Front Seat Heating Control Module Scan Tool DataParameters

Parameter

Expected Value

Description

Operating Conditions: EngineRunning
Driver Seat Blower Duty Cycle	Varies	The scan tool displays 0–100-%. Thevalue displayed is a PWM signal from the seat heating controlmodule to the logic terminal of the seat blower motor. Highervalues indicate higher blower motor speeds while lower valuesindicate lower blower motor speeds.
Driver Seat Cushion Heating Command	Inactive	The scan tool displays Inactive or Active. This parameterdisplays the commanded output from the seat heating control moduleto the seat heater elements.
Driver Seat Cushion Temperature Sensor	Varies	The scan tool displays 0–5-V. Thevoltage displayed is an input to the seat heating control modulefrom the seat cushion temperature sensor. Higher voltage readingsindicate cooler seat temperatures while lower voltage readingsindicate warmer seat temperatures.
Driver Seat Heating/Venting/Cooling Level	Off	The scan tool displays Off, Low Medium, or High. When theheated or vented seat is active, this parameter displays theselected temperature setting.
Driver Seat Heating/Venting/Cooling Mode	Off	The scan tool displays Off, Back& Cushion Heat, orVent. This parameter indicates the heated or vented seat mode ofoperation.
Passenger Seat Blower Duty Cycle	Varies	The scan tool displays 0–100-%. Thevalue displayed is a PWM signal from the seat heating controlmodule to the logic terminal of the seat blower motor. Highervalues indicate higher blower motor speeds while lower valuesindicate lower blower motor speeds.
