Driver seat control unit receives the signals of ignition switch signal
and front door switch from BCM via CAN communication.

Motors (sliding, tilt) Driver seat control unit operates the sliding motor when the operating
conditions are satisfied. Driver seat control unit then requests the op-
eration of the tilt motor to the automatic drive positioner control unit
via UART communication. The automatic drive positioner control unit
operates the motor for a constant amount.
Sensors (sliding, tilt) —Sensors monitor the operating positions of seat and steering wheel
and then stops the operation of each motor when each part reaches
the recorded address.
