Engine Coolant Level Sensor
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 the engine coolant level in the coolant expansion tank decreases below a predetermined value, the engine coolant level sensor connects a ground to the Body Control Module/Gateway Module (BCM/GWM) assembly. The BCM/GWM sends a message to the Instrument Cluster (IC) on the High Speed (HS) Controller Area Network (CAN) comfort systems bus to display a warning message.
