Short Drop/Raise Function
On opening the driver's or passenger's door the window is partially lowered to the clear of seal position (COS), on closing the relevant door the window will close fully up into the seal.
This function aids opening and closing of the doors.
The BC1 activates the window for 150 ms to open slightly. For the close procedure the window is powered for a maximum of 600 ms or until the cut-out current is seen by the BC1.
