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.

 Downsize and weight reduction is aimed. IC for detection portion and magnet for sensor rotor are adopted.
 Power supply is supplied to detection portion so that magnetic field
line is read. Magnetic field that is detected is converted to current
signal.
 When sensor rotor rotates, magnetic field changes. Magnetic field
change is converted to current signals (rectangular wave) and is
transmitted to ABS actuator and electric unit (control unit). Change
of magnetic field is pr oportional to wheel speed.
Stop Lamp SwitchINFOID:0000000006222563
Detects the operation status of brake pedal and transmits converted electric signal to ABS actuator and elec-
tric unit (control unit).
Steering Angle SensorINFOID:0000000006222564
Detects the following information and transmits steering angle signal to ABS actuator and electric unit (control
unit) via CAN communication.
 Steering wheel rotation amount
 Steering wheel rotation angular velocity
 Steering wheel rotation direction
Yaw Rate/Side/Decel G sensorINFOID:0000000006222565
Calculates the following information that affects the v ehicle and transmits a signal to ABS actuator and electric
unit (control unit) via communication lines.
 Vehicle rotation angular velocity (yaw rate signal)
 Vehicle lateral acceleration (side G signal) / longitudinal acceleration (decel G signal)
Brake Fluid Level SwitchINFOID:0000000006222566
Detects the brake fluid level in reservoir tank and trans mits converted electric signal from ABS actuator and
electric unit (control unit), when brake fluid level is the specified level or less.
Parking Brake SwitchINFOID:0000000006222567
Detects the operation status of parking brake switch and transmits converted electric signal from combination
meter to ABS actuator and electric unit (control unit).
VDC OFF SwitchINFOID:0000000006222568
 VDC OFF switch is integrated in SNOW MODE / TOW MODE / VDC OFF switch assembly (2WD models) or
4WD switch assembly (4WD models).
 The operation of the VDC OFF switch enables the arbi trary switching of the VDC function between stop sta-
tus and standby status. The status of the function is indicated by the VDC OFF indicator lamp. (ON: Non-
operational status, OFF: Standby status)
- VDC function NOTE:
Brake limited slip differentia l (BLSD) control operates.
- TCS function
 VDC OFF indicator lamp turns OFF (standby status) when the engine is started again after it is stopped once while VDC OFF indicator lamp is ON (non-operational status).

 EBD function is expanded and developed from conventi onal ABS function and corrects rear wheel brake
force to appropriate level by electronic control according to load weight (number of passengers).
 During braking, control unit portion compares slight slip on front and rear wheels by wheel speed sensor signal, transmits drive sig-
nal to actuator portion when rear wheel slip exceeds front wheel
slip for the specified value or more, and controls rear wheel brake
force (brake fluid pressure) so t hat increase of rear wheel slip is
prevented and slips on front wheel and rear wheel are nearly
equalized. ABS control is applied when slip on each wheel
increases and wheel speed is the threshold value of ABS control or
less.
 CONSULT-III can be used to diagnose the system diagnosis.
 Fail-safe function is adopted. When a malfunction occurs in EBD function, the control is suspended for VDC function, TCS function,
ABS function, EBD function, hill start assist function and brake lim-
ited slip differential (BLSD) func tion. The vehicle status becomes
the same as models without VDC function, TCS function, ABS
function, EBD function, hill start assist function and brake limited
slip differential (BLSD) function. Refer to BRC-25, "
Fail-safe".

Suspend a weight from a string (1) at
tached to its end at the point (B)
leftward from the ICC target board center (A).
>> GO TO 3.
3.SETTING ICC TARGET BOARD
1. Suspend a thread with weight on tip from the center of the front and rear bumpers. Then, mark the center
points on the ground as each weight point.
2. Link the front and rear bumpers center point s marked on the ground and extend a straight line ahead.
Then mark a point 3.9 m (12.8 ft) position ahead of t he front bumper. Then, adjust the position of the ICC
target board so that the weight comes on the top of the marked point [3.9 m (12.8 ft) position ahead of the
front bumper] and face to the vehicle.
3. Remove the thread suspended to the left side of I CC target board and suspend a thread with weight on tip
on the center of the ICC ta rget board. Then mark the poi nt of weight on the ground.
4. Pivot the edge of the ICC target board 25 ° (a) to either side.
NOTE:
Approx. 90 mm (3.54 in) (b) shift rates the 25 ° (a) movement.
>> GO TO 4.
4.CHECK THE ICC TARGET BOA RD INSTALLATION POSITION
Check that the ICC target board (1) is located as shown in the figure.
