Some 2011-2012 Lincoln MKS and MKT vehicles built on or after September 1, 2010, and equipped with dual engine cooling fans may exhibit a lack of air conditioning performance while the vehicle is stationary or moving at slow speeds, and/or an overheat condition. DTCs P0217, P1299 and P1285 may be present.
Using the IDS with a release of 87.05 and higher, check the PCM for a later calibration. Make sure the PCM is updated with this higher calibration. Using IDS, select Data Logger, select Output State Control, command the Cooling Fan Speed Desired PID to High speed (FAN_CTRL# or FAN_DSD# - above 90%) for 1 minute and verify cooling fan operation.
Also, check serial numbers to verify if the assembly is OEM or aftermarket.
For MKS vehicles, replace the cooling fan motor and control module assembly. Foe MKT vehicles, remove the cooling fan motor and control module assembly. Remove the cooling fan module from the original fan motor assembly and transfer onto the new cooling fan motor assembly. Tighten screws to 60 in-lb. Install the assembly. Check/top off coolant level as needed.
