check engine Acura RSX 2004 Owner's Guide

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. Follow the time
and distance recommendations in
the Maintenance Schedule. If you
are not sure how to clean and grease
the latch, contact your Acura dealer.
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.
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.

T urning the steering wheel to
f ull lef t or right lock and holding it
there can damage the power steering
pump.
Do not spill the power
steering f luid over the body, auto-
tensioner, drive belt and pulleys.
If spilled accidentally, wipe of f any
f luid completely.

Store the tool kit.
Store the wheel cover or center
cap in the cargo area. Make sure it
will not get scratched or damaged.Diagnosing why your 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.
Check these things:
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, it must be
in Park or Neutral.
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 .
Reinstall the f loor mat and spare
tire cover, then close the hatch.

Loose items can fly around the
interior in a crash and could
seriously injure the occupants.
Store the wheel, jack, and tools
securely before driving.

Turn the ignition switch to START
(III). If the headlights do not dim,
check the condition of the f uses. If
thefusesareOK,thereis
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 ).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 .
Do you have f uel? Check the f uel
gauge; the low f uel indicator may
not be working. There may be an electrical
problem, such as no power to the
f uel pump. Check all the f uses
(see page ).
If youfindnothingwrong,youwill
need a qualif ied technician to f ind
the problem. See on page .
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
connections (see page ). You

Start your vehicle. If the starter
motor still operates slowly, check
the jumper cable connections to
make sure they have good metal-
to-metal contact.
Once your 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.
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.
If the booster battery is in another
vehicle, have an assistant start
that vehicle and run it at a fast idle.
The numbers in the illustration show
you the order to connect the jumper
cables.

BOOSTER BATTERY

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 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.
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 large heavy cloth,
turn the radiator cap
counterclockwise without pushing
down to the first stop. After the
pressure releases, push down on
the cap, and turn it until it comes
off.Start the engine, and set the
temperature control lever 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 (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.

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.

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
).
Saf ely pull of f the road, and shut
of f the engine. Turn on the hazard
warning indicators.
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 necessary, add oil to bring the
level back to the full mark on the
dipstick (see 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. 1.

NOTICE:
Running the engine with low
oil pressure can cause serious
mechanical damage almost immediately.
Turn of f the engine as soon as you can
saf ely get the vehicle stopped.

If you have recently ref ueled your
vehicle, the cause of this indicator
coming on could be a loose or
missing f uel f ill cap. Check the cap
or replace it. Tightening the cap will
not make the indicator turn of f
immediately; it takes at least three
days of normal driving.
If the indicator remains on, or the
f uel cap was not loose or missing,
have your vehicle checked by the
dealer as soon as possible.
If the indicator comes on
while driving, it means one
of the engine’s emission control
systems may have a problem. Even
though you may f eel no dif f erence in
your vehicle’s perf ormance,
continued operation may cause
serious damage.

NOTICE: If you keep driving with the
Malf unction Indicator Lamp on, you
can damage your vehicle’s emissions
controls and the engine. Those repairs
may not be covered by your vehicle’s
warranties.

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’s battery has been
disconnected or gone dead, these
codes are erased. It takes several
days of driving under various
conditions to set the codes again.To check if they are set, turn the
ignition switch to ON (II), without
starting the engine. The Malf unction
Indicator Lamp will come on f or 20
seconds.If itthengoesoff,the
readiness codes are set. If it blinks
f ive 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. See
State Emissions Testing on pages
