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 sheets of balance weight.

c. 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 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 7.5 g (0.26 oz) each or below.

If either residual unbalance value exceeds 7.5 g (0.26 oz), repeat installation procedures.
Wheel balance (Maximum allowable unbalance):
Tire RotationAES000ON

After rotation 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:

Do not include the T-type spare tire when rotating the tires.

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
unbalanceDynamic (At rim flange) 7.5 g (0.26 oz) (one side)
Static (At rim flange) 20 g (0.70 oz)

CAN COMMUNICATIONPFP:23710
System DescriptionAES000OQ
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.
Refer to LAN-6, "
CAN COMMUNICATION" .

NOTE:
Each OUTPUT terminal transistor is activated at 10 ms intervals. Therefore after switch is turned ON, electri-
cal loads are activated with time delay. But this time delay is so short that it cannot be detected by human
senses.
Operation Mode
Combination switch reading function has operation modes shown below.
1. Normal status
–When BCM is not in sleep status, OUTPUT terminals (1-5) each turn ON-OFF every 10 ms.
2. Sleep status
–When BCM is in sleep status, transistors of OUTPUT (1 and 5) stop the output, and BCM enters low cur-
rent consumption mode. OUTPUT (2, 3, and 4) turn ON-OFF every 10 ms, and only input from light switch
system is accepted.
