Kia Sorento: Description

The power liftgate is an electromechanical system designed to open and close the liftgate by pressing the button on the remote key (key fob), the console switch, the interior switch, or the switch on the liftgate outside handle. The power liftgate will reverse direction if resistance to movement is detected while the liftgate is opening or closing. Position and Direction of the Power Liftgate: The PTG system measures the liftgate position using a built-in Hall sensor inside the spindle drive unit motor. The direction of liftgate movement is determined by analyzing the direction of the drive unit motor. Hall sensor pulse counting (position detection) is active during power operation and manual operation. System Components

1
PTG module
The PTG control unit is located in the rear left side trim of the liftgate. The PTG drive unit operates two actuators (spindles) by measuring the drive motors. Anti-pinch strips (ATS) do not contain Hall sensors. The PTG monitors the anti-pinch function by analyzing resistance in the ATS.
2
PTG latch assembly
The PTG latch assembly consists of the power latch (A) and the power close unit (B). The power latch is located in the lower part of the liftgate panel.
3
PTG spindle
The PTG spindle opens and closes the liftgate by driving the motor.
4
Anti-pinch strip
During power closing or latching, the PTG system must reverse to full open if an anti-pinch strip signal is received. However, the anti-pinch strips will not operate when the liftgate is fully closed, fully open, or stopped.
5
SMK (Smart Key)
Press the power liftgate SMK switch for more than 0.5 seconds to open the power liftgate. The power open operation must be reversed when an additional open/close signal is received during opening/closing.
6
Interior switch
7
Liftgate interior switch
8
Liftgate buzzer
When the power operation cannot be performed as requested, or when liftgate control has been requested using the interior switch or RKE/SMK.
