DSM Hard Stop/Soft Stop

WARNING: This page is about a different car, the 2023 Ford Bronco Sport. However, it is still accessible from the selected car via links, so may be relevant.

A hard stop occurs when one of the memory seat track or backrest axes physically reach the end of travel and can go no further. A soft stop occurs when the seat stops before it physically reaches the end of travel. The hard stop is part of the seat design and cannot be changed or adjusted. The soft stop is set by the DSM. The seat track axes are forward/rearward and up/down. The backrest axis is recline forward/backward. To prevent unnecessary stress on the seat and motors, the DSM sets soft stop positions, 2 for each moving axis. 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, the DSM briefly reverses direction and establishes the soft stop for that axis in that direction. The DSM uses this back up strategy to check sensor integrity any time movement has stopped prematurely due to a sensor failure or obstruction.
