Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BFS000G3
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. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
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 Brake SystemBFS000DL
Recommended fluid is brake fluid “DOT 3” or “DOT 4”. Refer to MA-14, "RECOMMENDED FLUIDS AND
LUBRICANTS" .
Never reuse drained brake fluid.
Be careful not to splash brake fluid on painted areas.
To clean or wash all parts of master cylinder and disc brake caliper, use clean brake fluid.
Never use mineral oils such as gasoline or kerosene. They will
ruin rubber parts of the hydraulic system.
Using a flare nut wrench when removing flare nuts, and use a
flare nut torque wrench when tighten brake tube flare nuts.
When installing brake tubes, be sure to check torque.
Before working, turn ignition switch OFF and disconnect electri-
cal connector of ABS actuator and electric unit (control unit) or
battery negative terminal.
WARNING:
Clean brake pads and shoes with a waste cloth, then wipe with
a dust collector.
Precautions for Brake ControlBFS000DM
During ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.
Just after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating noise may
be heard from engine room. This is a normal status of operation check.
Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
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
diagnostic servicing. Besides electrical system inspection, check brake booster operation, brake fluid
level, and fluid leaks.
If tire size and type are used in an improper combination, or brake pads are not Genuine NISSAN parts,
stopping distance or steering stability may deteriorate.
If there is a radio, antenna, or antenna lead-in wire (including wiring) near control module, ABS function
may have a malfunction or error.
If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness
pinches, open circuits, and improper wiring.
If the following components are replaced with non-genuine components or converted, the VDC OFF indi-
cator lamp and SLIP indicator lamp may turn on or the VDC system may not operate properly. Compo-
nents related to suspension (Shock Absorber, Strut, Spring, Bush, etc.), Tires, wheels (exclude specified

Driving in the condition of breakage or excessive wear of the suspension, tires or components related to
the brakes may cause the VDC OFF indicator lamp and the SLIP indicator lamp to turn on, and the VDC
system may not operate properly.
When the TCS or VDC is activated by sudden acceleration or sudden turn, some noise may occur. The
noise is a result of the normal operation of the TCS and VDC.
When driving on roads which have extreme slopes (such as mountainous roads) or high banks (such as
sharp carves on a freeway), the VDC may not operate normally, or the VDC OFF indicator lamp and the
SLIP indicator lamp may turn on. However, this is not a incident if normal operation can be resumed after
restarting the engine.
Sudden turns (such as spin turns, acceleration turns), drifting, etc; when VDC function is OFF (VDC OFF
switch ON), may cause that the yaw rate/side/decel G sensor system indicate a incident. However this is
not a incident if normal operation can be resumed after restarting the engine.

VDC
In addition to the TCS/ABS function, the steering amount and brake operation amount are detected from
the steering angle sensor and brake switch, and the driving condition (amount of under-steering/over-
steering) is determined from information from the yaw rate/side/decel G sensor, vehicle speed sensor, etc.
This information is used to improve vehicle stability by controlling the braking and engine power to all four
wheels.
The SLIP indicator lamp flashes to inform the driver of VDC operation.
During VDC operation, the body and brake pedal lightly vibrate and mechanical noises may be heard.
This is normal.
ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp might turn on when the vehicle is
subject to strong shaking or large vibration, such as when the vehicle is on a turn table or a ship while
engine is running. In this case, restart engine on a normal road, and if ABS warning lamp, VDC OFF indi-
cator lamp, and SLIP indicator lamp turn off, there is no malfunction.
TCS
Speed signals for 4 wheels control engine output and transaxle conditions so that slip rate of the drive
wheels is optimum. ABS actuator and electric unit (control unit) detects wheelspin. Output from the control
unit controls brake fluid pressure to both LH and RH drive wheels while cutting fuel to the engine and clos-
ing the throttle valve to reduce engine torque when wheelspin is detected. Throttle position is continuously
controlled to ensure the appropriate engine torque at all times.
Depending on road conditions, the driver may have a sluggish feel. This is normal, because the optimum
traction has the highest priority by TCS operation.
TCS may be activated momentarily the vehicle suddenly accelerates, suddenly downshifts, or is driven on
a road with a varying surface friction coefficient.
During TCS operation, it informs a driver of system operation by flashing SLIP indicator lamp.

