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

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.
