ISSUE
Some 2011 Edge and MKX vehicles built on or before 9/1/2010, may experience the outside air temperature (OAT) reading inaccurate and/or slow to
update in actual ambient temperatures 70 °F (21 °C) or above. Vehicles equipped with dual automatic temperature control (DATC) System may also
experience a lack of A/C cooling at startup. This typically occurs when the OAT sensor is (10-15 °F or more) lower than the actual ambient temperature
during starting up. This causes reduced air[low because the heating ventilation air conditioning (HVAC) blower speed is not adequate for the climate
conditions.
ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
1. Reprogram the HVAC module to the latest calibration using IDS release 69.05 or higher. This new calibration is not included in the VCM 2010.9
DVD. Calibration files may also be obtained at the website.
NOTE
AFTER REFLASH THE OAT DISPLAY WILL NEED A FEW MINUTES, INITIALLY, OF CONSTANT DRIVING TO OBTAIN THE
CURRENT OUTSIDE AIR TEMPERATURE.
