Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BFS000CK
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 SystemBFS000CL

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 ControlBFS000CM

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 condition 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.

FunctionsBFS000CP
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.

BRC-6
[ABS]
SYSTEM DESCRIPTION

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 FunctionBFS000CR
ABS, EBD SYSTEM
In case of electrical malfunctions with ABS, ABS warning lamp will turn on. In case of electrical malfunctions
with EBD, brake warning lamp and ABS warning lamp will turn on. Simultaneously, ABS become one of follow-
ing conditions of the fail-safe function.

For ABS malfunction, only EBD is activated and condition of vehicle is same condition of vehicles without
ABS system.
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.

For EBD malfunction, EBD and ABS become inoperative, and condition of vehicle is same as condition of
vehicles without ABS, EBD system.

PRECAUTIONS FOR DIAGNOSIS

Be sure to check the procedures of “How to Perform Trouble Diagnosis” in advance. Refer to GI-4, "Gen-
eral Precautions" .

Always erase memory after completing trouble diagnosis. Refer to BRC-17, "ERASE MEMORY" .

When checking continuity and voltage between units, be sure to check for disconnection, looseness,
bend, or collapse for connector terminals. Repair or replace applicable part if any non-standard condition
is detected.

Intermittent malfunctions may be caused by a poor connection in the harness, connectors, and terminals.
Move harnesses, harness connectors, and terminals by hand to make sure all connections are solid and
undamaged.

Do not to forcibly extend any connector terminal if a circuit tester is used for the check.

The symptom shown in the table below may occur, but the system is operating normally.
Basic InspectionBFS000D4
BRAKE FLUID LEVEL, LEAKAGE AND BRAKE PAD
1. Check fluid level in the brake fluid reservoir tank. Refill the brake fluid if fluid level is low.
2. Check the area around the brake piping and ABS actuator and electric unit (control unit) for leakage. If
leakage or oozing is detected, check as follows:

If ABS actuator and electric unit (control unit) connections are loose, tighten the flare nut of the piping to
the specified torque. Check again for leakage, and make sure that there is no fluid leakage.

If the flare nuts at the connections and the threads of the actuator are damaged, replace the damaged
parts. Then check again for leakage, and make sure that there is no fluid leakage.

If leakage or oozing is detected on the parts other than actuator connections, wipe with a clean cloth
and check again. If there is still leakage or oozing, replace the damaged part.

If leakage or oozing is detected on actuator body, wipe with a clean cloth and check again. If there is
still leakage or oozing, replace ABS actuator and electric unit (control unit).
CAUTION:
ABS actuator and electric unit (control unit) cannot be disassembled.

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.

PRECAUTIONS FOR DIAGNOSIS

Be sure to check the procedures of “How to Perform Trouble Diagnosis” in advance. Refer to GI-4, "Gen-
eral Precautions" .

Always adjust the neutral position of steering angle sensor before driving when removing and installing
ABS actuator and electric unit (control unit), steering angle sensor, suspension parts and adjusting align-
ment. Refer to BRC-40, "
Adjustment of Steering Angle Sensor Neutral Position" .

Always erase memory after completing trouble diagnosis. Refer to BRC-58, "ERASE MEMORY" .

When inspection of the continuity or voltage between modules or units is performed, check connector ter-
minals for disconnection, looseness, bend, or collapse. Repair or replace applicable part if any non-stan-
dard condition is detected.

Intermittent malfunctions may be caused by a poor connection in the harness, connectors, and terminals.
Move harnesses, harness connectors, and terminals by hand to make sure all connections are solid and
undamaged.

Do not to forcibly extend any connector terminal if a circuit tester is used for the check.

The symptom shown in the table may occur, but the system is operating normally.
Symptom Symptom description Result
Motor operation soundThis is the operation sound of the motor in the actuator and electric unit.Slight
sound may occur during VDC, TCS and ABS operation.
Normal
Just after the engine starts, the motor operating noise may be heard. This is a
normal status of the system operation check.
System operation check soundWhen engine starts, “click” sound may be heard from engine room. This is nor-
mal status of system operation check.Normal
VDC/TCS operation
(SLIP indicator lamp ON)TCS may activate momentarily if wheel speed changes when driving over
location where friction coefficient varies, when downshifting, or when fully
depressing accelerator pedal.
Normal
Cancel the VDC/
TCS function for
the inspection on
a chassis dyna-
mometer. Before the speed meter inspection, push VDC OFF switch to cancel the VDC/
TCS function.
When accelerator pedal is depressed on a chassis dynamometer (front wheel
fixing type), the vehicle speed will not increase. This is normal. It is result of
TCS being activated by stationary front wheels. The warning lamp may also
turn on to show “sensor system malfunction” in this case. This is also normal,
and is the result of the stationary front wheels being detected. Restart engine,
and drive the vehicle at 30 km/h (19 MPH) or more to make sure that the warn-
ing lamp no longer turns on.
ABS operation
(Longer stopping distance)When driving on roads with a low coefficient of friction, such as snowy roads or
gravel roads, the stopping distance is sometimes longer for vehicles equipped
with ABS. Therefore, when driving on such roads, drive at a sufficiently
reduced speed to be safe.Normal
Sluggish feelDepending on road conditions, the driver may have a sluggish feel. This is
because traction control, which controls engine and brakes to achieve optimal
traction, has the highest priority (for safety). As a result sometimes the driver
has a less slight sluggish feel in response than usual acceleration feel.Normal
