Driver Seat Module (DSM) Hard Stop/Soft Stop

A hard stop occurs when the seat track or backrest (recline) axes physically reach the end of travel. A soft stop occurs when the seat stops before physically reaching the end of travel. The hard stop is set by seat design and cannot be changed or adjusted. The soft stop is set by the DSM. To prevent unnecessary stress on the seat, the DSM sets 2 soft stops for each moving axis of the seat track and backrest. The DSM uses a preset distance from the hard stop to determine where the soft stop occurs. When an axis reaches the hard stop and the switch is held for approximately one second, it then backs up 180 milliseconds and establishes the soft stop for that axis in that direction.
