ECU NISSAN MAXIMA 2016 A36 / 8.G Workshop Manual

Your NISSAN has been designed to have mini-
mum maintenance requirements with long ser-
vice intervals to save you both time and money.
However, some day-to-day and regular mainte-
nance is essential to maintain your NISSAN’s
good mechanical condition, as well as its emis-
sions and engine performance.
It is the owner’s responsibility to make sure that
the scheduled maintenance, as well as general
maintenance, is performed.
As the vehicle owner, you are the only one who
can ensure that your vehicle receives proper
maintenance. You are a vital link in the mainte-
nance chain.
Scheduled maintenance
For your convenience, both required and optional
scheduled maintenance items are described and
listed in your “NISSAN Service and Maintenance
Guide”. You must refer to that guide to ensure
that necessary maintenance is performed on your
NISSAN at regular intervals.
General maintenance
General maintenance includes those items which
should be checked during normal day-to-day op-
eration. They are essential for proper vehicle op-
eration. It is your responsibility to perform these
maintenance procedures regularly as prescribed.Performing general maintenance checks requires
minimal mechanical skill and only a few general
automotive tools.
These checks or inspections can be done by you,
a qualified technician, or, if you prefer, a NISSAN
dealer.
Where to go for service
If maintenance service is required or your vehicle
appears to malfunction, have the systems
checked and corrected by a NISSAN dealer.
NISSAN technicians are well-trained specialists
who are kept up-to-date with the latest service
information through technical bulletins, service
tips, and in-dealership training programs. They
are completely qualified to work on NISSAN ve-
hicles
before they work on your vehicle, rather
than after they have worked on it.
You can be confident that a NISSAN dealer’s
service department performs the best job to meet
the maintenance requirements on your vehicle —
in a reliable and economical way. During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section. If
you detect any unusual sounds, vibrations or
smells, be sure to check for the cause or have a
NISSAN dealer do it promptly. In addition, you
should notify a NISSAN dealer if you think that
repairs are required.
When performing any checks or maintenance
work, closely observe the “Maintenance precau-
tions” in this section.

When driving in areas using road salt or other
corrosive materials, check lubrication frequently.
Lights*Clean the headlights on a regular basis.
Make sure that the headlights, stop lights, tail
lights, turn signal lights, and other lights are all
operating properly and installed securely. Also
check headlight aim.
Road wheel nuts (lug nuts)* When checking
the tires, make sure no wheel nuts are missing,
and check for any loose wheel nuts. Tighten if
necessary.
Tire rotation* Tires should be rotated every
5,000 miles (8,000 km).
Tires* Check the pressure with a gauge often
and always prior to long distance trips. If neces-
sary, adjust the pressure in all tires, including the
spare, to the pressure specified. Check carefully
for damage, cuts or excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components Replace the TPMS
transmitter grommet seal, valve core and cap
when the tires are replaced due to wear or age.
Wheel alignment and balance If the vehicle
should pull to either side while driving on a
straight and level road, or if you detect uneven or
abnormal tire wear, there may be a need for wheel alignment. If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing may be
needed.
● For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the Warranty Information Booklet.
Windshield Clean the windshield on a regular
basis. Check the windshield at least every six
months for cracks or other damage. Have a dam-
aged windshield repaired by a qualified repair
facility.
Windshield wiper blades* Check for cracks or
wear if they do not wipe properly.
Inside the vehicle
The maintenance items listed here should be
checked on a regular basis, such as when per-
forming periodic maintenance, cleaning the ve-
hicle, etc.
Additional information on the following
items with an “*” is found in this section.
Accelerator pedal Check the pedal for smooth
operation and make sure the pedal does not bind
or require uneven effort. Keep the floor mat away
from the pedal.

and the engine is not running. To avoid
injury, always disconnect the negative
battery cable before working near the
fan.
● If you must run the engine in an en-
closed space such as a garage, be sure
there is proper ventilation for exhaust
gases to escape.
● Never get under the vehicle while it is
supported only by a jack. If it is neces-
sary to work under the vehicle, support
it with safety stands.
● Keep smoking materials, flame and
sparks away from the fuel tank and
battery.
● On gasoline engine models, the fuel
filter or fuel lines should be serviced by
a NISSAN dealer because the fuel lines
are under high pressure even when the
engine is off.

