Passenger Power Seat 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 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 seat 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.

If the Front Passenger Seat Control Module (SCMB) loses the signal from any of the motors, the affected seat motor operates in jog mode. Jog mode allows limited operation of the affected seat motor using only the seat control switch. When the seat control switch is operated in jog mode, the seat moves in the desired direction for one second, then stops. The seat control switch must be released, then pressed again in order to move the seat for an additional second. Jog mode is an indication that there is a seat motor sensor fault. If the seat is operating in jog mode, a DTC sets in the Front Passenger Seat Control Module (SCMB).
