*: Tilt does not operates upward when tilt sensor volume is less than 1.2 V, tilt does not operate downward when the sensor value is big-
ger than 3.4 V. Telescopic does not operates backward when telescopic sensor value is less than 0.8 V, telescopic does not operate for-
ward when the sensor value is bigger than 3.4 V.

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 the driver seat control unit via CAN communication and
from the driver seat control unit to the automatic drive positioner control unit via UART communication.

Motors
(Tilt, telescopic)

The automatic drive positioner control unit actuates each motor
according to the operation of the tilt & telescopic switch.

Sensors
(Tilt, telescopic)

—

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.*