●Keep the battery surface clean and dry.
Clean the battery with a solution of baking
soda and water.
● Make certain the terminal connections are
clean and securely tightened.
● If the vehicle is not to be used for 30 days or
longer, disconnect the negative (-) battery
terminal cable to prevent discharge.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as: 1. Installation or extended use of electronic accessories that consume battery power
when the engine is not running (Phone char-
gers, GPS, DVD players, etc.)
2. Vehicle is not driven regularly and/or only driven short distances. In these cases, the
battery may need to be charged to maintain
battery health.WARNING
●Do not expose the battery to flames, an
electrical spark or a cigarette. Hydrogen
gas generated by the battery is explo-
sive. Explosive gases can cause blind-
ness or injury. Do not allow battery fluid
to contact your skin, eyes, fabrics or
painted surfaces. Sulfuric acid can
cause blindness or injury. After touch-
ing a battery or battery cap, do not
touch or rub your eyes. Thoroughly
wash your hands. If the acid contacts
your eyes, skin or clothing, immediately
flush with water for at least 15 minutes
and seek medical attention.
● Do not operate the vehicle if the fluid in
the battery is low. Low battery fluid can
cause a higher load on the battery
which can generate heat, reduce battery
life, and in some cases lead to an
explosion.
● When working on or near a battery, al-
ways wear suitable eye protection and
remove all jewelry.
● Battery posts, terminals and related ac-
cessories contain lead and lead com-
pounds. Wash hands after handling. ●

If the brakes do not operate properly, have the
brakes checked by a NISSAN dealer.
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front and rear disc-type brakes self-adjust
every time the brake pedal is applied.
WARNING
See a NISSAN dealer for a brake system
check 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 re-
placement, a high pitched scraping or screech-
ing sound will be heard when the vehicle is in
motion. The noise will be heard whether or not the
brake pedal is depressed. Have the brakes
checked as soon as possible if the wear indicator
sound is heard.
Under some driving or climate conditions, occa-
sional 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.Proper brake inspection intervals should
be followed.
For additional information regard-
ing brake inspections, refer to the appropriate
maintenance schedule information in the
“NISSAN Service and Maintenance Guide”.
If any electrical equipment does not operate,
check for an open fuse.
Fuses are used in the passenger and engine
compartment. Spare fuses are provided and can
be found in the passenger compartment fuse
box.

5. Determine the combined weight ofluggage and cargo being loaded on
the vehicle. That weight may not
safely exceed the available cargo and
luggage load capacity calculated in
step 4.
Before driving a loaded vehicle, confirm
that you do not exceed the Gross Vehicle
Weight Rating (GVWR) or the Gross Axle
Weight Rating (GAWR) for your vehicle.
For additional information, refer to “Mea-
surement of weights” in this section.
Also check tires for proper inflation pres-
sures. For additional information, refer to
the Tire and Loading Information label.
LOADING TIPS
● The GVW must not exceed GVWR
or GAWR as specified on the
F.M.V.S.S./C.M.V.S.S. certification
label.
● Do not load the front and rear axle to
the GAWR. Doing so will exceed the
GVWR.
WARNING
● Properly secure all cargo with
ropes or straps to help prevent it
from sliding or shifting. Do not
place cargo higher than the seat-
backs. In a sudden stop or colli-
sion, unsecured cargo could
cause personal injury.
● Do not load your vehicle any
heavier than the GVWR or the
maximum front and rear GAWRs.
If you do, parts of your vehicle can
break, tire damage could occur,
or it can change the way your
vehicle handles. This could result
in loss of control and cause per-
sonal injury.
● Overloading not only can shorten
the life of your vehicle and the
tire, but can also cause unsafe
vehicle handling and longer brak-
ing distances. This may cause a
premature tire failure which
could result in a serious accident
and personal injury. Failures
caused by overloading are not
covered by the vehicle’s warranty.MEASUREMENT OF WEIGHTS
Secure loose items to prevent weight
shifts that could affect the balance of your
vehicle. When the vehicle is loaded, drive
to a scale and weigh the front and the rear
wheels separately to determine axle
loads. Individual axle loads should not ex-
ceed either of the gross axle weight rat-
ings (GAWR) . The total of the axle loads
should not exceed the gross vehicle
weight rating (GVWR) . These ratings are
given on the vehicle certification label. If
weight ratings are exceeded, move or re-
move items to bring all weights below the
ratings.
