ENTRY ASSIST FUNCTION : System DescriptionINFOID:0000000006248312
The seat is in the exiting position when following condition is satisfied, the seat returns from exiting position to
the previous driving position.
NOTE:
 This function is set to ON before delivery (initial setting).
 Further information for the system setting procedure. Refer to ADP-54, "
SYSTEM SETTING : Description".
OPERATION PROCEDURE
1. Turn ignition switch ACC.
Transmission A/T
CUNSULT-III Not connected
Item Request status
Order Input Output Control unit condition
1 Door switch
(Driver side)
—Driver seat control unit receives door switch signal (driver side/
open) from BCM via CAN communication.
2— Motors
(Sliding, tilt)Driver seat control unit operates the seat sliding motor, which recog-
nizes that the driver side door is opened with ignition switch OFF.
Driver seat control unit then requests the operations of tilt motor to
auto drive positioner control unit via UART communication. The au-
tomatic drive positioner control unit operates each motor for a con-
stant amount.
3 Sensor
(Sliding, tilt) —Each sensor monitors the operating positions of seat and steering,
and then stops the operation of each motor when each part reaches
the recorded address.

1 Ignition switch — Driver seat control unit receives the signals of [ignition switch signal]
from BCM via CAN communication.
2— Motors
(Sliding, tilt)Driver side control unit operates the sliding motor when the operating
conditions are satisfied and requests the operations of tilt motor to
automatic drive positioner control unit via UART communication. The
automatic drive positioner operates each motor.
3 Sensors
(Sliding, tilt) —Each sensor monitors the operating positions of seat and steering,
and then stops the operation of each motor when each part reaches
the recorded address.
