Heating Characteristics

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 47°C (117°F).
In the MEDIUM setting, the DCSM is set to maintain TED temperature at approximately 55°C (131°F)
In the HIGH setting, the DCSM is set to maintain TED temperature at approximately 62°C (144°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.
