Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AFS00289
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 Brake SystemAFS001S3

Recommended fluid is brake fluid “DOT 3”.

Do not reuse drained brake fluid.

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.

Do not use mineral oils such as gasoline or kerosene to clean. They will ruin rubber parts and cause
improper operation.

Using a flare nut crowfoot and torque wrench, securely tighten
brake tube flare nuts.

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.

Before working, turn ignition switch OFF and disconnect electri-
cal connectors of ABS actuator and electric unit (control unit) or
battery negative terminal.

When installing brake piping, be sure to check torque.
Precautions for Brake ControlAFS001S4

During VDC/TCS/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 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, VDC/TCS/ABS
function may have a malfunction or error.

For Fast and Accurate DiagnosisAFS001SR
PRECAUTIONS FOR DIAGNOSIS

Before performing diagnosis, always read precautions. Refer to BRC-12, "How to Proceed With Diagno-
sis" .

If ABS actuator and electric unit (control unit), steering angle sensor, steering system parts or suspension
system parts have been replaced, or if alignment has been adjusted, be sure to adjust neutral position of
steering angle sensor before driving. Refer to BRC-6, "
Adjustment of Steering Angle Sensor Neutral Posi-
tion" .

After diagnosis is finished, be sure to erase memory. Refer to BRC-27, "SELF-DIAGNOSIS" .

When checking continuity and voltage between units, be sure to check for disconnection, looseness,
bend, or collapse of connector terminals. If any malfunction is found, repair or replace connector termi-
nals.

For intermittent symptoms, possible cause is malfunction in harness, harness connector, or terminals.
Move harness, harness connector, and terminals to check for poor connections.

If a circuit tester is used for the check, be careful not to forcibly extend any connector terminal.

To use CONSULT-II to perform self-diagnosis of ABS actuator and electric unit (control unit), active tests,
or work support, first stop work, then connect CONSULT-II and select “ABS”.

While self-diagnostic results of CONSULT-II shows malfunction, if CONSULT-II active test is performed,
an engine system error may be indicated. In this case, start engine to resume the normal screen.

VDC/TCS/ABS system electronically controls brake operation and engine output. The following symptoms
may be caused by normal operations:
Symptom Symptom description Result
Motor operation noiseThis is noise of motor inside ABS actuator and electric unit (control unit).
Slight noise may occur during VDC, TCS, and ABS operation.
Normal
When the vehicle speed goes over 20 km/h (12.5 MPH), motor and
valves operating noise may be heard. It happens only once after IGN
(ignition) is ON. This is a normal status of the system operation check.
System operation check
noiseWhen engine starts, slight “click” noise may be heard from engine room.
This is normal and is part of system operation check.Normal
VDC/TCS operation
(SLIP indicator lamp blink-
ing)TCS may activate momentarily if wheel speed changes when driving
over location where friction coefficient varies, when up/downshifting, or
when fully depressing accelerator pedal.
Normal
Cancel the VDC/TCS
function for the
inspection on a chas-
sis dynamometer. For inspection of speedometer or other instruments, press
VDC OFF SW to turn VDC/TCS function off.
When accelerator pedal is depressed on a chassis dynamometer (fixed
front-wheel type), vehicle speed will not increase. This is not normal. It is
result of TCS being activated by stationary front wheels. Warning lamp
may also illuminate to indicate “sensor system error”. This is also nor-
mal, and is the result of the stationary front wheels being detected. To be
certain, restart engine, and drive vehicle at 30 km/h (19 MPH) or more.
Make sure warning lamp does not illuminate.
ABS operation (Longer stop-
ping distance)On roads with low friction coefficients, such as snowy roads or gravel
roads, vehicles with ABS may require a longer stopping distance. There-
fore, when driving on such roads, avoid overconfidence and keep speed
sufficiently low.Normal
Insufficient feeling of accel-
erationDepending on road conditions, driver may feel that feeling of accelera-
tion is insufficient. This is because traction control, which controls
engine and brakes to achieve optimal traction, has the highest priority
(for safety). As a result, there may be times when acceleration is slightly
less than usual for the same accelerator pedal operation.Normal
