3. Select “Camera Cont.” of Confirmation/ Adjustment mode, and then set to “Fine Tuning of Birds-Eye View”
mode.
4. Select left and right cameras by pressing the “CAM ERA” switch, and perform the following confirmation.
- Check that target line 1 is aligned with the marker on the screen. Overlap the line aligned to the marker
with the upper/lower switches if necessary.
- Check if there is a difference between target lines 2 between cameras. Adjust target lines 2 to be straight
lines by operating the center dial and left/right switches if necessary.
CAUTION:
 Never adjust the front camera and rear camer a. Only adjust the right and left cameras.
 Operate the center dial slowly because the ch anging of the screen takes approximately 1 sec-
ond.
Simplified target line adjustment method
5. Adjust left and right cameras. Check that the difference between target line 1 and the marker on the
screen, and between target lines 2 is solved.
NOTE:
 It can be initialized to the NISSAN factory default c ondition with “Initialize Camera Image Calibration” of
“Calibrating Camera Image”.
 The adjustment value is cancelled on this mode by performing “Initialize Camera Image Calibration”.
Is the difference corrected?
YES >> Finish the writing to around view monito r control unit by pressing “ENTER” switch.
NO >> GO TO 5.

Preparation of target line
1. Hang a string with a weight as shown in the figure. Put the points FM0, RM0 (mark) on the ground at the
center of the vehicle front end and rear end with white packing tape or a pen.
2. Route the vinyl string under the vehicle, and then pull and fix it on the point approximately 1.0 m (39.9 in)
to the front and rear of the vehicle through the points FM0 and RM0 using packing tape.

1.5 m (59 in) on both sides with packing tape.
5. Put the points FL, FR, RL, and RR (mark) to both right and left [vehicle width / 2 + 30 cm (11.8 in)] from the
points FM and RM.

6. Draw the lines of the points FL – RL and FR – RR with vinyl string, and fix it with packing tape.
7. Put a mark on the center of each axle, draw vertical lines to the lines of the points FL – RL and FR – RR
from the marks on the center of t he axle using a triangle scale, and then fix the lines using packing tape.

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".
