Seat, steering column
and mirror positions set by the driver are memorized in the IMS control
unit by the position sensors. So, those positions can be returned to the
memorized positions by the IMS control switch and keyless control even
when the seat, steering column and mirror positions are changed. (This is
called replay operation). In addition, CAN communication is performed
between power seat control unit and power window. For the sake of safety,
replay is prohibited during driving and replay operation can be stopped
immediately.
