check engine NISSAN TITAN 2023 Manual PDF

Exhaust system:Visually inspect the ex-
haust pipes, muffler and hangers for leaks,
cracks, deterioration and damage. Tighten
connections or replace parts as necessary.
For additional information, see “Exhaust
gas (carbon monoxide)” (P. 5-4).
Fluid leaks: Check under the vehicle for
fuel, oil, water or other fluid leaks af ter the
vehicle has been parked for a while. Water
dripping from the air conditioner af ter use
is normal. If you should notice any leaks or if
fuel fumes are evident, check for the cause
and have it corrected immediately.
Power steering fluid level* and lines:
Check the level when the fluid is cold, with
the engine off. Check the lines for proper
attachment, leaks, cracks, etc.
Radiator and hoses Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, defor-
mation, rot or loose connections. Underbody:
The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances from the underbody, otherwise
rust may form on the floor pan, frame, fuel
lines and exhaust system. At the end of
winter, the underbody should be thor-
oughly flushed with plain water, in those
areas where mud and dirt may have accu-
mulated. For additional information, see
“Cleaning exterior” (P. 7-2).
Windshield-washer fluid*: Check that
there is adequate fluid in the reservoir. The following descriptions are provided to
give you a better understanding of the
scheduled maintenance items that should
be regularly checked or replaced. The
maintenance schedule indicates at which
mileage/time intervals each item requires
service.
Items marked with
“*”are recommended
by NISSAN for reliable vehicle operation.
You are not required to perform mainte-
nance on these items in order to maintain
the warranties which come with your
NISSAN. Other maintenance items and in-
tervals are required.
When applicable, additional information
can be found in the “Do-it-yourself ” section
of this manual.
NOTE: NISSAN does not advocate the use
of non-OEM approved af termarketflushing systems and strongly advisesagainst performing these services on aNISSAN product. Many of the af termar-ket flushing systems use non-OEM ap-proved chemicals or solvents, the use ofwhich has not been validated by NISSAN.
For recommended fuel, lubricants, fluids,
grease, and refrigerant, see “Recom-
mended fluids/lubricants and capacities”
(P. 10-2).
EXPLANATION OF SCHEDULED
MAINTENANCE ITEMS

EMISSION CONTROL SYSTEM
MAINTENANCE:
Engine Drive Belts*:Check engine drive
belts for wear, fraying or cracking and for
proper tension. Replace any damaged
drive belts.
Engine Air Filter: Replace at specified in-
tervals. When driving for prolonged periods
in dusty conditions, check/replace the filter
more frequently.
Engine Coolant*: Replace coolant at the
specified interval. When adding or replac-
ing coolant, be sure to use only Genuine
NISSAN Long Life Antifreeze/Coolant (blue)
or equivalent with the proper mixture. (For
additional information on the proper mix-
ture for your area, see “Engine cooling sys-
tem” (P. 8-7)).
NOTE: Mixing any other type of coolant or
the use of non-distilled water may reduce
the recommended service interval of the
coolant.

specified intervals.
If towing a trailer, using a camper or car-top
carrier, or driving on rough or muddy roads:
• Replace the differential oil every 20,000 miles (32,000 km) or 24 months.
• Replace the automatic transmission fluid ever 30,000 miles (48,000 km) or 24
months.
9-6Maintenance and schedules

Off-Road Maintenance:Check the follow-
ing items frequently whenever you drive
off-road through deep sand, mud or water:
• Brake pads and rotors
• Brake lines and hoses
• Differential, transmission and transfer case oil
• Steering linkage
• Propeller shaf t(s) and front drive shaf ts
• Engine air filter
• Clutch housing drain (4WD only) To help ensure smooth, safe and economi-
cal driving, NISSAN provides two mainte-
nance schedules that may be used, de-
pending upon the conditions in which you
usually drive. These schedules contain
both distance and time intervals, up to
120,000 miles (192,000 km)/96 months. For
most people, the odometer reading will in-
dicate when service is needed. However, if
you drive very little, your vehicle should be
serviced at the regular time intervals
shown in the schedule.
Af ter 120,000 miles (192,000 km)/96
months, continue maintenance at the
same mileage/time intervals.
ADDITIONAL MAINTENANCE ITEMS
FOR SEVERE OPERATING
CONDITIONS
Additional maintenance items for severe
operating conditions
should be per-
formed on vehicles that are driven under
especially demanding conditions. Addi-
tional maintenance items should be per-
formed if you primarily operate your vehicle
under the following conditions:
• Repeated short trips of less than 5 miles in normal temperatures or less than 10
miles in freezing temperatures. • Stop-and-go traffic in hot weather or low
speed driving for long distances.
• Driving in dusty conditions or on rough, muddy or salt-spread roads.
• Towing a trailer, or using a camper or car- top carrier.
If your vehicle is mainly operated under the
severe conditions, follow the severe use
maintenance intervals shown in the main-
tenance schedule.

