Electric Cooling Fan

WARNING: This page is about a different car, the 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

The electric cooling fan is operated by the engine cooling fan control module integrated into the cooling fan motor. The engine cooling fan control module regulates the voltage, and thus speed, of the cooling fan motor.

The electric cooling fan receives a battery feed from the rear Engine Junction Box (EJB). An ignition signal is received from the Powertrain Control Module (PCM) relay located in the rear EJB. The PCM relay is controlled by the PCM.

The PCM calculates the required fan speed from the engine coolant temperature and Automatic Transmission Fluid (ATF) temperature. Under hot operating conditions, the electric cooling fan may continue to operate for 5 minutes after the engine has been switched off.

The engine cooling fan control module is controlled by the Powertrain Control Module (PCM) through a Pulse Width Modulation (PWM) signal.
