Passenger Power Head Restraint Operation
WARNING: This page is about a different car, the 2018 Lincoln Continental. However, it is still accessible from the selected car via links, so may be relevant.
The power head restraint assembly contains a seat headrest motor (up/down) and a seat head restraint forward/rearward motor. The passenger seat control switch communicates over a LIN to the Front Passenger Seat Control Module (SCMB). When the Front Passenger Seat Control Module (SCMB) receives the input from the seat control switch, the Front Passenger Seat Control Module (SCMB) provides power the appropriate head restraint motor until the input is removed. The motor circuits are normally grounded through the Front Passenger Seat Control Module (SCMB). The Front Passenger Seat Control Module (SCMB) internally switches the appropriate circuit from ground to voltage to operate the motors.
