Purpose and Role in the SRS System
The airbag sensor module in the Mercedes W164 functions as the central control unit for the SRS system. Based on data from acceleration sensors, signals from seatbelt pretensioners, and information from other vehicle controllers, it decides on the activation of the appropriate passive safety elements. This allows the system to adapt its response to the type and intensity of a collision in a fraction of a second.
As an SRS ECU airbag controller, this component communicates with the vehicle's data bus, stores error and event codes, and enables diagnostics using factory service testers. A correctly selected module is essential for the proper functioning of the entire airbag system.
