Purpose and function in the steering system

The presented airbag module is designed specifically for the driver's side steering wheel in the fourth-generation Ford Mondeo. It is responsible for the correct deployment of the airbag in the event of a collision, working in conjunction with crash sensors and the SRS control unit. As a genuine Ford part, it maintains the correct mounting geometry, a shape tailored to the steering wheel rim, and compatibility with factory electrical harnesses.

Construction and integration with the steering wheel

The module is structurally prepared for central mounting within the steering wheel rim, in the place of the factory airbag. Integrated mounting points allow for stable seating of the component, and the manufacturer-provided electrical sockets allow for safe connection to the vehicle's installation. This ensures full functionality of both the airbag system and the horn buttons, which in this model are linked to the central part of the steering wheel.

Benefits of using an original module

Using an original airbag module in the Ford Mondeo Mk4 ensures:

• compliance with the vehicle's factory safety parameters,
• secure fitment to the steering wheel and steering column structure,
• proper cooperation with the SRS control system and the airbag warning light on the instrument cluster,
• a consistent appearance of the central part of the steering wheel with other interior elements.

For the user, this means stable operation of the passive safety system and no issues with error messages resulting from incompatible replacements.

Condition of the part and service application

The offered module is a used part, which allows for reduced repair costs while maintaining the original manufacturer's specifications. It is suitable both for replacement after airbag deployment and for system maintenance when it is necessary to swap out a faulty module. When combined with a properly selected steering wheel and a functional SRS controller, it enables the restoration of full safety system functionality in the vehicle.
