ROAD WHEEL
PFP:40300
Inspection
AES000HC
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.
a.
Remove tire from aluminum wheel and mount on a tire balance
machine.
b.
Set dial indicator as shown in the figure.
STEEL 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.
a.
Remove tire from steel wheel and mount wheel on a tire balance
machine.
b.
Set two dial indicators as shown in the figure.
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.
In case a positive or negative value is not available, use the
maximum value (negative or positive) for total runout.
If the total runout value exceeds the limit, replace steel wheel.
Wheel runout (Dial indicator value):
SFA975B
Radial runout = (A+B)/2
Lateral runout = (C+D)/2

ROAD WHEEL TIRE ASSEMBLY
PFP:40300
Balancing Wheels (Bonding Weight Type)
AES000HD
REMOVAL
1.
Remove inner and outer balance weights from the road wheel.
CAUTION:
Be careful not to scratch the road wheel during removal.
2.
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 wheel balancer using the center hole as a guide. Start the tire balance machine.
2.
When inner and outer unbalance values are shown on the wheel balancer indicator, multiply outer unbal-
ance 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.
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) = 40 g (1.41 oz) balance
weight (closer to calculated balance weight value)
Note that balance weight value must be closer to the calculated
balance weight value.
Example:
37.4 = 35 g (1.23 oz)
37.5 = 40 g (1.41 oz)
a.
Install balance weight in the position shown in the figure.
b.
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 wheel
balancer indication position (angle).
CAUTION:
●
Always use genuine Nissan adhesion balance weights.
●
Balance weights are unreusable; always replace with new
ones.
●
Do not install more than three pieces of balance weight.

c.
If calculated balance weight value exceeds 50 g (1.76 oz), install
two balance weight pieces in line with each other (as shown in
the figure).
CAUTION:
Do not install one balance weight piece on top of another.
3.
Start wheel balancer again.
4.
Install drive-in balance weight on inner side of road wheel in the
wheel balancer indication position (angle).
CAUTION:
Do not install more than two balance weights.
5.
Start wheel balancer. Make sure that inner and outer residual
unbalance values are 10 g (0.35 oz) each or below.
●
If either residual unbalance value exceeds 10 g (0.35 oz), repeat installation procedures.
Wheel balance (Maximum allowable unbalance):
Rotation
AES000MY
●
After rotating the tires, adjust the tire pressure.
●
Retighten the wheel nuts when the vehicle has been driven for
1,000 km (600 miles) (also in cases of a flat tire, etc.).
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.
Maximum allowable
unbalance
Dynamic (At rim flange)
10 g (0.35 oz) (one side)
Static (At rim flange)
20 g (0.71 oz)

TRANSMITTER
A sensor-transmitter integrated with a valve is installed on a wheel,
and transmits a detected air pressure signal in the form of a radio
wave.

ANTENNA
Receives the radio wave signal transmitted by the transmitter.
LOW TIRE PRESSURE WARNING CONTROL UNIT
Reads the radio wave signal received by the antenna, and controls
the warning lamp and the buzzer operations as shown below. It also
has a judgement function to detect a system malfunction.
DISPLAY UNIT
Displays the air pressure of each tire.
●
After the ignition switch is turned ON, the pressure values are
not be displayed until the data of each wheel stabilizes.

CAN COMMUNICATION
PFP:23710
System Description
AES000OJ
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 speed 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 independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

ID REGISTRATION WITH ACTIVATION TOOL
This procedure must do after replacing transmitter or low tire pressure warning control unit.
1.
Turn ignition switch "OFF".
2.
Connect CONSULT-II and CONSULT-II CONVERTER to data link connector.
3.
Touch “AIR PRESSURE MONITOR”, “WORK SUPPORT” and “ID REGIST”.
NOTE:
If "AIR PRESSURE MONITOR" is not indicated, go to
GI-39, "CONSULT-II Data Link Connector (DLC)
4.
With the activation tool (J-45295) pushed against the front-left
transmitter position of the tire air valve, press and hold the but-
ton for 5 seconds.
5.
Register the IDs in order from FR LH, FR RH, RR RH or RR LH. When ID registration of each wheel has
been completed, a buzzer sounds and hazard warning 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.
