Maximum Point for Opening
Above this position a start in opening direction could make the tailgate move beyond the Maximum Basic Position and overload the mechanical system (hinges).

Therefore the start of an opening action above this point is disabled.

Anyway the tailgate moves beyond this point, if it has been started at a lower position.
Learned Mechanical End Position
This is the mechanical block position while opening and is considered to be 100% opening. During the first tailgate opening this position is learned.

After learning, the tailgate will not move beyond the Maximum Basic Position, which is defined by the Learned Mechanical Position - Security Distance.

All positions are defined by parameters in the ECU or programmed by the user (Basic Programmed Position)
