B2729 LINCOLN Description
The Seat Control Module E (SCME) monitors seat cushion temperature while it supplies voltage and ground to both blower motors. The SCME also supplies a variable voltage signal to control the blower speed. Cabin air enters the blower through a filter integrated to the blower motor housing. Heated or cooled air exits the blower motor and flows through the foam pad.
If the driver seat cushion blower motor temperature exceeds 70 ° C (158 ° F) in cool mode or 85 ° C (185 ° F) in heat mode for more than 4 seconds the SCME shuts down the driver seat system and sets this Diagnostic Trouble Code (DTC).
