Application and function in the safety system

The described curtain airbag module is designed for installation on the right side of the vehicle, in the headliner zone, along the edge of the roof and pillars. It works with collision sensors and the SRS controller, creating a side protective barrier for the driver or passenger in the event of a side impact or rollover. A correctly installed component helps reduce the risk of head contact with the side window, pillar, or other interior elements.

As an original Ford part, the module is structurally matched to the body geometry of the Ford Focus Mk2 ST, which facilitates installation in the factory mounting points of the headliner and wiring harnesses. This ensures the correct position of the curtain relative to the windows and pillars, which is crucial for the effectiveness of the system.

Construction, installation, and integration with the headliner

The curtain airbag module is a component intended for installation under the headliner, in the immediate vicinity of the side roof edge. The design provides for cooperation with factory brackets, clips, and guides, which allows for orderly routing of the element along the entire protected zone. This makes it possible to maintain the aesthetics of the interior and the proper operation of the headliner after reassembly.

When replacing the module, it is recommended to:

• remove the headliner while maintaining the sequence of disconnecting the finishing elements,
• check the condition of the mounts and anchoring points within the roof and pillars,
• verify the correct routing of harnesses and connections with the SRS installation,
• install in accordance with the service procedure provided for the Ford Focus Mk2 ST.

This approach allows for maintaining the proper tension and position of the curtain, which is important for its correct deployment in case the system is triggered.

Characteristics of the used component

The offered module comes from the used Ford parts segment, which allows for economical repair while maintaining the original design and compatibility with the factory safety system. In the case of SRS elements, it is particularly important to use components compatible with the given vehicle model, which is why the selection of the correct module for the Ford Focus Mk2 ST has a direct impact on the correct operation of the entire system.

Before installation, it is recommended to verify compatibility with the vehicle and perform SRS system diagnostics after installation to confirm the absence of errors in the controller and proper communication with the newly installed module. Such a procedure is standard for professional repairs of passive safety systems.

Benefits of using an original curtain module

Using an original curtain airbag module in a Ford Focus Mk2 ST ensures:

• full integration with the body structure – matching the shape of the roof, pillars, and headliner,
• compatibility with the factory SRS controller and collision sensors,
• the ability to restore the level of side protection designed by the manufacturer,
• easier installation thanks to the provided mounting and routing points.
