ECU NISSAN FRONTIER 2017 D23 / 3.G Repair Manual

●The system cannot completely elimi-
nate blind spots and may not show ev-
ery object.
● Underneath the bumper and the corner
areas of the bumper cannot be viewed
on the RearView Monitor because of its
monitoring range limitation. The system
will not show small objects below the
bumper, and may not show objects
close to the bumper or on the ground.
● Objects viewed in the RearView Moni-
tor differ from actual distance because
a wide-angle lens is used.
● Objects in the RearView Monitor will
appear visually opposite compared to
when viewed in the rearview and out-
side mirrors.
● Use the displayed lines as a reference.
The lines are highly affected by the
number of occupants, fuel level, vehicle
position, road conditions and road
grade.
● Make sure that the tailgate is securely
closed when backing up.
● Do not put anything on the rearview
camera. The rearview camera is in-
stalled on the tailgate. ●
When washing the vehicle with high
pressure water, be sure not to spray it
around the camera. Otherwise, water
may enter the camera unit causing wa-
ter condensation on the lens, a mal-
function, fire or an electric shock.
● Do not strike the camera. It is a preci-
sion instrument. Otherwise, it may mal-
function or cause damage resulting in a
fire or an electric shock.
The following are operating limitations and do not
represent a system malfunction: ● When the temperature is extremely high or
low, the screen may not clearly display ob-
jects.
● When strong light directly shines on the
camera, objects may not be displayed
clearly.
● Vertical lines may be seen in objects on the
screen. This is due to strong reflected light
from the bumper.
● The screen may flicker under fluorescent
light.
● The colors of objects on the RearView Moni-
tor may differ somewhat from the actual
color of objects. ●
Objects on the monitor may not be clear in a
dark environment.
● There may be a delay when switching be-
tween views.
● If dirt, rain or snow accumulate on the cam-
era, RearView Monitor may not display ob-
jects clearly. Clean the camera.
● Do not use wax on the camera lens. Wipe off
any wax with a clean cloth dampened with a
diluted mild cleaning agent, then wipe with a
dry cloth.

WARNING
●Do not leave children or adults who
would normally require the assistance
of others alone in your vehicle. Pets
should also not be left alone. They
could accidentally injure themselves or
others through inadvertent operation of
the vehicle. Also, on hot, sunny days,
temperatures in a closed vehicle could
quickly become high enough to cause
severe or possibly fatal injuries to
people or animals.
● Properly secure all cargo with ropes or
straps to help prevent it from sliding or
shifting. Do not place cargo higher than
the seatbacks. In a sudden stop or col-
lision, unsecured cargo could cause
personal injury.
EXHAUST GAS (carbon monoxide)
WARNING
●Do not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is danger-
ous. It can cause unconsciousness or
death. ●
If you suspect that exhaust fumes are
entering the vehicle, drive with all win-
dows fully open, and have the vehicle
inspected immediately.
● Do not run the engine in closed spaces
such as a garage.
● Do not park the vehicle with the engine
running for any extended length of time.
● Keep the rear vent windows, liftgates,
doors and trunk lids (if so equipped)
closed while driving, otherwise exhaust
gases could be drawn into the passen-
ger compartment. If you must drive with
one of these open, follow these
precautions:
1. Open all the windows.
2. Set the
air recirculation but-
ton to off and the fan control dial to
high to circulate the air.
● If electrical wiring or other cable con-
nections must pass to a trailer through
the seal on the liftgate or the body,
follow the manufacturer’s recommen-
dation to prevent carbon monoxide en-
try into the vehicle. ●
The exhaust system and body should be
inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes are entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involving damage to the exhaust system, un-
derbody, or rear of the vehicle.
● If a special body, camper, or other
equipment is added for recreational or
other usage, follow the manufacturer’s
recommendation to prevent carbon
monoxide entry into the vehicle. Do not
occupy these areas while the engine is
running even if the vehicle is parked.
Some recreational vehicle appliances
such as stoves, refrigerators, heaters,
etc. may also generate carbon
monoxide.
PRECAUTIONS WHEN STARTING
AND DRIVING
5-2Starting and driving

