CALIBRATING CAMERA IMAGE (AROUND VIEW MONITOR)
DescriptionINFOID:0000000006216246
 Perform the calibration and perform the writing to the around view monitor control unit when removing and
replacing each camera, removing the camera mounting part s (front grille, door mirror, etc.) and replacing the
around view monitor control unit.
 Align the white lines on the road near the vehicle at the boundary of each camera image by this camera cal-
ibration. The white lines far from the vehicle may not be aligned at the boundary of each camera image. The
farther the line, the greater the difference is.
Work ProcedureINFOID:0000000006216915
Calibration flowchart
Following the flowchart shown in the figure, perform the calibration.
NOTE:
In the un-match display, the un-match camera position is indicated
as “ ” on the birds-eye view.

Check that there is the un-match display in any camera.
Is the un-match display visible?
YES >> GO TO 2.
NO >> GO TO 4.
2.CHECK THAT AROUND VIEW MONITOR CONTROL UNIT IS REPLACED
Check that the around view monitor control unit is replaced.
Is the around view monitor control unit replaced?
YES >> GO TO 3.
NO >> GO TO 5.
3.RELEASE UN-MATCH DISPLAY (PERFORM ONLY WHEN THE AROUND VIEW MONITOR CONTROL
UNIT IS REPLACED)
1. Select “Camera Cont.” of Confirmation/ Adjust ment mode, and then set to “Calibrating Camera Image”
mode.
2. Press the “ENTER” switch of the multifunction switch on each screen of “Rear Camera”, “Front Camera”, “Dr-Side Camera”\
,
“Pass-Side Camera”.
CAUTION:
 Do never operate the center dial and up/down/left/right
switches. Only press the “ENTER” switch.
 Never perform “Initialize Camera Image Calibration”.
3. Display the around view monitor screen, and check that there is
no malfunction such as a difference between each camera
image.
Is there a malfunction?
YES >> Calibration end
NO >> GO TO 1.
4.PERFORM SIMPLIFIED CONFIRMATION/ADJUSTM ENT BY “FINE TUNING OF BIRDS-EYE VIEW”
1. Put target line 1 on the ground beside each axle using packing tape, etc.
2. Put target lines 2 equal to the vehicle total length + approximately 1.0 m (39.3 in) from the vehicle side
(right and left) at approximately 30 cm (11.8 in) away from the vehicle (make the line as parallel with the
vehicle as possible)

6.PERFORM “FINE TUNING OF BIRDS-EYE VIEW”
This mode is designed to align the boundary between each camera image that could not be aligned in the
“Calibrating Camera Image” mode.
1. Select “Camera Cont.” of “Confirmation/ Adjustm ent” mode, and then set to “Fine Tuning of Birds-Eye
View” mode.
2. Operate the center dial and upper/l ower/left/right switch to over-
lap the marker on the screen and the target lines on the ground.

DTC/CIRCUIT DIAGNOSIS
U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000006216248
CAN (Controller Area Network) is a serial communication line for real-time application. It is an on-vehicle mul-
tiplex communication line with high data communication s peed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independently). In CA N communication, control units are connected with 2
communication lines (CAN-H, CAN-L) allowing a high rate of information transmission with less wiring. Each
control unit transmits/receives data but selectively reads required data only.

CAN COMMUNICATION SYSTEM : CAN Communica-
tion Signal Chart".
