Pic. 2.50. Cooling Fan Control Wiring Diagram
Unlike the previous electric fan system, the coolant temperature switch has been removed. Instead, a coolant temperature sensor is used to control the fan motor, simplifying the system. The cooling fan control system turns on/off the 3 fan relays according to the coolant temperature and air conditioning system operation. When the fans are on, the two fan motors can run at low (successively) or high (parallel) speed.
