System Initialization

System initialization is needed to recognize the closing position of the tailgate.

The initialization process after battery power is reset, is to find the maximum opening and closing position of the tailgate.

After the successful initialization, the tailgate's opening and closing position have to be recognized to guarantee the general tailgate's opening and closing.
