OUTLINE

The driver seat control unit can store the optimum driving positions (seat, steering column and door mirror
position) for 2 people. If the front seat position is changed, one-touch (pressing desired memory switch for
more than 0.5 second) operation allows changing to the other driving position.
NOTE:
Further information for the memory storage procedure. Refer to  

ADP-10, "MEMORY STORING : Description"

. 

OPERATION PROCEDURE

1.

Turn ignition switch ON

2.

Satisfy all of the following items. The memory function is not performed if these items are not satisfied.

However, the memory operation can be performed for 45 seconds after opening the driver door (driver door switch OFF 

→

 ON) even if

the IGN position is in OFF position.

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 auto drive positioner control unit via UART communication after all 
motors stop. The auto driving positioner control unit illuminates the 
memory indicator for 5 seconds.
