check engine Acura TL 2004 Owner's Guide

Check the f luid level with the engine
at normal operating temperature.Park the vehicle on level ground.
Shut of f the engine.
Within 60 to 90 seconds, 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. Remove the dipstick, and check
the f luid level. It should be
between the upper and lower
marks.
If the level is below the lower
mark, add f luid into the f iller hole
to bring it to the upper mark.Always use Honda ATF-Z1
(Automatic Transmission Fluid). If
it’s not available, you may use a
DEXRON
III automatic
transmission f luid as a temporary
replacement. However, continued
use can af f ect the shif t quality.
Have the transmission flushed and
ref illed with Honda ATF-Z1 as
soon as it is convenient.
The transmission should be drained
and ref illed with new f luid when this
service is shown on a maintenance
message in the Multi-Information
Display. To thoroughly f lush the
transmission, the technician
should drain and ref ill it with
Honda ATF-Z1, then drive the
vehicle f or a short distance. Do
this three times. Then drain and
ref ill the transmission a f inal time.
Insert the dipstick all the way back
in the transmission.

Check the f luid level with the
transmission at normal operating
temperature and the vehicle sitting
on level ground. Remove the check
bolt, and look f or transmission f luid
coming out of the bolt hole. If a small
amount of f luid drips out of the bolt
hole, reinstall the check bolt.If Honda MTF is not available, you
may use an SAE 10W-30 or 10W-40
viscosity motor oil with the API
Certif ication seal that says ‘‘FOR
GASOLINE ENGINES’’ as a
temporary replacement. However,
motor oil does not contain the proper
additives, and continued use can
cause stiffer shifting. Replace as
soon as it is convenient. If no f luid comes out, remove the
f iller bolt. Slowly add Honda Manual
Transmission Fluid (MTF) until it
starts to run out of the check bolt
hole. Let the f luid run out until it
stops, then reinstall the check bolt
and the f iller bolt.
The transmission should be drained
and ref illed with new f luid when this

Check the brake f luid level in the
reservoirs monthly af ter removing
the engine compartment rear cover
(see page ).
Replace it every 3 years, independent
of mileage.
Always use Honda Heavy Duty
Brake Fluid DOT 3. If it is not
available, you should use only DOT 3
or DOT 4 f luid, f rom a sealed
container, as a temporary
replacement.The f luid level should be between
theMINandMAXmarksontheside
of the reservoir. If the level is at or
below the MIN mark, your brake
system needs attention. Have the
brake system inspected f or leaks or
worn brake pads.The f luid level should be between
theMINandMAXmarksontheside
of the reservoir. If it is not, add
brake f luid to bring it up to that level.
Use the same fluid specified for the
brake system.
A low f luid level can indicate a leak
in the clutch system. Have this
system inspected as soon as possible.
Brake f luid marked DOT 5 is not
compatible with your vehicle’s
braking system and can cause
extensive damage. Using any non-Honda brake f luid can
cause corrosion and decrease the lif e
of the system. Have the brake
system f lushed and ref illed with
Honda Heavy Duty Brake Fluid
DOT 3 as soon as possible. 203

Check the level on the side of the
reservoir when the engine is cold,
and the engine compartment right-
side cover is of f (see page ). The
f luid should be between the UPPER
LEVEL and LOWER LEVEL. If not,
add power steering f luid to the
UPPER LEVEL mark.Periodically clean the hood latch
assembly with a mild cleaner, then
lubricate it with a multipurpose
grease. Lubricate all the moving
parts (as shown), including the pivot.
If you are not sure how to do this,
contact your Acura dealer.
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.
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.

Diagnosing why the engine won’t
start f alls into two areas, depending
on what you hear when you turn the
key to START (III):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
START (III), you do not hear the
normal noise of the engine trying to
start. You may hear a clicking sound
or series of clicks, or nothing at all.
Turn the ignition switch to ON (II).
Turn on the headlights, and check
their brightness. If the headlights
are very dim or don’t light at all,
the battery is discharged. See on page . Turn the ignition switch to START
(III). If the headlights do not dim,
check the condition of the f uses. If
the f uses are OK, there is
probably something wrong with
the electrical circuit f or the
ignition switch or starter motor.
You will need a qualif ied
technician to determine the
problem (see
on page ).
Check these things:
If the headlights dim noticeably or
go out when you try to start the
engine, either the battery is dis-
charged 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).
Check the transmission interlock.
If you have a manual transmission,
the clutch pedal must be pushed
all the way to the f loor or the
starter will not operate. With an
automatic transmission, the shif t
lever must be in Park or Neutral.

