Kia Sorento: Description
Power tailgate is an electro-mechanical system designed to provide power
opening and closing of the tailgate through the push of a button of a remote
key (fob), console switch, inner switch or an outside handle switch of the tailgate.
The power tailgate will reverse direction of travel if resistance to movement
is detected while the tailgate is being opened or closed.
Tailgate Position And Direction
The PTG system will measure the Tailgate position via an integrated hall
sensor inside the Spindle drive unit motor.
The moving direction of tailgate will be detected by analyzing the direction
of the drive unit motor.
The hall sensor pulse counting (position detection) is active during power
and manual operation mode.
