Abstract

An unintended triggering of a safety device, such as an airbag in an occupant protection system, especially in motor vehicles is prevented by storing already during manufacturing of the module or modules, a blocking information in a memory location of the module or modules. The blocking information is preferably temporarily stored in place of a rated information, which is then overwritten when the module has been installed in the protection system for activating the system. In addition, the module is protected against electromagnetic and/or electrostatic disturbances at the input to the bus system.
