brake sensor NISSAN QUEST 2006 V42 / 3.G Owners Manual

This procedure is described in the vehicle service
manual and can be performed by a NISSAN
dealer.
ANTI-LOCK BRAKE SYSTEM (ABS)
The anti-lock brake system controls the brakes so
the wheels do not lock when braking abruptly or
when braking on slippery surfaces. The system
detects the rotation speed at each wheel and
varies the brake fluid pressure to prevent each
wheel from locking and sliding. By preventing
wheel lockup, the system helps the driver main-
tain steering control and helps to minimize swerv-
ing and spinning on slippery surfaces.
Using the system
Depress the brake pedal and hold it down.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Normal operation
The anti-lock brake system does not operate at
speeds below3-6MPH(5-10km/h) . (The
speeds vary according to road conditions.)
When driving, the anti-lock brake system con-
trols the wheels so they will not lock when brak-ing abruptly or when braking on a slippery road.
Thus, difficult steering and swerving of the ve-
hicle due to locked wheels is minimized. The
system detects the wheel rotation rate and elec-
tronically controls the pressure applied to each
brake. Slight vibration on the brake pedal accom-
panied by noise usually occurs while the ABS
system is operating. Such vibration and noise
encountered during abrupt braking is not a prob-
lem, but indicates that the system is functioning
properly. However, the pulsation may indicate
that road conditions are hazardous and extra care
is required while driving.
Self-test feature
The anti-lock brake system consists of electronic
sensors and hydraulic solenoids controlled by a
computer. The computer has a built-in diagnostic
feature that tests the system each time you start
the engine and move the vehicle at a low speed in
forward or reverse. When the self-test occurs,
you may hear a ‘‘clunk’’ noise and/or feel a pulsa-
tion in the brake pedal. This is normal and is not
an indication of any malfunction. If the computer
senses any malfunction, it switches the anti-lock
brake system off and turns on the ABS brake
warning light on the instrument panel. The brake
system then operates normally, but without anti-
lock assistance.If the light comes on during the self-test or while
driving, take the vehicle to a NISSAN dealer for
repair.
WARNING
cThe anti-lock brake system is a sophis-
ticated device, but it cannot prevent ac-
cidents resulting from careless or dan-
gerous driving techniques. It can help
maintain vehicle control during braking
on slippery surfaces, but remember that
the stopping distance on slippery sur-
faces will be longer than on normal
surfaces even with the anti-lock brake
system. Stopping distances may also
be longer on rough, gravel or snow cov-
ered roads, or if you are using tire
chains. Tire type and condition may also
affect braking effectiveness. Always
maintain a safe distance from the ve-
hicle in front of you. Ultimately, the re-
sponsibility for safety of self and others
rests in the hands of the driver.
cTire type and condition of tires may also
affect braking effectiveness.
cWhen replacing tires, install the speci-
fied size of tires on all four wheels.

cWhen installing a spare tire, make sure
it is the proper size and type as speci-
fied on the Tire and Loading Informa-
tion label. For tire placard location in-
formation, refer to “Tire and Loading
Information label” in the “Technical and
consumer information” section of this
manual.
cRefer to “Wheels and tires” in the
“Maintenance and do-it-yourself” sec-
tion of this manual.When accelerating on slippery surfaces the tire
may spin or slip. With the vehicle traction control
system (TCS) , sensors detect these movements
and control the braking and engine output to help
improve vehicle stability while accelerating.
cWhen the traction control system is operat-
ing, the slip indicator in the instrument panel
blinks.
cIf the slip indicator blinks, the vehicle is un-
der slippery conditions. Be sure to drive
carefully. See “Slip indicator light” and “Trac-
tion control system (TCS) off indicator light”
in the “Instruments and controls” section of
this manual.
cIf a malfunction occurs in the system,
the
andindicator lights
come on in the meter panel.
As long as these lights are on, the traction control
function is canceled. The vehicle will behave like
a vehicle without the system.
WARNING
cThe traction control system is designed
to help improve driving stability but
does not prevent accidents due to
abrupt steering operation at high
speeds or by careless or dangerous
driving techniques. Reduce vehicle
speed and be especially careful when
driving and cornering on slippery sur-
faces and always drive carefully.
cIf brake related parts such as brake
pads, rotors and calipers are not stan-
dard equipment or are extremely dete-
riorated, the traction control system
may not operate properly and the
indicator light may come on.
cDo not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs and bushings
are not standard equipment or are ex-
tremely deteriorated, the traction con-
trol system may not operate properly
and the
indicator light may come
on.

cWhen driving on extremely inclined sur-
faces such as higher banked corners,
the traction control system may not op-
erate properly and the
indicator
light may come on. Do not drive on
these types of roads.
cIf wheels or tires other than the recom-
mended ones are used, the traction
control system may not operate prop-
erly and the
indicator light may
come on.
cThe traction control system is not a sub-
stitute for winter tires or tire chains on a
snow covered road.When accelerating or driving on slippery sur-
faces, the tires may spin or slide. With the Vehicle
Dynamic Control (VDC) system, sensors detect
these movements and control the braking and
engine output to help improve vehicle stability.
cWhen the vehicle dynamic control (VDC)
system is operating, the slip indicator in the
instrument panel blinks.
cIf the slip indicator blinks, the road condi-
tions are slippery. Be sure to adjust your
speed and driving to these conditions. See
“Slip indicator light”, and “Vehicle dynamic
control (VDC) off indicator light” in the “In-
struments and controls” section.
cIndicator light
If malfunction occurs in the system,
the
andindicator lights come
on in the instrument panel.
As long as these indicator lights are on, the
traction control function is canceled.
If the vehicle is operated with the vehicle dynamic
control system OFF using the VDC OFF switch,
VDC functions will be turned off. The VDC sys-
tem will still try to transfer power from a slipping
drive wheel to one with more traction when the
VDC system switch is OFF. The Slip indicator will
flash if wheel spin is detected. The ABS will still
operate with the VDC system off.When the VDC system is operating, you may feel
a pulsation in the brake pedal and hear a noise or
vibration from under the hood. This is normal and
indicates that the VDC system is working prop-
erly.
The computer has a built in diagnostic feature
that tests the system each time you start the
engine and move the vehicle forward or in reverse
at a slow speed. When the self-test occurs, you
may hear a clunk noise and/or feel a pulsation in
the brake pedal. This is normal and is not an
indication of a malfunction.
WARNING
cThe vehicle dynamic control system is
designed to help improve driving stabil-
ity but does not prevent accidents due
to abrupt steering operation at high
speeds or by careless or dangerous
driving techniques. Reduce vehicle
speed and be especially careful when
driving and cornering on slippery sur-
faces and always drive carefully.
