MEMORY FUNCTION : System Description

INFOID:0000000009720639

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) oper-
ation allows changing to the other driving position.
NOTE:
Further information for the memory storage procedure. Refer to  

ADP-9, "MEMORY STORING : Description"

. 

OPERATION PROCEDURE

1.

Turn ignition switch ON

2.

Shift position P position

3.

Press desired memory switch.

4.

Driver seat, steering and door mirror will move to the memorized position.

OPERATION CONDITION

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 ignition switch position is in OFF position.

Memory switch

—

The memory switch signal is inputted to the driver seat control unit 
when memory switch 1 or 2 is operated.

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 
while either of the motors is operating. The driver seat control unit il-
luminates 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. Driver seat control unit 
stops the operation of each motor when each part reaches the record-
ed address.

4

—

Memory switch Indica-
tor

Driver seat control unit requests the illumination of memory indicator 
after all motors stop. The driver seat control unit illuminates the mem-
ory indicator for 5 seconds.
