Radiator Cooling Fan Motor Relay: Description and Operation
The Electronic Control Assembly (ECA) monitors coolant temperature, vehicle speed, and air conditioning status to determine if cooling fan operation is
required. When the ECA determines a need for cooling fan operation, it sends a signal to the Integrated Relay Control Module (IRCM) to run the fan at
the required speed.
