Its task is to transmit information about seat occupancy and the conditions under which the airbag should be activated or deactivated to the main SRS controller.

A properly functioning module:

• works with the passenger seat occupancy mat and other SRS system components,
• helps eliminate airbag errors appearing on the instrument cluster,
• ensures the consistency of the safety system operation in accordance with the manufacturer's specifications.

Benefits of using an original BMW module

The original BMW passenger seat airbag sensor module has been designed for the specific electrical architecture of the 7 Series E65/E66, thanks to which it maintains full compatibility with the factory wiring, software, and control logic. In practice, this means:

• stable cooperation with other controllers in the vehicle,
• no need for installation modifications or the use of adapters,
• preservation of original passive safety parameters.

A component from the Electronic control modules and controllers group of this type is particularly important for professional SRS system repairs after the occurrence of errors related to the passenger seat or after replacing the seat itself.

Product characteristics and installation

The offered module is a used part, sourced from dismantling, which in many cases allows for a significant reduction in repair costs compared to purchasing a new controller.
