request by an operator for an extension of the range of functions, wherein the code contains information about at least one machine state that changes in the course of operation of the machine, identifying the code by a mobile terminal, transmitting the information contained in the code to a central server, transmitting a release code from the server to the mobile terminal, transmitting the release code to the control device of the machine, enabling the maintenance interval or the extension of the range of functions.
