Abstract
A method is described for operation of a motor vehicle alarm system having a central control unit connected to several control units of the motor vehicle. All non-safety-relevant control units of the vehicle are bidirectionally connected to the central control unit of the alarm system, where a certain code for the respective activation state of the alarm system is stored in the non-safety-relevant control units and can be read out there. In the case of a replacement of control units the replaced control units are activated by the non-replaced control units in the original form when the vehicle is started. At least a part of the non-safety-relevant control units is deactivated or negatively affected in operation when the alarm system is not deactivated correctly.