NISSAN is committed to safe driving. However,
you must choose not to drive under the influence
of alcohol. Every year thousands of people are
injured or killed in alcohol-related collisions. Al-
though the local laws vary on what is considered
to be legally intoxicated, the fact is that alcohol
affects all people differently and most people
underestimate the effects of alcohol.
Remember, drinking and driving don’t mix! That is
true for drugs (over-the-counter, prescription)
and illegal drugs, too. Don’t drive if your ability to
operate your vehicle is impaired by alcohol,
drugs, or some other physical condition.
DRIVING SAFETY PRECAUTIONS
Your NISSAN is designed for both normal and
off-road use. However, avoid driving in deep wa-
ter or mud as your NISSAN is mainly designed for
leisure use, unlike a conventional off-road ve-
hicle.
Remember that 2-wheel drive models are less
capable than 4-wheel drive models for rough
road driving and extrication when stuck in deep
snow or mud, or the like.Please observe the following precautions:
WARNING
●
Drive carefully when off the road and
avoid dangerous areas. Every person
who drives or rides in this vehicle
should be seated with their seat belt
fastened. This will keep you and your
passengers in position when driving
over rough terrain.
● Do not drive across steep slopes. In-
stead drive either straight up or straight
down the slopes. Off-road vehicles can
tip over sideways much more easily
than they can forward or backward.
● Many hills are too steep for any vehicle.
If you drive up them, you may stall. If
you drive down them, you may not be
able to control your speed. If you drive
across them, you may roll over.
● Do not shift gears while driving on
downhill grades as this could cause
loss of control of the vehicle.
● Stay alert when driving to the top of a
hill. At the top there could be a drop-off
or other hazard that could cause an
accident. ●
If your engine stalls or you cannot make
it to the top of a steep hill, never at-
tempt to turn around. Your vehicle could
tip or roll over. Always back straight
down in R (Reverse) gear. Never back
down in N (Neutral) or with the clutch
depressed (manual transmission ve-
hicles) , using only the brake, as this
could cause loss of control.
● Heavy braking going down a hill could
cause your brakes to overheat and fade,
resulting in loss of control and an acci-
dent. Apply brakes lightly and use a low
gear to control your speed. Use the hill
descent control feature (if so
equipped) .
● Unsecured cargo can be thrown around
when driving over rough terrain. Prop-
erly secure all cargo so it will not be
thrown forward and cause injury to you
or your passengers.
5-8Starting and driving

●To avoid raising the center of gravity
excessively, do not exceed the rated
capacity of the roof rack (if so equipped)
and evenly distribute the load. Secure
heavy loads in the cargo area as far
forward and as low as possible. Do not
equip the vehicle with tires larger than
specified in this manual. This could
cause your vehicle to roll over.
● Do not grip the inside or spokes of the
steering wheel when driving off-road.
The steering wheel could move sud-
denly and injure your hands. Instead
drive with your fingers and thumbs on
the outside of the rim.
● Before operating the vehicle, ensure
that the driver and all passengers have
their seat belts fastened.
● Always drive with the floor mats in place
as the floor may become hot.
● Lower your speed when encountering
strong crosswinds. With a higher center
of gravity, your NISSAN is more affected
by strong side winds. Slower speeds
ensure better vehicle control.
● Do not drive beyond the performance
capability of the tires, even with 4WD
engaged (if so equipped) . ●
For 4WD equipped vehicles, do not at-
tempt to raise two wheels off the
ground and shift the transmission to
any drive or reverse position with the
engine running. Doing so may result in
drivetrain damage or unexpected ve-
hicle movement which could result in
serious vehicle damage or personal
injury.
● Do not attempt to test a 4WD equipped
vehicle on a 2-wheel dynamometer
(such as the dynamometers used by
some states for emissions testing) , or
similar equipment even if the other two
wheels are raised off the ground. Make
sure you inform test facility personnel
that your vehicle is equipped with 4WD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or per-
sonal injury.
● Accelerating quickly, sharp steering
maneuvers or sudden braking may
cause loss of control. ●
If at all possible, avoid sharp turning
maneuvers, particularly at high speeds.
Your NISSAN four-wheel drive vehicle
has a higher center of gravity than a
passenger car. The vehicle is not de-
signed for cornering at the same speeds
as passenger cars. Failure to operate
this vehicle correctly could result in loss
of control and/or a rollover accident.
● Always use tires of the same type, size,
brand, construction (bias, bias-belted,
or radial) , and tread pattern on all four
wheels. Install tire chains on the rear
wheels when driving on slippery roads
and drive carefully.
● Be sure to check the brakes immedi-
ately after driving in mud or water. For
additional information, refer to “Wet
brakes” in this section.
● Avoid parking your vehicle on steep
hills. If you get out of the vehicle and it
rolls forward, backward or sideways,
you could be injured.
Starting and driving5-9

