Power Tailgate System Description - Components
Driver's Power Tailgate Switch
The power tailgate can be open/closed automatically by using the driver’s power tailgate switch.
Remote
The power tailgate can be open/closed automatically by pressing the power tailgate button of the remote.
Tailgate Outer Handle Switch
The tailgate outer handle switch can be used to manually open the power tailgate.
Power Tailgate Inside Switch
The power tailgate inside switch is equipped on the lower tip of the tailgate, and it can be used to automatically close the power tailgate.
Power Tailgate Sensor
The power tailgate sensor detects the opening/closing angle and the opening/closing speed of the power tailgate.
Power Tailgate Inside Beeper
The tailgate inside beeper generates a sound during the operation of the power tailgate.
Power Tailgate Drive Unit
The power tailgate drive unit consists of the motor, magnet clutch, gear, and power tailgate sensor, and receives signals from the power tailgate control unit to open or close the tailgate. When the power tailgate drive unit receives signals from the power tailgate control unit, it activates the magnet clutch, motor, and gear to rotate the arm.
Power Tailgate Closer Unit
The closer unit consists of the closer motor, the sector gear, the latch, and so forth. Several switches are used to detect the position of the component parts.

Upon a tailgate close request, the latch switch detects that the tailgate is in the half-shut position. Then, the closer motor begins to rotate in the closing direction until the tailgate reaches the full-close position.

Upon a tailgate open request, the closer motor begins to rotate in the opening direction until the sector gear unlocks the latch.
Pinch Sensor
The pinch sensor is attached at either end of the tailgate and is equipped to prevent the pinching during auto close. When the pinch sensor is compressed, the embedded conductive rubbers contact each other and the resistance value of the sensor varies. This signal is transmitted to the power tailgate control unit and the unit reverse the operation from the auto close to the auto open based on the information.
