Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NES000L3
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.
PrecautionsNES000L5

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-19, "
Control Unit Input/Output
Signal Standard" .

Service Notice or PrecautionsNES000L6

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, "
How to Erase Self- diagnostic Results" , WT-20, "ID Registration Procedure" .

ID registration is required when replacing or rotating wheels, replacing transmitter or BCM. Refer to WT-
20, "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 FX35/FX45
BCM (BODY CONTROL MODULE)
The BCM 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 combination meter low tire pressure warn-
ing lamp is activated.
Low Tire pressure Warning Lamp Indication
Note 1: Standard air pressure is for 220 kpa (2.2 kg/cm2 , 32 psi) vehicles.
RUN-FLAT TIRE 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 combination meter run-frat tire warning
lamp and buzzer are activated.

Transmitter Wake Up OperationNES000GW
WITH ACTIVATION TOOL
1. With the transmitter activation tool (J-45295) pushed against the
front-left transmitter, press the button for 5 seconds.

When ignition switch ON, as the low tire pressure warning
lamp blinks per the following diagram, the respective transmit-
ter then must be woken up.
2. Register the ID of wheel that low tire pressure warning lamp flashes. When wake up of registered wheel has been completed, turn signal lamp flashes two times.
3. After completing wake up all transmitters, make sure low tire pressure warning lamp goes out.

Self-DiagnosisNES000GX
DESCRIPTION
During driving, the low tire pressure warning system receives the signal transmitted from the transmitter
installed in each wheel, and gives alarms when the tire pressure becomes low. The control unit (BCM) of this
system has pressure judgment and trouble diagnosis functions.
FUNCTION
When the low tire pressure warning 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 and the buzzer sounds.
