|What is B1034 MERCURY code meaning?

The engine must be running for the heated seat system to operate. The driver and passenger heated seat buttons are selected from the touchscreen interface, which initiates the CAN communication to request heated seat operation. Upon receiving the request, the Heating, Ventilation, and Air Conditioning (HVAC) Module supplies voltage to the appropriate driver and/or passenger seat cushion and backrest heater mats, which are connected in series. Temperature is maintained by the HVAC module using a sensor contained within the cushion heater mat. The HVAC module supplies a reference voltage to the temperature sensor and monitors the return signal from the temperature sensor for controlling current flow to the heater mats. The HVAC module remains on, heating the seat and maintaining temperature until commanded off from the touchscreen (or until the ignition is turned OFF).
