 PRECAUTIONS

PRECAUTIONS PFP:00001

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER” EES002WL

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:
● To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.
● Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
● Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

Balancing Wheels EES002WQ

REMOVAL
1. Remove inner and outer balance weights from the wheel.
CAUTION:
Be careful not to scratch the wheel during removal procedures.
2. Using releasing agent, remove double-faced adhesive tape from the wheel.
CAUTION:
● Be careful not to scratch the wheel during removal.

● After removing double-faced adhesive tape, wipe clean traces of releasing agent from the
wheel.
WHEEL BALANCE ADJUSTMENT
NOTE:
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 wheels.
1. Set 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 unbalance value by 1.6 to
determine balance weight that should be used. Select the outer
balance weight with a value closest to the calculated value 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 wheel. SMA054D

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 g = 35 g (1.23 oz.)
37.5 g = 40 g (1.41 oz.)

Revision: December 2006 WT-6 2007 Sentra

 ROAD WHEEL TIRE ASSEMBLY

a. Install balance weight in the position shown.

b. When installing balance weight to wheels, set it into the grooved A
area on the inner wall of the wheel as shown so that the balance
weight center is aligned with the wheel balancer indication posi-
tion (angle). B
CAUTION:
● Always use genuine Nissan adhesion balance weights.

● Balance weights are not reusable; always replace with C

new ones.
● Do not install more than three sheets of balance weight.

WT

G

3. Start wheel balancer again.
4. Install drive-in balance weight on inner side of road wheel in the wheel balancer indication position

5. Start wheel balancer. Make sure that inner and outer residual unbalance values are 5 g (0.18 oz.) each or M
below.
● If either residual unbalance value exceeds 5 g (0.18 oz.), repeat installation procedures.

● Follow the maintenance schedule for tire rotation service inter-

vals. Refer to MA-8, "PERIODIC MAINTENANCE" .
– ⇐: Front
● Do not include the T-type spare tire when rotating tires.
● Tighten wheel nuts to specification.
CAUTION:
● When installing wheels, tighten them diagonally by divid-
ing 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 WEIA0044E

the specification to prevent damage of disc rotor.

Wheel nut : 108 N·m (11 kg-m, 80 ft-lb)

● After rotating the tires, adjust the tire pressure. Refer to WT-29, "Tire" .

Preliminary Check EES002X1

BASIC INSPECTION
1. CHECK ALL TIRE PRESSURES
Check all tire pressures. Refer to WT-29, "Tire" .
Do tire pressures match specifications?
YES >> GO TO 2.
NO >> Adjust tire pressure to specified value.

2. CHECK LOW TIRE PRESSURE WARNING LAMP ACTIVATION

Check low tire pressure warning lamp activation.
Does warning lamp activate for 1 second when ignition switch is turned ON?
YES >> GO TO 3.
NO >> GO TO WT-24, "Low Tire Pressure Warning Lamp Does Not Come On When Ignition Switch Is
Turned On." .

3. CHECK BCM CONNECTOR

1. Disconnect BCM harness connector.
2. Check terminals for damage or loose connection.
3. Reconnect harness connector.
Are BCM connectors damaged or loose?
YES >> Repair or replace damaged parts.
NO >> GO TO 4.

4. CHECK TRANSMITTER ACTIVATION TOOL

Check transmitter activation tool battery.
Is transmitter activation tool battery fully charged?
YES >> Carry out self-diagnosis.
NO >> Replace battery in transmitter activation tool.
Self-Diagnosis EES002X2

DESCRIPTION
During driving, the tire pressure monitoring system receives the signal transmitted from the transmitter
installed in each wheel, and turns on the low tire pressure warning lamp when the tire pressure becomes low.
The control unit (BCM) for this system has pressure judgement and self-diagnosis functions.
FUNCTION
When the tire pressure monitoring system detects low inflation pressure or an internal malfunction, the low tire
pressure warning lamp in the combination meter comes on. The malfunction location is indicated by the low
tire pressure warning lamp flashing and the buzzer sounding.
