THE ALIGNMENT PROCESS
IMPORTANT:
Use only the alignment specifications listed in this Service Manual.

When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or
minus, Go/No Go). Do NOT use these indicators.
–The alignment specifications programmed into your machine that operate these indicators may not be cor-
rect.
–This may result in an ERROR.

Some newer alignment machines are equipped with an optional “Rolling Compensation” method to “com-
pensate” the sensors (alignment targets or head units). DO NOT use this “Rolling Compensation”
method.
–Use the “Jacking Compensation Method”. After installing the alignment targets or head units, raise the
vehicle and rotate the wheels 1/2 turn both ways.
–See Instructions in the alignment machine you're using for more information on this.
INSPECTION OF CAMBER, CASTER AND KINGPIN INCLINATION ANGLES

Camber, caster, kingpin inclination angles cannot be adjusted.

Before inspection, mount front wheels onto turning radius gauge. Mount rear wheels onto a stand that has
same height so vehicle will remain horizontal.
Using a CCK Gauge
Install the CCK gauge attachment [SST: KV991040S0 ( – )] with the following procedure on wheel, then
measure wheel alignment.
1. Remove three wheel nuts, and install the guide bolts to hub bolt.
2. Screw the adapter into the plate until it contacts the plate tightly.
3. Screw the center plate into the plate.
4. Insert the plate assembly on the guide bolt. Put the spring in,
and then evenly screw the three guide bolt nuts. When fastening
the guide nuts, do not completely compress the spring.
5. Place the dent of alignment gauge onto the projection of the
center plate and tightly contact them to measure.
CAUTION:

If camber, caster, or kingpin inclination angle is outside
the standard, check front suspension parts for wear and
damage. Replace suspect parts if a malfunction is
detected.

Kingpin inclination angle is reference value, no inspec-
tion is required.

On-Vehicle Inspection NES000IQ
Make sure the mounting conditions (looseness, back lash) of each component and component conditions
(wear, damage) are normal.
INSPECTION OF UPPER LINK BALL JOINT END PLAY
1. Set front wheels in a straight-ahead position. Do not depress brake pedal.
2. Place an iron bar or similar tool between transverse link and steering knuckle.
3. Measure axial end play by prying it up and down.
CAUTION:
Be careful not to damage ball joint boot. Do not damage the installation position by applying
excessive force.
SHOCK ABSORBER INSPECTION
Check for oil leakage, damage and breakage of installation positions.
Wheel Alignment InspectionNES000IR
DESCRIPTION
Measure wheel alignment under unladen conditions.
NOTE:
“Unladen conditions” means that fuel, engine coolant, and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
PRELIMINARY CHECK
Check the following:
1. Check tires for improper air pressure and wear.
2. Check road wheels for runout. Refer to WT-6, "
ROAD WHEEL" .
3. Check wheel bearing axial end play. Refer to FAX-5, "
WHEEL BEARING INSPECTION" .
4. Check transverse link ball joint axial end play. Refer to FSU-32, "
INSPECTION AFTER REMOVAL" .
5. Check shock absorber operation.
6. Check each mounting part of axle and suspension for looseness and deformation.
7. Check each of suspension member, shock absorber, upper link and transverse link for cracks, deforma-
tion and other damage.
8. Check vehicle height (posture).
GENERAL INFORMATION AND RECOMMENDATIONS

A four-wheel thrust alignment should be performed.
–This type of alignment is recommended for any NISSAN/INFINITI vehicle.
–The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel is
centered.
–The alignment rack itself should be capable of accepting any NISSAN/INFINITI vehicle.
–The rack should be checked to ensure that it is level.

Make sure the machine is properly calibrated.
–Your alignment equipment should be regularly calibrated in order to give correct information.
–Check with the manufacturer of your specific equipment for their recommended Service/Calibration
Schedule.Axial end play : 0 mm (0 in)

Height sensor signal from height sensor connected to AFS control unit

Swivel position sensor signal from swivel position sensor built into both right and left swivel actuators con-
nected to AFS control unit
In response to the state of control, AFS control unit switches commands of AFS off indicator signal sent to uni-
fied meter and A/C amp. via CAN communication; and then turns on/off or blinks AFS off indicator lamp built in
the combination meter.
AFS (ADAPTIVE FRONT-LIGHTING SYSTEM)
AFS increases viewability of cornering direction by changing light axis automatically to the direction of travel
with low beam headlamps during vehicle's cornering.
AFS switch allows AFS function to be stopped.
AFS control unit determines the current vehicle conditions by each received signals, and sends commands to
the low beam headlamp to swivel. With the headlamps (HIGH/LOW) illuminated, the AFS switch on, engine
running and the A/T select lever in any position but range P or range R, the low beam headlamps are opera-
tive by AFS control unit commands.
As the steering wheel is turned to the left (right), the left (right) low beam headlamp will automatically swivel
angle in accordance with the steering angle and vehicle speed, and stop the operation when the steering
wheel is returned to the straight-ahead position.
Swivel operation allows drive signal to be sent to the swivel actuator on the side that AFS control unit is actu-
ated. Step motor built in swivel actuator adjusts low beam projector of headlamp to swivel angle that matches
drive signal. Swivel position sensor built in swivel actuator detects swivel angle and transmits a swivel position
sensor signal to the AFS control unit. AFS control unit monitors if swivel operation is performed normally via
swivel position sensor signal.

Swivel operation
*1: Included high beam illuminated.
*2: The swivel operates when running at approx. 25 km/h (15.5 MPH). When swivel operation is started, it works on until vehicle
stops.
*3: The low beam headlamps perform small movements when AFS control unit detects start of the engine. This is normal with ini-
tialization of swivel actuator by AFS control unit.Low beam