●If the low tire pressure warning light
illuminates while driving, avoid sudden
steering maneuvers or abrupt braking,
reduce vehicle speed, pull off the road
to a safe location and stop the vehicle
as soon as possible. Driving with under-
inflated tires may permanently damage
the tires and increase the likelihood of
tire failure. Serious vehicle damage
could occur and may lead to an accident
and could result in serious personal in-
jury. Check the tire pressure for all four
tires. Adjust the tire pressure to the
recommended COLD tire pressure
shown on the Tire and Loading Informa-
tion label to turn the low tire pressure
warning light OFF. If you have a flat tire,
replace it with a spare tire as soon as
possible.
● Since the spare tire is not equipped with
the TPMS, when a spare tire is mounted
or a wheel is replaced, the TPMS will
not function and the low tire pressure
warning light will flash for approxi-
mately 1 minute. The light will remain
on after 1 minute. Have your tires re-
placed and/or TPMS system reset as
soon as possible. It is recommended
that you visit a NISSAN dealer for these
services. ●
Replacing tires with those not originally
specified by NISSAN could affect the
proper operation of the TPMS.
● Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pressure
sensors.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions be-
low:
Stopping the vehicle
1. Safely move the vehicle off the road and
away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Shift the manual transmission into R
(Reverse) , or the automatic transmission
into P (Park) .
4. Turn off the engine.
5. Raise the hood to warn other traffic and to signal professional road assistance person-
nel that you need assistance.
6. Have all passengers get out of the vehicle and stand in a safe place, away from traffic
and clear of the vehicle.
WARNING
●Make sure the parking brake is securely
applied and the manual transmission is
shifted into R (Reverse) , or the auto-
matic transmission into P (Park) .
● Never change tires when the vehicle is
on a slope, ice or slippery areas. This is
hazardous.
● Never change tires if oncoming traffic is
close to your vehicle. Wait for profes-
sional road assistance.

2. Place the jack directly under the jack-uppoint as illustrated so the top of the jack
contacts the vehicle at the jack-up point.
Align the jack head between the 2 notches in
the front or the rear as shown. Also fit the
groove of the jack head between the
notches as shown.
The jack should be used on firm and
level ground.
3. Install the assembled jack rod into the jackas shown.
4. To lift the vehicle, securely hold the jack lever and rod. Carefully raise the vehicle until the
tire clears the ground. 5. Remove the wheel nuts and then remove the
tire.

Installing the spare tire
The spare tire is designed for emergency
use. For additional information, refer to
“Wheels and tires” in the “Do-it-yourself”
section of this manual.1. Clean any mud or dirt from the surface be- tween the wheel and hub.
2. Carefully put the spare tire on and tighten the wheel nuts finger tight.
3. With the wheel nut wrench, tighten wheel nuts alternately and evenly in the sequence
illustrated (
1,2,3,4,5,6) until they
are tight. 4. Lower the vehicle slowly until the tire
touches the ground. Then, with the wheel
nut wrench, tighten the wheel nuts securely
in the sequence illustrated
(
1,2,3,4,5,6) . Lower the vehicle
completely .
WARNING
● Incorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.
● Do not use oil or grease on the wheel
studs or nuts. This could cause the nuts
to become loose.
● Retighten the wheel nuts when the ve-
hicle has been driven for 620 miles
(1,000 km) (also in cases of a flat tire,
etc.) .
As soon as possible, tighten the wheel nuts
to the specified torque with a torque
wrench.
Wheel nut tightening torque: 98 ft-lb (133 N·m)
The wheel nuts must be kept tightened to
specification at all times. It is recom- mended that wheel nuts be tightened to
specifications at each lubrication interval.
Adjust tire pressure to the COLD pressure.
COLD pressure: After vehicle has been
parked for 3 hours or more or driven less
than 1 mile (1.6 km) .
COLD tire pressures are shown on the Tire
and Loading Information label located in
the driver’s door opening.
5. Securely store the jacking equipment in the vehicle and the flat tire under the vehicle. For
additional information about storing the flat
tire, refer to “Getting the spare tire and tools”
in this section.
WARNING
●Always make sure that the spare tire
and jacking equipment are properly se-
cured after use. Such items can become
dangerous projectiles in an accident or
sudden stop.
● The spare tire is designed for emer-
gency use. For additional information,
refer to “Wheels and tires” in the “Do-
it-yourself” section of this manual.

