AUTOMATIC DRIVE POSITIONER SYSTEM
Tilt steering wheel
Door Mirror
NOTE:
The door mirrors can be operated manually when ignition switch is in either ACC or ON position. The ignition
switch signal (ACC/ON) is transmitted from BCM to t he driver seat control unit via CAN communication and
from the driver seat control unit to the automatic drive positioner control unit via UART communication.
Order Input Output Control unit condition
1 Pedal adjusting switch — The pedal adjusting switch signal is input to the automatic drive
positioner control unit when the pedal adjusting switch is operat-
ed.
2—Motor The automatic drive positioner control unit actuates the motor ac-
cording to the operation of the pedal adjusting switch signal from
the driver seat control unit.
3 Sensor
(forward, backward) —The automatic drive positioner control unit recognizes any oper-
ation limit of each actuator via each sensor and will not operate
the actuator anymore at that time.
Order Input Output Control unit condition
1 ADP steering switch — The ADP steering switch signal is input to the automatic drive po-
sitioner control unit when the ADP steering switch is operated.
2—Motor The automatic drive positioner control unit actuates the tilt motor
according to the operation of the ADP steering switch signal.
3 Sensor
(upward, downward) —The automatic drive positioner control unit recognizes any oper-
ation limit of each actuator via each sensor and will not operate
the actuator anymore at that time.
Order Input Output Control unit condition
1 Door mirror remote
control switch —The door mirror remote control switch signal is inputted to the au-
tomatic drive positioner control unit when the door mirror remote
control switch is operated.
2— Motors
(Door mirror motor)The automatic drive positioner control unit actuates each motor
according to the operation of the door mirror remote control switch.
