Electric Cooling Fan Control
WARNING: This page is about a different car, the 2018 Jaguar XF, 2017 Jaguar XF, and 2016 Jaguar XF. However, it is still accessible from the selected car via links, so may be relevant.
The ATCM determines the amount of cooling fan duty required using the refrigerant pressure combined with the ambient air temperature. The cooling fan duty request is broadcast to the PCM on the HS CAN comfort and powertrain systems buses via the BCM/GWM assembly.
