Front Seat Heating Control Module Scan Tool Data Parameters

Parameter	Expected Value	Description
Operating Conditions: Engine running
Driver Seat Blower Duty Cycle	Varies	The scan tool displays 0-100 %. The value displayed is a PWM signal from the seat heating control module to the logic terminal of the seat blower motor. Higher values indicate higher blower motor speeds while lower values indicate lower blower motor speeds.
Driver Seat Cushion Heating Command	Inactive	The scan tool displays Inactive or Active. This parameter displays the commanded output from the seat heating control module to the seat heater elements.
Driver Seat Cushion Temperature Sensor	Varies	The scan tool displays 0-5 V. The voltage displayed is an input to the seat heating control module from the seat cushion temperature sensor. Higher voltage readings indicate cooler seat temperatures while lower voltage readings indicate warmer seat temperatures.
Driver Seat Heating/Venting/Cooling Level	Off	The scan tool displays Off, Low Medium, or High. When the heated or vented seat is active, this parameter displays the selected temperature setting.
Driver Seat Heating/Venting/Cooling Mode	Off	The scan tool displays Off, Back & Cushion Heat, or Vent. This parameter indicates the heated or vented seat mode of operation.
Passenger Seat Blower Duty Cycle	Varies	The scan tool displays 0-100 %. The value displayed is a PWM signal from the seat heating control module to the logic terminal of the seat blower motor. Higher values indicate higher blower motor speeds while lower values indicate lower blower motor speeds.
Passenger Seat Cushion Heating Command	Inactive	The scan tool displays Inactive or Active. This parameter displays the commanded output from the seat heating control module to the seat heater elements.
