Control method and module for occupant protection systems with an action to prevent premature triggering
First Claim
1. A method for preventing a premature, accidental triggering of at least one module (3) including at least one memory location in an occupant protection system for a motor vehicle, said method comprising the following steps:
- a) first entering a blocking information into said at least one memory location for preventing triggering of said at least one module until said occupant protection system has been installed in said motor vehicle, b) installing said occupant protection system in said motor vehicle, and c) second entering a rated information into said at least one memory location thereby cancelling said blocking information, whereby the same memory location is used first for temporarily storing said blocking information and then for storing said rated information after said installation is completed.

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.
