Driver Seat Cushion Rear Vertical Position | -- | Varies | The scan tool displays 0 - 65,535 counts. The hall effect sensor provides a pulse signal with each rotation of the motor that the scan tool displays as counts. High count values indicate that the seat rear vertical is the up position, while low count values indicate that the seat rear vertical is in the down position.
Driver Seat Cushion Rear Vertical Switch | -- | Inactive | The scan tool displays Active or Inactive. This is the state of the rear vertical downward switch.
Driver Seat Horizontal Direction Command | -- | Inactive | The scan tool displays Inactive, Forward, or Rearward. When the seat horizontal switch is pressed or when a memory recall occurs, the scan tool displays the direction the memory seat module is commanding the seat horizontal motor.
Driver Seat Horizontal Position | -- | Varies | The scan tool displays 0 - 65,535 counts. The hall effect sensor provides a pulse signal with each rotation of the motor that the scan tool displays as counts. High count values indicate that the seat horizontal position is forward, while low count values indicate that the seat horizontal position is rearward.
Driver Seat Horizontal Switch | -- | Inactive | The scan tool displays Inactive, Forward, or Rearward. This is the state of the seat horizontal switch.
Driver Lumbar Support Horizontal Direction Command | -- | Inactive | The scan tool displays Inactive, Forward, or Rearward. When the lumbar horizontal switch is pressed, the scan tool displays the direction the memory seat module is commanding the lumbar horizontal motor.
Driver Lumbar Support Horizontal Switch | -- | Inactive | The scan tool displays Inactive, Forward, or Rearward. This is the state of the lumbar horizontal switch.
Driver Lumbar Support Vertical Direction Command | -- | Inactive | The scan tool displays Inactive, Up or Down. When the lumbar vertical switch is pressed, the scan tool displays the direction the memory seat module is commanding the lumbar vertical motor.
Driver Lumbar Support Vertical Switch | -- | Inactive | The scan tool displays Inactive, Up or Down. This is the state of the lumbar vertical switch.
Left Front Seat Blower Duty Cycle | -- | Varies | The scan tool displays 0 - 100 %. The value displayed is a PWM signal from the heated seat 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.
Left Front Seat Cushion Heating Command | -- | Inactive | The scan tool displays Inactive or Active. This parameter displays the commanded output from the heated seat module to the seat heater elements.
Left Front Seat Cushion Temperature Sensor | -- | Varies | The scan tool displays 0 - 5 V. The voltage displayed is an input to the heated seat module from the seat cushion temperature sensor. Higher voltage readings indicate cooler seat temperatures while lower voltage readings indicate warmer seat temperatures.
