PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NES000LR
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.
PrecautionsNES000LS

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-17, "
Control Unit Input/Output
Signal Standard" .

Revision: 2006 December 2006 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 judgement 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 and buzzer are activated.
Low Tire pressure Warning Lamp Indication
Note 1: Standard air pressure is for 220 kpa (2.2 kg/cm2 , 32 psi) vehicles.
DISPLAY UNIT
Displays the air pressure of each tire.

After the ignition switch is turned ON, the pressure values are
not displayed until the data of each wheel stabilizes.

ID Registration ProcedureNES000GV
ID REGISTRATION WITH ACTIVATION TOOL
This procedure must be done after replacement of a transmitter or BCM.
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunction might be detected
during self-diagnosis depending on control unit which performs CAN communication.
1. With the ignition switch OFF, connect CONSULT-II and CONSULT-II CONVERTER to the data link con- nector, then turn the ignition switch ON.
2. Select “START (NISSAN BASED VHCL)”.
3. Select “BCM” on “SELECT SYSTEM” screen. NOTE:
If “BCM” is not indicated, go to GI-39, "
CONSULT-II Data Link Connector (DLC) Circuit" .
4. Select “AIR PRESSURE MONITOR” on “SELECT WORK ITEM” screen.
5. Select “WORK SUPPORT” on “SELECT DIAG MODE” screen, and select “ID REGIST”.
6. With the activation tool (J-45295) pushed against the front-left transmitter position of the tire air valve, press and hold the but-
ton 5 seconds.
7. Register the IDs in order from FR LH, FR RH, RR RH or RR LH. When ID registration of each wheel has been completed, a buzzer sounds and turn signal lamp (LH/ RH) blinks.
8. After completing all ID registrations, press “END” to complete the procedure.
NOTE:
Be sure to register the IDs in order from FR LH, FR RH, RR RH, to RR LH, or the self-diagnostic results dis-
play will not function properly.

Transmitter Wake Up OperationNES000GW
WITH ACTIVATION TOOL
1. With the 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 warning lamp flashes. When wake up of registered wheel has been com- pleted, 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 judgement 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.
