Door switch
(Driver side)

—

Driver seat control unit receives door switch signal (driver side/
open) from BCM via CAN communication.

Motors
(Seat sliding, tilt)

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 to 
auto drive positioner control unit via UART communication. The au-
tomatic drive positioner control unit operates each motor for a con-
stant amount.
