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.
UART communication line malfunction and CAN communication line malfunction are detected, the door mirror
cannot be operated.
