DETAIL FLOW

Order	Input	Output	Control unit condition
1	Front door switch LH	-	Driver seat control unit receives front door switch LH signal (open) from BCM via CAN communication.
2	-	Motors [seat sliding LH, tilt)]	Driver seat control unit operates the seat sliding motor LH, which recognizes that the driver side door is opened with ignition switch OFF. Driver seat control unit then requests the operations of tilt motor to automatic drive positioner control unit via CAN communication. The automatic drive positioner control unit operates each motor for a constant amount.
