According to page EC-486 of FSM, "Cooling fan motor receives cooling fan motor operating voltage from cooling fan control module. The revolution speed of cooling fan motor is controlled by
duty cycle of the voltage." Ie, it turns the power on and off real fast. An oscilloscope would work to check output.
