Powertrain control module (PCM)
The cooling fan motor speed is controlled by the cooling fan motor module as a function of input signals from the PCM.
The cooling fan motor module is located on the cooling fan shroud.
Communication between the cooling fan motor module and the PCM is done on the controller area network (CAN) bus using pulse width modulation.
