1 Front door switch LH — Driver seat control unit receives front door switch LH signal (open)
from BCM via CAN communication.
2— Motors (seat sliding,
tilt)Driver seat control unit operates the seat sliding motor, which recog-
nizes that the front door LH is opened with ignition switch OFF. Driv-
er seat control unit then requests the operation 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.

B2128 UART COMMUNICATION LINE
B2128 UART COMMUNICATION LINE
DescriptionINFOID:0000000003775544
Driver seat control unit performs UART communication with the automatic drive positioner control unit using 2
communication lines, TX and RX line. Driver seat cont rol unit receives the operation signals of pedal adjusting
switch, door mirror remote control switch, set switch and memory switch and the position signals of adjustable
pedal sensor and door mirror sensor from the automatic drive positioner control unit and transmits the opera-
tion request signal.