In this case, the starter motor’s
speed sounds normal, or even f aster
than normal, when you turn the
ignition switch to START (III), 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 ).
Are you using the proper starting
procedure? Ref er to on page . There may be an electrical
problem, such as no power to the

Although this seems like a simple
procedure, you should take several
precautions.
Turn of f all the electrical acces-
sories: heater, A/C, stereo system,
lights, etc. Put the transmission in
Neutral or Park, and set the
parking brake.
Connect one jumper cable to the
positive ( ) terminal on your
battery. Connect the other end to
the positive ( ) terminal on the
booster battery.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.
You cannot start an Acura with an
automatic transmission by pushing
or pulling it. 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 like ice, do not try
jump starting until it thaws.

To Jump Start Your Vehicle:
238
NOTICE:
A battery can explode if you do
not follow the correct procedure,
seriously injuring anyone
nearby.
Keep all sparks, open flames,
and smoking materials away
from the battery. If a battery sits in extreme
cold, the electrolyte inside can f reeze.
Attempting to jump start with a f rozen
battery can cause it to rupture.

Start the engine and set the
interior temperature to maximum.
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 watch
the temperature gauge. If it goes
back to the red mark, the engine
needs repair (seeon 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.
Using gloves or 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.
If you don’t f ind an obvious leak,
check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark
(see
on
page ).
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. 8. 9.

Removing the radiator cap
while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and
radiator cool down before
removing the radiator cap.

Saf ely pull of f the road, and shut
of f the engine. Turn on the hazard
warning indicators.
If necessary, add oil to bring the
level back to the full mark on the
dipstick (see page ).
Start the engine, and watch the oil
pressure indicator. If it does not go
out within 10 seconds, turn of f the
engine. There is a mechanical
problem that needs to be repaired
bef ore you can continue driving
(seeon page
).
This indicator should never
come on when the engine is
running. If it starts f lashing
or stays on, the oil pressure has
dropped very low or lost pressure.
Serious engine damage is possible
and you should take immediate
action. Let the vehicle sit f or a minute.
Open the hood, and check the oil
level (see page ). An engine
very low on oil can lose pressure
during cornering and other driving
maneuvers. If the charging system
indicator comes on brightly
when the engine is running,
the battery is not being charged.
Immediately turn of f all electrical
accessories. Try not to use other
electrically operated controls such as
the power windows. Keep the engine
running; starting the engine will
discharge the battery rapidly.
Go to a service station or garage
where you can get technical
assistance.

mechanical damage almost immediately.
Turn of f the engine as soon as you can
saf ely get the vehicle stopped.

To check if they are set, turn the
ignition to ON (II), without starting
the engine. The Malf unction
Indicator Lamp will come on f or 20
seconds. If it then goes of f , the
readiness codes are set. If it blinks 5
times, the readiness codes are not
set. If possible, do not take your
vehicle f or a state emissions test
until the readiness codes are set.
Refer to State Emissions Testing for
more information (see page ).
If the indicator comes on
while driving, it means one
of the engine’s emissions
control systems may have a problem.
Even though you may f eel no
dif f erence in your vehicle’s
perf ormance, it can reduce your f uel
economy and cause increased
emissions. Continued operation may
cause serious damage.
If you have recently ref ueled your
vehicle, the indicator coming on
could be a loose or missing f uel f ill
cap. Tighten the cap until it clicks at
least three times. Tightening the cap
will not turn the indicator of f
immediately; it takes at least three
days of normal driving. If the indicator comes on repeatedly,
even though it may go of f as you
continue driving, have the vehicle
checked by the dealer as soon as
possible.
Your vehicle has certain ‘‘readiness
codes’’ that are part of the on-board
diagnostics f or the emissions
systems. In some states, part of the
emissions testing is to make sure
these codes are set. If they are not
set, the test cannot be completed.If your vehicle battery has been
disconnected or gone dead, these
codes are erased. If takes at least
three days of normal driving to set
the codes again.
