Engine
– Cooling Fan High-Speed Circuit Description: The engine
control module receives the engine coolant temperature
sensor and air pressure switch signals. ECM monitors
conditions that meet the cooling fan how-speed running
conditions, ECM controls the engine wiring harness
connector EN01 terminal No.52 internal ground, and the
how-speed cooling fan relay pull-in. Power passes through
the how speed relay terminal No.87 to reach the cooling fan
wiring harness connector CA16 terminal No.2 and then
through the speed limit resistor, and finally reaches to the
paralleled two fan motors. Fan motors negative is
connected to the ground through the cooling fan wiring
harness connector CA16 terminal No.3. Therefore, the
how-speed fan motor starts running.
