PRECAUTIONS
[ABS] PFP:00001
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" NFS0001M
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:
q 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.
q 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.
q 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 Service NFS0001N
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.
Precautions for Brake System NFS0001O
q Recommended fluid is brake fluid "DOT 3". Refer to MA-11, "RECOMMENDED FLUIDS AND LUBRI-
CANTS" .
q Never reuse drained brake fluid.
q Be careful not to splash brake fluid on painted areas such as body. If brake fluid is splashed, wipe it off
and flush area with water immediately.
q Never use mineral oils such as gasoline or kerosene to clean. They will ruin rubber parts and cause
improper operation.
q Use a flare nut wrench when removing flare nuts, and use a flare
nut crowfoot and torque wrench when tighten brake tube flare
nuts.
q When installing brake tubes, be sure to check torque.
q Brake system is an important safety part. If a brake fluid leak is
detected, always disassemble the affected part. If a malfunction
is detected, replace part with a new one.
q Before working, turn ignition switch OFF and disconnect electri-
cal connector of ABS actuator and electric unit (control unit) or
the battery negative terminal.
SBR686C
WARNING:
Clean brake pads and shoes with a waste cloth, then wipe with a dust collector.
Precautions for Brake Control NFS0001P
q During ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.
q Just after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating noise may
be heard from engine compartment. This is a normal status of operation check.
q Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
Revision: 2006 November BRC-4 2007 350Z
PRECAUTIONS
[ABS]
q When an error is indicated by ABS or another warning lamp, collect all necessary information from cus-
tomer (what symptoms are present under what conditions) and check for simple causes before starting A
diagnostic servicing. Besides electrical system inspection, check booster operation, brake fluid level, and
oil leaks.
q If tire size and type are used in an improper combination, or brake pads are not Genuine NISSAN parts, B
stopping distance or steering stability may deteriorate.
q If there is a radio, antenna, or antenna lead-in wire (including wiring) near control module, ABS function
may have a malfunction or error.
C
q If aftermarket parts (car stereo, CD player, etc.) Have been installed, check for incidents such as harness
pinches, open circuits, and improper wiring.

ABS Function NFS0001T
q The Anti-Lock Braking System is a function that detects wheel revolution while braking, and it improves H
handling stability during sudden braking by electrically preventing 4 wheel lock. Maneuverability is also
improved for avoiding obstacles.
q If the electrical system breaks down, then the Fail-Safe function starts, the ABS becomes inoperative, and I
the ABS warning lamp turns on.
q Electrical System Diagnosis by CONSULT-III is available.
J
EBD Function NFS0001U
q Electronic Brake Distribution is a function that detects subtle slippages between the front and rear wheels
during braking, and it improves handling stability by electronically controlling the Brake Fluid Pressure K
which results in reduced rear wheel slippage.
q In case of electrical system break down, the Fail-Safe function is activated, the EBD and ABS becomes
inoperative, and the ABS warning lamp and brake warning lamp are turned on.

q Electrical System Diagnosis by CONSULT-III is available.

CAN Communication NFS0001X
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-48, "CAN Sys-
tem Specification Chart" .

TROUBLE DIAGNOSIS

TROUBLE DIAGNOSIS PFP:00004
A
Fail-Safe Function NFS000II
ABS, EBD SYSTEM
In case of electrical problems with the ABS, the ABS warning lamp will turn on. In case of electrical problems B
with the EBD, brake warning lamp, ABS warning lamp will turn on. Simultaneously, the ABS become one of
the following conditions of the Fail-Safe function.
q For ABS trouble, only the EBD is activated and the condition of the vehicle is the same condition of vehi-
cle without ABS equipment. C
NOTE:
ABS self diagnosis sound may be heard. That is a normal condition because a self diagnosis for "Ignition
switch ON" and "The first starting" are being performed. D
q For EBD trouble, The EBD and ABS become inoperative, are the condition of the vehicle is the same as
the condition of vehicles without ABS, EBD equipment.
E
How to Proceed with Diagnosis NFS0001Y
BASIC CONCEPT
q Most important point to perform diagnosis is to understand systems (control and mechanism) in vehicle BRC
thoroughly.
q It is also important to clarify customer complaints before inspec-
tion.
First of all, reproduce symptom, and understand it fully. G
Ask customer about his/her complaints carefully. In some cases,
it will be necessary to check symptom by driving vehicle with
customer. H
NOTE:
Customers are not professionals. Do not assume "maybe cus-
tomer means..." or "maybe customer mentioned this symptom". I
EFJ0028D
q It is essential to check symptoms right from beginning in order to J
repair a malfunction completely.
For an intermittent malfunction, it is important to reproduce
symptom based on interview with customer and past examples. K
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.
L
When repairs are performed without any symptom check, no
one can judge if malfunction has actually been eliminated.
q After diagnosis, make sure to carry out "erase memory". Refer to
BRC-19, "HOW TO ERASE SELF-DIAGNOSIS RESULTS" . M
SEF233G
q For an intermittent malfunction, move harness or harness con-
nector by hand to check poor contact or false open circuit.
q Always read "GI General Information" to confirm general precautions. Refer to GI-3, "General Precau-
tions" .
