Memory Seat Operation: Notes

The driver seat control switch provides a ground signal to the DSM only when activated. This ground signal causes the DSM to power the appropriate motor until the input is removed. The motor circuits are normally grounded through the DSM. The DSM internally switches the appropriate circuit from ground to voltage to operate the motors.

As the seat is adjusted, the DSM monitors the motor position sensors to record the current seat position. The DSM removes voltage from the motor upon termination of the seat control switch input, when a target position has been reached during a memory recall operation, or when the DSM does not detect movement from the motor.
