Impact Sensor
WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
Impact sensors are installed in the front and both sides of the vehicle. The two front impact sensors are attached to the front end carrier, behind the inboard edge of each headlamp. The side impact sensors are attached to the base of each C/D pillar and to the inner panel of each rear quarter wheel housing, adjacent to the rear door latch strikers.
The impact sensors are accelerometers that allow the RCM to detect the sudden vehicle acceleration that occurs during an impact.
