AUTOMATIC DRIVE POSITIONER SYSTEM
MEMORY FUNCTION : Component Parts Location
INFOID:0000000004831090
Order Input Output Control unit condition
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.
2— Motors
(seat, pedal adjusting,
tilt, 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, tilt, 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-
torDriver 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.

AUTOMATIC DRIVE POSITIONER SYSTEM
ENTRY ASSIST FUNCTION : Component Parts Location
INFOID:0000000004831092
Order Input Output Control unit condition
1 Door switch/Ignition
switch —
Driver seat control unit receives the signals of ignition switch signal
and front door switch from BCM via CAN communication.
2 —
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.

SLIDING MOTOR
DescriptionINFOID:0000000001735528
• The sliding motor LH is installed to the seat cushion frame.
• The sliding motor LH is installed with the driver seat control unit.
• The seat is slid forward/backward by changing the rotation direction of sliding motor LH.
Component Function CheckINFOID:0000000001735529
1. CHECK FUNCTION
1. Select “SEAT SLIDE” in “Active test” mode with CONSULT-III.
2. Check the sliding motor LH operation.
Is the operation of relevant parts normal?
YES >> INSPECTION END
NO >> Perform diagnosis procedure. Refer to ADP-87, "
DiagnosisProcedure".
Diagnosis ProcedureINFOID:0000000001735530
1. CHECK SLIDING MOTOR LH POWER SUPPLY
1. Turn the ignition switch ACC.
2. Perform “Active test” (“SEA T SLIDE”) with CONSULT-lll
3. Check voltage between driver s eat control unit harness connec-
tor and ground.
Is the inspection result normal?
YES >> Replace sliding motor LH. (Built in seat slide cushion frame.)
NO >> GO TO 2
