NOTE:
Some vehicles are equipped with an Integrated Relay Controller Module (IRCM) which is part of Ford Electronic Engine Control (EEC-IV) system. Designated diagnostic codes must exist prior to testing IRCM. For complete information on Ford EEC-IV system, see the appropriate article in the ENGINE PERFORMANCE section.
Electric cooling fan system consists of either a two-speed or one-speed fan. Two-speed fan is used on 3.0L (except SHO) and 3.8L A/T models; one-speed fan is used on Taurus 3.0L SHO.
On 3.0L A/T models, low-speed cooling fan motor operation is achieved by using a dropping resistor in series with the motor. All other models use a two-speed fan motor. Cooling fan operates only when ignition is on.
