Code B272E Mercury Description

The Seat Control Module E (SCME) supplies voltage and ground to the backrest and cushion blower motors. The blower motors are independently controlled by separate speed control circuits from the SCME.
If either the blower voltage supply or return circuits are open (to both cushion or backrest blowers) or shorted to voltage, the Diagnostic Trouble Code (DTC) is set and after 4-6 seconds the SCME disables outputs to the driver seat. The DTC also sets if the blower voltage supply or return circuit is open to only one blower when SCME supply voltage is less than 12 volts.
