WARNING: This page is about a different car, the 2018 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
The front door side impact sensors monitor air pressure within the door in order to detect certain crashes, such as a side impact. They are hardwired to the RCM. Mounting position and orientation is critical for correct operation of the front door side impact sensors.
