Coolant Level Sensor
WARNING: This page is about a different car, the 2018 Land Rover Range Rover, 2017 Land Rover Range Rover, and 2016 Land Rover Range Rover. However, it is still accessible from the selected car via links, so may be relevant.
If the coolant level in the expansion tank decreases below a predetermined value, the coolant level sensor connects a ground to the Body Control Module/Gateway Module (BCM/GWM) assembly, which 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
