Motors
(Seat sliding, tilt, 
telescopic)

Driver seat control unit operates the seat sliding motor, which recog-
nizes that the driver side door is opened with ignition switch OFF. 
Driver seat control unit then requests the operations of tilt motor and 
telescopic motor to auto drive positioner control unit via UART com-
munication. The automatic drive positioner control unit operates 
each motor for a constant amount.
