Driver Seat Backrest
WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
The driver seat backrest contains a bi-directional motor which is integral to the seat backrest frame assembly. If equipped, the seat backrest may also contain an upper backrest pivot motor. The seat backrest motor(s) 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(s) move the seat backrest forward/backward depending on the polarity of voltage supplied from the DSM.
