1
Memory switch
—
The memory switch signal is inputted to the automatic drive positioner
control unit when memory switch 1 or 2 is operated.
Memory switch signal is input to driver seat control unit via UART
communication.

Motors
(Seat, Steering,
door mirror)
Driver seat control unit operates each motor of seat when it recogniz-
es the memory switch pressed for 0.5 second or more and requests
each motor operation to automatic drive positioner control unit via
UART communication. The automatic drive positioner control unit op-
erates each motor.
Memory switch Indica-
tor
Driver seat control unit requests the flashing of memory indicator to
automatic drive positioner control unit via UART communication while
either of the motors is operating. The automatic drive positioner con-
trol unit illuminates the memory indicator.
3
Sensors
(Seat, steering col-
umn, door mirror)
—
Driver seat control unit judges the operating seat position with each
seat sensor input. The positions of the steering column and outside
mirror are monitored with each sensor signal that is input from auto
drive positioner control unit via UART communication. Driver seat
control unit stops the operation of each motor when each part reach-
es the recorded address.
4
—
Memory switch Indica-
tor
Driver seat control unit requests the illumination of memory indicator
to automatic drive positioner control unit via UART communication af-
ter all motors stop. The automatic drive positioner control unit illumi-
nates the memory indicator for 5 seconds.