[VDC/TCS/ABS]
SYSTEM DESCRIPTION
ABS
The Anti-Lock Brake System is a function that detects wheel revolution while braking, and it improves
handling stability during sudden braking by electrically preventing 4 wheel lock. Maneuverability is also
improved for avoiding obstacles.
If the electrical system breaks down, then the fail-safe function is activated, ABS becomes inoperative,
and ABS warning lamp turns on.
Electrical system diagnosis by CONSULT-II is available.
During ABS operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.
Just after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating noise may
be heard from engine room. This is a normal status of operation check.
Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
EBD
Electronic Brake Distribution is a function that detects subtle slippages between front and rear wheels dur-
ing braking, and it improves handling stability by electronically controlling Brake Fluid Pressure which
results in reduced rear wheel slippage.
In case of electrical system break down, the fail-safe function is activated, EBD and ABS becomes inoper-
ative, and ABS warning lamp and brake warning lamp are turned on.
Electrical system diagnosis by CONSULT-II is available.
During EBD operation, brake pedal lightly vibrates and a mechanical noise may be heard. This is normal.
Just after starting vehicle after ignition switch ON, brake pedal may vibrate or motor operating sound may
be heard from engine compartment. This is a normal condition of operation check.
Stopping distance may be longer than that of vehicles without EBD when vehicle drives on rough, gravel,
or snow-covered (fresh, deep snow) roads.
Fail-Safe FunctionBFS000DU
VDC/TCS SYSTEM
In the event an electrical malfunction occurs in the system, the VDC OFF indicator lamp and SLIP indicator
lamp in the combination meter will light up. At the same time, the VDC/TCS control is not performed, and the
vehicle is in the same conditions as a vehicle not equipped with the VDC/TCS function. However, the ABS
control operates normally.
If a malfunction is detected in the throttle control system, the VDC/TCS control is not performed and only the
ABS control operates normally.
CAUTION:
If fail-safe mode is initiated, perform self-diagnosis for the VDC/TCS/ABS control system.
ABS, EBD SYSTEM
In the event there is a malfunction with the electrical system, the ABS warning lamp, VDC OFF indicator lamp,
and SLIP indicator lamp will turn on when it is the ABS that is malfunctioning, and the brake warning lamp,
ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp will turn on when it is the EBD that is
malfunctioning. At the same time, the VDC/TCS/ABS will become one of the following conditions by the fail-
safe function.
When the ABS malfunctions, only the EBD operates. The condition is the same as that of models with
VDC/TCS/ABS.
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.
When the EBD malfunctions, the EBD and ABS will not operate. The condition is the same as that of mod-
els without VDC/TCS/ABS and EBD.

CAN CommunicationBFS000G2
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 on 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, "

How to Perform Trouble Diagnosis Quick and Accurate RepairBFS000DX
INTRODUCTION
Most important point to perform diagnosis is to understand systems (control and mechanism) in vehicle
thoroughly.
It is also important to clarify customer complaints before inspec-
tion.
First of all, reproduce symptoms, and understand them fully.
Ask the customer about his/her complaints carefully. In some
cases, it will be necessary to check symptoms by driving vehicle
with the customer.
NOTE:
Customers are not professionals. Do not assume “maybe cus-
tomer means...” or “maybe the customer mentioned this symp-
tom”.
It is essential to check symptoms right from beginning in order to
repair a malfunction completely.
For an intermittent malfunction, it is important to reproduce
symptoms based on an interview with customers and past
examples. Do not perform an 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 connec-
tors by hand. When repairs are performed without any symptom
check, no one can judge if malfunction has actually been elimi-
nated.
After diagnosis, make sure to perform “erase memory”. Refer to
BRC-58, "
ERASE MEMORY" .
For an intermittent malfunction, move harness or harness connector by hand to check poor contact or
false open circuit.
Always read “GI section” to confirm general precautions. Refer to GI-4, "General Precautions" .
