INFOID:0000000003935461

MEMORY FUNCTION : System Description

INFOID:0000000003935462

OUTLINE

The driver seat control unit can store the optimum driving positions (seat, pedal assembly 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 Owner’s Manual.

OPERATION PROCEDURE

1.

Turn ignition switch ON

2.

Press desired memory switch for more than 0.5 second.

3.

Front seat LH, pedal assembly 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.

Item

Function

Door mirror motor (LH/RH)

Move the outside mirror face up/down and left/right.

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, pedal adjusting,
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, pedal adjust-
ing, door mirror)

—

Driver seat control unit judges the operating seat position with each
seat sensor input. The positions of the adjustable pedals 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.