Maintenance and schedules9-7

Af termarket fuel additives
NISSAN does not recommend the use of
any af termarket fuel additives (for ex-
ample, fuel injector cleaner, octane
booster, intake valve deposit removers,
etc.) which are sold commercially. Many of
these additives intended for gum, varnish
or deposit removal may contain active sol-
vents or similar ingredients that can be
harmful to the fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended can
cause persistent, heavy “spark knock.”
(“Spark knock” is a metallic rapping
noise.) If severe, 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, it is recom-
mended that you have a NISSAN dealer
correct the condition. Failure to correct
the condition is misuse of the vehicle, for
which NISSAN is not responsible.Incorrect ignition timing may result in
spark knock, af ter-run and/or overheating,
which may cause excessive fuel consump-
tion or engine damage. If any of the above
symptoms are encountered, have your ve-
hicle checked. It is recommended that you
visit a NISSAN dealer for servicing.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is not
a cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.
10-6Technical and consumer information

• Use the Tow Mode or downshif t thetransmission to a lower gear for engine
braking when driving down steep or long
hills. This will help slow the vehicle without
applying the brakes.
• Avoid holding the brake pedal down too long or too frequently. This could cause
the brakes to overheat, resulting in re-
duced braking efficiency.
• Increase your following distance to allow for greater stopping distances while tow-
ing a trailer. Anticipate stops and brake
gradually.
• NISSAN recommends that the cruise control (if so equipped) not be used while
towing a trailer.
• While towing a trailer, do not use the fol- lowing systems (if so equipped):–– the Lane Departure Warning (LDW) system
–– the Blind Spot Warning (BSW) system
– – the Intelligent Cruise Control (ICC)
system
– – the Automatic Emergency Braking
(AEB) system
– – the Intelligent Forward Collision
Warning (I-FCW) system
– – the Rear Automatic Braking (RAB)
system –
– the Moving Object Detection (MOD)
system
– – the Cross Traffic Alert system
–– the Rear Sonar system
• Some states or provinces have specific regulations and speed limits for vehicles
that are towing trailers. Obey the local
speed limits.
• Check your hitch, trailer wiring harness connections, and trailer wheel lug nuts
af ter 50 miles (80 km) of travel and at
every break.
• When launching a boat, don't allow the water level to go over the exhaust tail
pipe or rear bumper.
• Make sure you disconnect the trailer lights before backing the trailer into the
water or the trailer lights may burn out.
When towing a trailer, final drive gear oil
should be replaced and transmission oil/
fluid should be changed more fre-
quently. For additional information, see
the “Do-it-yourself ” section of this
manual.Tow mode
Using tow mode is recommended when
pulling a heavy trailer or hauling a heavy
load. Press the TOW MODE switch to acti-
vate tow mode. The indicator light on the
TOW MODE switch illuminates when tow
mode is selected. Press the TOW MODE
switch again to turn tow mode off. Tow
mode is automatically canceled when the
ignition switch is turned off.
Tow mode includes the following features:
• Grade logic — Adjusts transmission shif ts when pulling a trailer or hauling a load up
a grade.
• Downhill Speed Control (DSC) — auto- matically downshif ts when driving down
a grade with a trailer or heavy load to help
control vehicle speed.
Driving the vehicle in the tow mode with no
trailer/load or light trailer/light load will not
cause any damage. However, fuel
economy may be reduced and the
transmission/engine driving characteris-
tics may feel unusual.
10-52Technical and consumer information

WARNING
A vehicle equipped with 4-Wheel Drive
(4WD) should never be tested using a
two wheel dynamometer (such as the
dynamometers used by some states
for emissions testing), or similar equip-
ment. Make sure you inform the 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 transmis-
sion damage or unexpected vehicle
movement which could result in seri-
ous vehicle damage or personal injury.
Due to legal requirements in some states
and Canadian Provinces, your vehicle may
be required to be in what is called the
“ready condition” for an Inspection/
Maintenance (I/M) test of the emission
control system.
The vehicle is set to the “ready condition”
when it is driven through certain driving
patterns. Usually, the ready condition can
be obtained by ordinary usage of the
vehicle. If a powertrain system component is re-
paired or the battery is disconnected, the
vehicle may be reset to a “not ready” condi-
tion. Before taking the I/M test, check the
vehicle's inspection/maintenance test
readiness condition. Place the ignition
switch in the ON position without starting
the engine. If the Malfunction Indicator
Light (MIL) comes on steady for 20 seconds
and then blinks for 10 seconds, the I/M test
condition is “not ready”. If the MIL does not
blink af ter 20 seconds, the I/M test condi-
tion is “ready”. It is recommended that you
visit a NISSAN dealer to set the “ready con-
dition” or to prepare the vehicle for testing.
This vehicle is equipped with an Event Data
Recorder (EDR). The main purpose of an
EDR is to record, in certain crash or near
crash-like situations, such as an air bag
deployment or hitting a road obstacle, data
that will assist in understanding how a ve-
hicle's systems performed. The EDR is de-
signed to record data related to vehicle dy-
namics and safety systems for a short
period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to re-
cord such data as:
• How various systems in your vehicle were
operating;
• Whether or not the driver and passenger safety belts were buckled/fastened;
• How far (if at all) the driver was depress- ing the accelerator and/or brake pedal;
and,
• How fast the vehicle was traveling.
• Sounds are not recorded.
