1996 NISSAN PATHFINDER check engine light

The anti-lock brake system controls the brakes
at each wheel so the wheels will 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 maintain steering con-
trol and helps to minimize swerving and spin-
ning on slippery surfaces.
Using the system
Depress the brake pedal and hold it down.It is
not necessary to pump the brake pedal.
Doing so may result in increased stopping
distances.
Normal operation
The anti-lock brake system will not operate at
speeds below 3 to 6 MPH (5 to 10 km/h) to
completely stop the vehicle. (The speeds will
vary according to road conditions.) When the
anti-lock system senses that one or more
wheels are close to locking up, the actuator
(under the hood) rapidly applies and releases
hydraulic pressure (like pumping the brakes
very quickly). While the actuator is working,
you may feel a pulsation in the brake pedal
and hear a noise or vibration from the actuator
under the hood. This is normal and indicates
that the anti-lock system is working properly.However, the pulsation may indicate that road
conditions are hazardous and extra care is
required while driving.
If a tire slips on rough roads for more than
10 seconds, the ABS brake warning light
may come on. Turn OFF the ignition key,
restart the engine and drive the vehicle at
speeds above 20 MPH (30 km/h). If the
warning light does not go out, have the
vehicle checked at a NISSAN dealer.
Self-test feature
The anti-lock brake system consists of elec-
tronic sensors, electric pumps, and hydraulic
solenoids controlled by a computer. The com-
puter 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 ªself-testº occurs, you may
hear a ªclunkº noise and/or feel a ªpulsationº 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 ªABSº
brake warning light in the dashboard. The
brake system will then behave normally, but
without anti-lock assistance.
If the light comes on during the self check, or
while you are driving, you should take your
vehicle to your NISSAN dealer for repair atyour earliest convenience.
The 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 sys-
tem. Stopping distances may also be
longer on rough, gravel or snow covered
roads, or if you are using tire chains.
Always maintain a safe distance from
the vehicle in front of you. Ultimately,
the responsibility for safety of self and
others rests in the hands of the driver.
Tire type and condition may also affect
braking effectiveness.
IWhen replacing tires, install the
specified size of tires on all 4 wheels.
Refer to ªWheels and tiresº in the
ªDo-it-yourself operationsº section.

CHANGING OIL FILTER
1. Park the vehicle on a level surface and
apply the parking brake.
2. Turn the engine off.
3. Loosen the oil filter with an oil filter wrench.
(A specialcap-typewrench will assist with
oil filter removal on models with the V6
engine. This tool can be purchased from
your NISSAN dealer.) Then remove the oil
filter by turning it by hand.
Be careful not to burn yourself, as the
engine oil may be hot.
4. Wipe the engine oil filter mounting surface
with a clean rag.
Be sure to remove any old rubber gasket
remaining on the mounting surface of the
engine.
5. Coat the rubber gasket on the new filter
with engine oil.
6. Screw in the oil filter until a slight resistance
is felt, then tighten an additional 2/3 turn.
7. Start the engine and check for leakage
around the oil filter. Correct as required.
8. Turn the engine off and wait several min-
utes. Check the oil level. Add engine oil if
necessary.
IWhen engine is running, keep hands
and clothing away from any moving
parts such as fan and drive belt.

Add fluid when the low washer fluid warning
light comes on. Add a washer solvent to the
water for better cleaning. In the winter season,
add a windshield washer anti-freeze. Follow
the manufacturer's instructions for the mixture
ratio.
Type B
To check the fluid level, use your finger to plug
the center hole of the cap/tube assembly (as
shown above), then remove it from the tank. If
there is no fluid in the tube, add fluid.Add a washer solvent to the water for better
cleaning. In the winter season, add a wind-
shield washer anti-freeze. Follow the manufac-
turer's instructions for the mixture ratio.
Do not substitute engine anti-freeze
coolant for window washer solution.

If it is out of the range shown above, see your
NISSAN dealer.
See your NISSAN dealer and have it
checked if the brake pedal height does
not return to normal.
Brake pad wear indicators
The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, it will make a high
pitched scraping or screeching sound when
the vehicle is in motion whether or not the
brake pedal is depressed. Have the brakes
checked as soon as possible if the wear indi-
cator sound is heard.
Under some driving or climate conditions, oc-
casional brake squeak, squeal or other noise
may be heard. Occasional brake noise during
light to moderate stops is normal and does not
affect the function or performance of the brake
system.
The rear drum brakes (if so equipped) do not
have audible wear indicators. Should you ever
hear an unusually loud noise from the rear
drum brakes, have them inspected as soon as
possible by your NISSAN dealer.
Proper brake inspection intervals shouldbe followed.For more information regarding
brake inspections, see the appropriate main-
tenance schedule information in the ªMainte-
nance Scheduleº section of this manual.

Check the brake booster function with the
following steps:
1. With the engine off, press and release the
brake pedal several times. When brake
pedal movement (distance of travel) re-
mains the same from one pedal application
to the next, continue on to the next step.
2. While depressing the brake pedal, start the
engine. The pedal height should drop a
little.
3. With the brake pedal depressed, stop the
engine. Keeping the pedal depressed for
about 30 seconds, the pedal height should
not change.
4. Run the engine for one minute without
depressing the brake pedal, then turn it off.
Depress the brake pedal several times. The
pedal travel distance will decrease gradu-
ally with each depression as the vacuum is
released from the booster.
If the brakes do not operate properly, have the
brake checked by your NISSAN dealer.Press the pedal by hand and be sure the free
travel is within the above limit. If free travel is
out of the range shown above, see your NIS-
SAN dealer.

Using unleaded gasoline with an octane
rating lower than stated above can cause
persistent, heavy ªspark knockº. (ªSpark
knockº is a metallic rapping noise.) If se-
vere, this can lead to engine damage. If you
detect a persistent heavy spark knock even
when using gasoline of the stated octane
rating, or if you hear steady spark knock
while holding a steady speed on level
roads, have your dealer correct the condi-
tion. Failure to correct the condition is
misuse of the vehicle, for which NISSAN is
not responsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may
cause excessive fuel consumption or damage
to the engine. If any of the above symptoms
are encountered, have your vehicle checked at
a NISSAN dealer or other competent service
facility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is no
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time.
