Heating Characteristics

WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: The presence of overtemperature faults (DTCs B2729, B2730, B272A and B272B) can be induced by incorrect operation of the climate controlled seat system after an initial heat setting has been attained. If a heat setting is repeatedly turned OFF and ON in an attempt to increase the seat temperature, an overtemperature condition can result and the DTCs will be set.

In the LOW setting, the DCSM is set to maintain TED temperature at approximately 46°C (115°F).
In the MEDIUM setting, the DCSM is set to maintain TED temperature at approximately 60°C (140°F).
In the HIGH setting, the DCSM is set to maintain TED temperature at approximately 65°C (149°F).
When heating, the DCSM will vary the speed of the fans and the TED duty cycle in order to reach and maintain the temperature determined by the switch setting.
Engine must be running over 350 rpm and seat heating does not time out.