In case of emergency6-11

CAUTION
●Never tow automatic transmission
models with the rear wheels on the
ground or four wheels on the ground
(forward or backward) , as this may
cause serious and expensive damage to
the transmission. If it is necessary to
tow the vehicle with the front wheels
raised always use towing dollies under
the rear wheels.
● When towing automatic or manual
transmission models with the front
wheels on the ground or on towing
dollies:
– Place the ignition switch in the OFF position, and secure the steering
wheel in a straight-ahead position
with a rope or similar device. Never
secure the steering wheel by placing
the ignition switch in the LOCK posi-
tion. This may damage the steering
lock mechanism (for models with a
steering lock mechanism) .
● If you have to tow manual transmission
models with the rear wheels on the
ground (if you do not use towing dol-
lies) or four wheels on the ground:
● Always release the parking brake. ●
Move the transmission shift lever to
the N (Neutral) position
● Observe the following restricted tow-
ing speeds and distances for manual
transmission models only:
Speed: Below 60 mph (97 km/h)
Distance: Less than 500 miles
(805 km)
When towing long distances or speeds in excess
of 60 mph (97 km/h), remove the propeller shaft
before towing to prevent damage to the transmis-
sion. It is recommended that you visit a NISSAN
dealer for more information.
VEHICLE RECOVERY (freeing a stuck
vehicle)

FLOOR MATS (if so equipped)
WARNING
To avoid potential pedal interference that
may result in a collision, injury or death:
●NEVER place a floor mat on top of an-
other floor mat in the driver front posi-
tion or install them upside down or
backwards.
● Use only Genuine NISSAN floor mats, or
equivalent floor mats, that are specifi-
cally designed for use in your vehicle
model and model year. ●
Properly position the mats in the floor-
well using the floor mat positioning
hook. For additional information, refer
to Floor mat installation in this
section.
● Make sure the floor mat does not inter-
fere with pedal operation.
● Periodically check the floor mats to
make sure they are properly installed.
● After cleaning the vehicle interior,
check the floor mats to make sure they
are properly installed.
The use of Genuine NISSAN floor mats can
extend the life of your vehicle carpet and make it
easier to clean the interior. Mats should be main-
tained with regular cleaning and replaced if they
become excessively worn.Floor mat installation
Your vehicle is equipped with floor mat position-
ing hook(s) . The number and shape of the floor
mat positioning hooks for each seating position
varies depending on the vehicle. When installing Genuine NISSAN floor mats,
follow the installation instructions provided with
the mat and the following:
1. Position the floor mat in the floorwell so that the floor mat grommet holes are aligned with
the hook(s) .
2. Secure the grommet holes into the hook(s) and ensure that the floor mat is properly
positioned.
3. Make sure the floor mat does not interfere with pedal operation. With the ignition in the
OFF position, the selector lever in the P
(Park) position (Automatic Transmission
models) or the shift lever in the N (Neutral)
position (Manual Transmission models) fully
apply and release all pedals. The floor mat
must not interfere with pedal operation or
prevent the pedal from returning to its nor-
mal position.
It is recommended that you visit a NISSAN dealer
for details about installing the floor mats in your
vehicle.
LAI0009
Appearance and care7-5

When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions which should be closely observed.
WARNING
●Park the vehicle on a level surface, ap-
ply the parking brake securely and
block the wheels to prevent the vehicle
from moving. Move the shift lever to P
(Park) .
● Be sure the ignition key is in the OFF or
LOCK position when performing any
parts replacement or repairs.
● If you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans, belts
and any other moving parts.
● It is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
● Always wear eye protection whenever
you work on your vehicle. ●
Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition key is in the OFF position 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. It
is recommended that you visit a
NISSAN dealer for this service because
the fuel lines are under high pressure
even when the engine is off.
CAUTION
●Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down. ●
Avoid contact with used engine oil and
coolant. Improperly disposed engine
oil, engine coolant and/or other vehicle
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid.
● Never leave the engine or the transmis-
sion related component harness con-
nector disconnected while the ignition
switch is in the ON position.
● Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
