 PRECAUTIONS

PRECAUTIONS PFP:00001

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER” NES000ES

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.
Precautions NES000L7

● Before connecting or disconnecting the BCM harness con-

nector, turn ignition switch “OFF” and disconnect the bat-
tery cable from the negative terminal. Battery voltage is
applied to BCM even if ignition switch is turned “OFF”.

SEF289H

● When connecting or disconnecting pin connectors into or

from BCM, take care not to damage pin terminals (bend or
break).
When connecting pin connectors make sure that there are
not any bends or breaks on BCM pin terminals.

SEF291H

● Before replacing BCM, perform control unit input/output

signal inspection and make sure whether BCM functions
properly or not. Refer to WT-18, "BCM Input/Output Signal
Reference Values" .

 TIRE PRESSURE MONITORING SYSTEM

TIRE PRESSURE MONITORING SYSTEM PFP:40720

System Description NES000FJ

DESCRIPTION
During driving, the tire pressure monitoring system receives the signal transmitted from the transmitter
installed in each wheel, when the tire pressure becomes low. The control unit (BCM) of this system has pres-
sure judgment and trouble diagnosis functions.
Function
When the tire pressure monitoring 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.
TRANSMITTER
A sensor-transmitter (1) integrated with a valve is installed on a
wheel (2), and transmits a detected air pressure signal in the form of
a radio wave.
:Outside

SEIA0768E

REMOTE KEYLESS ENTRY RECEIVER

The remote keyless entry receiver (1) receives the air pressure sig-
nal transmitted by the transmitter in each wheel.

SEIA0755E

BCM (BODY CONTROL MODULE)

The BCM (1) reads the air pressure signal received by the remote

Can Communication NES000E0

SYSTEM DESCRIPTION
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-44, "TROUBLE DIAGNOSIS" .

 TROUBLE DIAGNOSES

TROUBLE DIAGNOSES PFP:00004

A
How to Perform Trouble Diagnosis NES000E1

BASIC CONCEPT
● To perform trouble diagnosis, it is the most important to have understanding about vehicle systems (con- B
trol and mechanism) thoroughly.
● It is also important to clarify customer complaints before inspec-
tion.
First of all, reproduce symptoms, and understand them fully. C
Ask customer about his/her complaints carefully. In some cases,
it will be necessary to check symptoms by driving vehicle with
customer. D
CAUTION:
Customers are not professional. It is dangerous to make an
easy guess like “maybe the customer means that...,” or WT
“maybe the customer mentions this symptom”.
SEF233G

F
● It is essential to check symptoms right from the beginning in
order to repair malfunctions completely.
For intermittent malfunctions, reproduce symptoms based on
interview with customer and past examples. Do not perform G
inspection on ad hoc basis. Most intermittent malfunctions are
caused by poor contacts. In this case, it will be effective to shake
suspected harness or connector by hand. When repairing with- H
out any symptom diagnosis, you cannot judge if malfunctions
have actually been eliminated.
● After completing diagnosis, always erase diagnostic memory. I
Refer to WT-26, "ERASE SELF-DIAGNOSIS" . SEF234G

● For intermittent malfunctions, move harness or harness connec-

tor by hand. Then check for poor contact or reproduced open circuit. J
INTRODUCTION
● Before troubleshooting, verify customer complaints.
● If a vehicle malfunction is difficult to reproduce, harnesses, harness connectors or terminals may be mal- K
functioning. Hold and shake these parts to make sure they are securely connected.
● When using a circuit tester to measure voltage or resistance of each circuit, be careful not to damage or
deform connector terminals. L

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) Þ 40 g (1.41 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:
37.4 Þ 35 g (1.23 oz)
37.5 Þ 40 g (1.41 oz)
SMA054D

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
