PROBLEM SYMPTOMS TABLE
NOTICE:
- When replacing the forward recognition camera, replace it with a new
one. If a forward recognition camera which was installed to another vehicle
is used, the information stored in the forward recognition camera will not
match the information from the vehicle and a DTC may be stored.
- When the forward recognition camera has been replaced with a new one,
make sure to clear all stored vehicle control history of each system and
the forward recognition camera beam axis alignment data.
HINT:
Forward recognition camera beam axis alignment can be performed
by using "One Time Recognition", "Driving Adjustment" or "Camera Axis Adjustment
Value Write".

- When replacing the millimeter wave radar sensor assembly, always replace
it with a new one. If a millimeter wave radar sensor assembly which was
installed to another vehicle is used, the information stored in the millimeter
wave radar sensor assembly will not match the information from the vehicle
and a DTC may be stored.
- When the millimeter wave radar sensor assembly has been replaced with
a new one, it is necessary to perform millimeter wave radar sensor assembly
beam axis alignment and to clear the vehicle control history. Before performing
the Driving Adjustment, make sure to read Before Starting Driving Adjustment.
HINT:
Beam axis alignment of the millimeter wave radar sensor
assembly can be performed using either Triangle Target, Flat Surface Target
or Driving Adjustment.

- When replacing the combination meter assembly, always replace it with
a new one. If a combination meter assembly which was installed to another
vehicle is used, the information stored in it will not match the information
from the vehicle and a DTC may be stored.
- When replacing the forward recognition camera and combination meter
assembly, update the ECU security key.
