2011 HONDA PILOT check engine

If the reserve tank is completely
empty, you should also check the
coolant level in the radiator.
If the coolant level in the reserve
tank is at or below the MIN line, add
coolant to bring it up to the MAX line.
Inspect the cooling system f or leaks. Always use Honda Long-lif e Anti-
f reeze/Coolant Type 2. This coolant
is pre-mixed with 50 percent
antif reeze and 50 percent distilled
water. Never add straight antif reeze
or plain water.
If Honda antif reeze/coolant is not
available, you may use another
major-brand non-silicate coolant as a
temporaryreplacement.Makesureit
is a high-quality coolant
recommended f or aluminum engines.
Continued use of any non-Honda
coolant can result in corrosion,
causing the cooling system to
malf unction or f ail. Have the cooling
system f lushed and ref illed with
Honda antif reeze/coolant as soon as
possible.

Check the f luid level in the
windshield washer reservoir at least
monthly during normal use.Fill the reservoir with a good-quality
windshield washer f luid. This
increases the cleaning capability and
prevents f reezing in cold weather.
When you ref ill the reservoir, clean
the edges of the windshield wiper
blades with windshield washer f luid
on a clean cloth. This will help to
condition the blade edges.
Check the f luid level by removing
the cap and looking at the level
gauge.
The washer level indicator will come
on when the level is low (see page
).
If the washer f luid is low, a ‘‘LOW
WASHER FLUID’’ message appears
on the multi-information display. 80

Do not use engine antif reeze or a
vinegar/water solution in the
windshield washer reservoir. Antif reeze
can damage your vehicle’s paint, while
a vinegar/water solution can damage
the windshield washer pump. Use only
commercially-available windshield
washer f luid.

Remove the dipstick (yellow loop)
f rom the transmission, and wipe it
with a clean cloth.Insert the dipstick all the way into
the transmission securely as
shown in the illustration.
Remove the dipstick and check
the f luid level. It should be
between the upper and lower
marks.
Check the f luid level with the engine
at normal operating temperature.
Park the vehicle on level ground.
Start the engine, let it run until the
radiator f an comes on, then shut
of f the engine. For accurate
results, wait about 60 seconds (but
no longer than 90 seconds) bef ore
doing step 2.
The transmission should be drained
and ref illed with new f luid when this
service is shown on the inf ormation
display or multi-inf ormation display
(depending on models).

Check the level on the side of the
reservoir when the engine is cold.
The f luid should be between the
UPPER LEVEL and LOWER LEVEL.
If not add power steering f luid to the
UPPER LEVEL mark. Always use Honda Power Steering
Fluid. You may use another power
steering f luid as an emergency
replacement, but have the power
steering system f lushed and ref illed
with Honda PSF as soon as possible.
The timing belt should be replaced
at the intervals shown in the
maintenance inf ormation schedule.
A low power steering f luid level can
indicate a leak in the system. Check
the f luid level f requently, and have
the system inspected as soon as
possible.
If you are not sure how to add
f luid, contact your dealer.
Pour the f luid slowly and caref ully so
you do not spill any. Clean up any
spills immediately; it could damage
components in the engine
compartment. Replace the timing belt every 60,000
miles (U.S.) or every 100,000 km
(Canada) if you regularly drive your
vehicle in any of the f ollowing
conditions:
In very high temperatures
(over 110°F, 43°C).
In very low temperatures
(under 20°F, 29°C).

Diagnosing why the engine won’t
start f alls into two areas, depending
on what you hear when you turn the
ignition switch to the START (III)
position:You hear nothing, or almost
nothing. The engine’s starter
motor does not operate at all, or
operates very slowly.
You can hear the starter motor
operating normally, or the starter
motor sounds like it is spinning
f aster than normal, but the engine
does not start up and run.
When you turn the ignition switch to
the START (III) position, you do not
hear the normal noise of the engine
trying to start. You may hear a
clicking sound, a series of clicks, or
nothing at all. If the headlights dim noticeably or
go out when you try to start the
engine, either the battery is
discharged or the connections are
corroded. Check the condition of
the battery and terminal connec-
tions (see page ). You can
then try jump starting the vehicle
f rom a booster battery (see page
).
In this case, the starter motor’s
speed sounds normal, or even f aster
than normal, when you turn the
ignition switch to the START (III)
position, but the engine does not run. Are you using a properly coded
key? An improperly coded key will
cause the immobilizer system
indicator in the instrument panel
to blink rapidly (see page ).
Check these things:
Check the transmission interlock.
The transmission must be in Park
or neutral or the starter will not
operate.
Turn the ignition switch to the ON
(II) position. Turn on the
headlights, and check their
brightness. If the headlights are
very dim or do not come on at all,
the battery is discharged. See on page .
Turn the ignition switch to the
START (III) position. If the
headlights do not dim, check the
condition of the f uses. If the f uses
areOK,thereisprobably
something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualif ied technician to
determine the problem. See on page .517

Put the transmission in neutral or
Park, and set the parking brake. Turn of f all the electrical acces-
sories: heater, A/C, climate
control, audio system, lights, etc. Open the hood, and check the
physical condition of the battery.
In very cold weather, check the
condition of the electrolyte. If it
seems slushy or f rozen, do not try
jump starting until it thaws.

´ ´ Start your vehicle. If the starter
motor still operates slowly, check
that the jumper cables have good
metal-to-metal contact. If the booster battery is in another
vehicle, have an assistant start
that vehicle and run it at a fast idle.
Connect the second jumper cable
to the negative ( ) terminal on
the booster battery. Connect the
other end to the grounding strap
as shown. Do not connect this
jumper cable to any other part of
the engine.
The numbers in the illustration show
you the order to connect the jumper
cables.
Connect one jumper cable to the
positive ( ) terminal on your
vehicle’s battery. Connect the
other end to the positive ( )
terminal on the booster battery. Once the vehicle is running,
disconnect the negative cable f rom
your vehicle, then f rom the
booster battery. Disconnect the
positive cable f rom your vehicle,
and then from the booster battery.
Keep the ends of the jumper cables
away from each other and any metal
on the vehicle until everything is
disconnected. Otherwise, you may
cause an electrical short. 5.

If the temperature gauge stays at
the red mark, turn of f the engine.
Look f or any obvious coolant leaks,
such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you f ind a leak, it
must be repaired bef ore you
continue driving (seeon page ).
If you do not f ind an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark.
If there was no coolant in the
reserve tank, you may need to add
coolant to the radiator. Let the
engine cool down until the pointer
reaches the middle of the tempera-
ture gauge, or lower, bef ore check-
ing the radiator. Using gloves or a large heavy
cloth, turn the radiator cap
counterclockwise, without pushing
down, to the f irst stop. Af ter the
pressure releases, push down on
the cap, and turn it until it comes
off.Start the engine, and set the
temperature to maximum heat
(climate control to AUTO at
‘‘ ’’). Add coolant to the
radiator up to the base of the f iller
neck. If you do not have the
proper coolant mixture available,
you can add plain water.
Remember to have the cooling
system drained and ref illed with
the proper mixture as soon as you
can.
Put the radiator cap back on
tightly. Run the engine, and check
the temperature gauge. If it goes
back to the red mark, the engine
needs repair (see
on page ).
If the temperature stays normal,
check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the
MAX mark. Put the cap back on
tightly.
