PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NES000LO
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 for Battery ServiceNES000LP
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.
Service Notice or PrecautionsNES000LQ

Low tire pressure warning lamp flashes 1min., then turns ON when occurring any malfunction except low
tire pressure.
Delete the memory with CONSULT-III, or register the ID to turn low tire pressure warning lamp OFF. Refer
to WT-21, "
ID Registration Procedure" .

ID registration is required when replacing or rotating wheels. replacing transmitter or BCM. Refer to WT-
21, "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 November2007 350Z
TIRE PRESSURE MONITORING SYSTEMPFP:40300
System ComponentsNES0001A
System DescriptionNES0001B
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 receives the air pressure signal
transmitted by the transmitter in each wheel.

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
operations. It also has a judgement function to detect a system mal-
function.
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 are activated.
Low tire pressure warning lamp indication
NOTE:
Standard air pressure is for 240 kpa (2.4 kg/cm2 , 35 psi) vehicles.

Can CommunicationNES000A0
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-49, "
CAN
Communication Signal Chart" .
