Crash Unlocking
WARNING: This page is about a different car, the 2018 Jaguar XE and 2017 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
If a crash occurs that triggers deployment of the airbags, then the BCM/GWM will unlock the doors. The BCM/GWM is informed of the crash by a hardwired input from the RCM (Restraints Control Module).
