Abstract

A method for checking an interface module, the interface module returning to the processor, using a second data message, stored values representing sensor values, after a request for a test by a processor using a data message. Using these firm sensor values, the processor can check the functioning of the interface module and its own algorithm. A safety module, which also picks up the sensor values, also checks its functioning with them, since the safety module is a redundant hardware path to the processor and is used as a plausibility check for the release decision of means of restraint. The interface module is changed into a test mode as soon as it receives the first data message from the processor, and it then suppresses the transmission of the real sensor values which were received from connected sensors.
