Seat Backrest - With Memory
WARNING: This page is about a different car, the 2019 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The seat backrest contains a bi-directional motor which is integral to the seat backrest assembly. The seat backrest motor contains a Hall-effect sensor which provides seat backrest position information to the DSM for setting/obtaining desired preset seat memory positions. The seat backrest motor moves the seat backrest forward/backward depending on the polarity of voltage supplied from the DSM.
