ALUMINUM WHEEL
1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If deformed, remove wheel and check wheel runout.

b. Set dial indicator as shown in the illustration.
c. If the total runout value exceeds the limit, replace aluminum wheel.
STEEL WHEEL (FOR EMERGENCY USE)
1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If deformed, remove wheel and check wheel runout.
a. Remove tire from steel wheel and mount wheel on a tire balance machine.
b. Set two dial indicators as shown in the illustration.
c. Set each dial indicator to “0”.
d. Rotate wheel and check dial indicators at several points around the circumference of the wheel.
e. Calculate runout at each point as shown below.
f. Select maximum positive runout value and the maximum nega- tive value. Add the two values to determine total runout.
CAUTION:
In case a positive or negative value is not available, use the
maximum value (negative or positive) for total runout.
g. If the total runout value exceeds the limit, replace steel wheel. Lateral runout limit (A) : 0.3 mm (0.012 in)
Radial runout limit (B) : 0.3 mm (0.012 in)

REMOVAL
Using releasing agent, remove double-faced adhesive tape from the road wheel.
CAUTION:

Be careful not to scratch the road wheel during removal.

After removing double-faced adhesive tape, wipe clean traces of releasing agent from the road
wheel.
WHEEL BALANCE ADJUSTMENT

If a tire balance machine has adhesion balance weight mode settings and drive-in weight mode setting,
select and adjust a drive-in weight mode suitable for road wheels.
1. Set road wheel on tire balance machine using the center hole as a guide. Start the tire balance machine.
2. When inner and outer unbalance values are shown on the tire balance machine indicator, multiply outer unbalance value by 5/3 to determine balance weight that should be used. Select the outer balance weight
with a value closest to the calculated value above and install it to the designated outer position of, or at the
designated angle in relation to the road wheel.
CAUTION:

Do not install the inner balance weight before installing the outer balance weight.

Before installing the balance weight, be sure to clean the mating surface of the road wheel.
a. Indicated unbalance value × 5/3 = balance weight to be installed
Calculation example:
23 g (0.81 oz) × 5/3 = 38.33 g (1.35 oz)
37.5 g (1.32 oz) bal-
ance weight (closer to calculated balance weight value)
NOTE:
Note that balance weight value must be closer to the calculated
balance weight value.
Example:
36.2
35 g (1.23 oz)
36.3
37.5 g (1.32 oz)
b. Install balance weight in the position shown in the figure.
c. When installing balance weight to road wheels, set it into the grooved area on the inner wall of the road wheel as shown in the
figure so that the balance weight center is aligned with the tire
balance machine indication position (angle).
CAUTION:

Always use genuine NISSAN adhesion balance weights.

Balance weights are non-reusable; always replace with
new ones.

Do not install more than three sheets of balance weight.

d. If calculated balance weight value exceeds 50 g (1.76 oz), install
two balance weight sheets in line with each other as shown in
the figure.
CAUTION:
Do not install one balance weight sheet on top of another.
3. Start tire balance machine again.
4. Install drive-in balance weight on inner side of road wheel in the tire balance machine indication position (angle).
CAUTION:
Do not install more than two balance weights.
5. Start tire balance machine. Make sure that inner and outer resid- ual unbalance values are 5 g (0.2 oz) each or below.
6. If either residual unbalance value exceeds 5 g (0.2 oz), repeat installation procedures.
Tire RotationNES000KZ
1. Follow the maintenance schedule for tire rotation service intervals. Refer to MA-7, "Introduction of Peri-
odic Maintenance" .
2. Do not include the spare tire when rotating the tires.
3. When installing the wheel, tighten wheel nuts to the specified torque.
CAUTION:

When installing wheels, tighten them diagonally by dividing the work two to three times in order
to prevent the wheels from developing any distortion.

Be careful not to tighten wheel nut at torque exceeding the criteria for preventing strain of disc
rotor.
4. Perform the ID registration, after tire rotation. Refer to WT-20, "
ID Registration Procedure" .

ID Registration ProcedureNES000GV
ID REGISTRATION WITH ACTIVATION TOOL
This procedure must be done after replacement of a transmitter, BCM or rotating wheels.
1. Perform “CONSULT-II Start Procedure”. Refer to GI-38, "
CONSULT-II Start Procedure" .
2. Select “AIR PRESSURE MONITOR” on “SELECT WORK ITEM”
3. Touch “WORK SUPPORT” on “SELECT DIAG MODE” screen, and select “ID REGIST”.
4. With the transmitter activation tool (J-45295) pushed against the front-left transmitter position of the air valve, press and hold the
button 5 seconds.
5. Register the IDs in order from FR LH, FR RH, RR RH to RR LH. When ID registration of each wheel has been completed, turn
signal lamp blinks.
6. After completing all ID registrations, press “END” to complete the procedure.
NOTE:
Be sure to register the IDs in order from FR LH, FR RH, RR RH, to RR LH, or the self-diagnostic results dis-
play will not function properly.

Self-DiagnosisNES000GX
DESCRIPTION
During driving, the low tire pressure warning system receives the signal transmitted from the transmitter
installed in each wheel, and gives alarms when the tire pressure becomes low. The control unit (BCM) of this
system has pressure judgment and trouble diagnosis functions.
FUNCTION
When the low tire pressure warning system detects low inflation pressure or another unusual symptom, the
warning lamps in the combination meter comes on. To start the self-diagnostic results mode, ground terminal
of the tire pressure warning check connector. The malfunction location is indicated by the warning lamp flash-
ing and the buzzer sounds.
