What Steps Should Be Taken When Servicing the Front Air Bag Sensor on Ford Focus?

During front impact severity sensor servicing, examine the RCM and sensor halls post crash, repair any damage and attach new parts, whether or not the airbag has deployed. When repowering, make sure the SRS is functioning, de-energized, sensor is disconnected, and that all the fasteners are tightened to the required torque.

How to service the Air Bag Sensor located in the front door for side impact on Ford Focus?

When replacing the front door side impact sensor, depower the SRS, trim panel, un- connector, then change the sensor and tighten it to 2 Nm. Check the sensor areas and RCM in the event of a crash. Do not give back the vehicle without getting the SRS operating and repair it with new parts.
