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”.

●

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.

●

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"

●

Low tire pressure warning lamp flashes 1min, then turns ON when occurring any malfunction except low
tire pressure. Delete the memory with CONSULT-II, or register the ID to turn low tire pressure warning
lamp OFF. Refer to

WT-26, "ERASE SELF-DIAGNOSIS"

WT-26, "ID Registration Procedure"

●

ID registration is required when replacing or rotating wheels, replacing transmitter or BCM. Refer to

WT-

26, "ID Registration Procedure"

●

Replace grommet seal, valve core and cap of the transmitter in TPMS every tire replacement by reaching
wear limit of tire.

TIRE PRESSURE MONITORING SYSTEM

Revision: 2006 July

2007 Murano

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.

REMOTE KEYLESS ENTRY RECEIVER

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

BCM (BODY CONTROL MODULE)

The BCM (1) reads the air pressure signal received by the remote
key-less entry receiver, and controls the low tire pressure warning
lamp and the buzzer operations. It also has a judgment function to
detect a system malfunction.

LOW TIRE PRESSURE WARNING LAMP

The combination meter receives tire pressure status from the BCM
using CAN communication. When a low tire pressure condition is
sensed by the BCM, the low tire pressure warning lamp of combina-
tion meter is activated.

Low Tire Pressure Warning Lamp

*1: Standard air pressure is for 230 kPa (2.3 kg/cm

, 33 psi) vehicles.

*2: Warning lamp turns ON when occurring a malfunction in CAN communication lines.

VEHICLE INFORMATION DISPLAY

Displays the air pressure of each tire. After the ignition switch is turned ON, the pressure values are not dis-
played until the data of each wheel stabilizes.

TIRE PRESSURE WARNING CHECK SWITCH

The following item can be checked by grounding the tire pressure
warning check switch (1) harness connector terminal.

●

The low tire pressure warning lamp in the combination meter will
flicker according to the self-diagnostic results.

SEIA0434E

Condition

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.

Component parts

Function

BCM

A tire pressure monitoring system is built into the BCM, and the BCM monitors tire pressures.

Transmitter

Converts tire pressure signals to radio wave signals.

Remote keyless entry receiver

Receives radio wave signals converted from tire pressure signals.

Tire pressure warning check
switch

Allows a mode to be switched to a diagnosis mode.

Turn signal lamp

ID registration of each wheel has been completed, turn signal lamp flashes two times.

Combination meter

Controls a low tire pressure warning lamp, turn signal lamp, and buzzer by signals from the unified
meter and A/C amp.

Low tire pressure warning lamp

Illuminates if malfunction is detected in electrical system of tire pressure monitoring system.

Unified meter and A/C amp.

Transmits the vehicle speed signal via CAN communication to BCM.
Receives the tire pressure signal via CAN communication from BCM.

Display control unit

Receives the tire pressure data signal via CAN communication from BCM.

How to Perform Trouble Diagnosis

NES000E1

BASIC CONCEPT

●

To perform trouble diagnosis, it is the most important to have understanding about vehicle systems (con-
trol and mechanism) thoroughly.

●

It is also important to clarify customer complaints before inspec-
tion.
First of all, reproduce symptoms, and understand them fully.
Ask customer about his/her complaints carefully. In some cases,
it will be necessary to check symptoms by driving vehicle with
customer.

CAUTION:

Customers are not professional. It is dangerous to make an
easy guess like “maybe the customer means that...,” or
“maybe the customer mentions this symptom”.

●

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
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-
out any symptom diagnosis, you cannot judge if malfunctions
have actually been eliminated.

●

After completing diagnosis, always erase diagnostic memory.
Refer to

WT-26, "ERASE SELF-DIAGNOSIS"

●

For intermittent malfunctions, move harness or harness connec-
tor by hand. Then check for poor contact or reproduced open circuit.

INTRODUCTION

●

Before troubleshooting, verify customer complaints.

●

If a vehicle malfunction is difficult to reproduce, harnesses, harness connectors or terminals may be mal-
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.
