Table 2: | Front Seat Heating Control Module Scan Tool OutputControls |
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. |
Passenger 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. |
Passenger 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.
