2004 CHEVROLET MALIBU check engine light

Remote Vehicle Start
Your vehicle may have a remote starting feature. This
feature allows you to start the engine from outside of the
vehicle. It also starts up the vehicle’s heating or air
conditioning systems and rear window defogger. When
the remote start system is active and the vehicle
has an automatic climate control system, it will
automatically regulate the inside temperature. Normal
operation of the system will return after the key is turned
to the on position. A remote start occurs when buttons
on the remote keyless entry transmitter are pressed.
Laws in some local communities require that a person
using remote start have the vehicle in view when
doing so and may prohibit the execution of remote start
if not in view of the vehicle. Check local regulations
for any requirements on remote starting of vehicles.
Do not use the remote start feature if your vehicle is low
on fuel. Your vehicle may run out of fuel.
The remote start feature provides two separate starts,
each with 10 minutes of engine running. Or it provides
one start with 10 minutes of engine running, which can be
extended by 10 more minutes, for 20 minutes of total
running time. Once two starts or 20 minutes running time
has been provided, the vehicle must be started normally
with the ignition key to get more remote starts.The remote start feature will not operate if the key is in
the ignition or the hood is not closed.
Your remote keyless entry transmitter, with the remote
start button, provides an increased range of operation.
However, the range may be less while the vehicle
is running. As a result, you may need to be closer to
your vehicle to turn it off, than you were to turn it on.
There are other conditions which can affect the
performance of the transmitter, see “Remote Keyless
Entry System Operation” previously in this section.
/(Remote Start):Press the lock button and then
press this button to use the remote start feature.
To start the vehicle using the remote start feature, do
the following:
1. Aim the transmitter at the vehicle.
2. Press the transmitter’s lock button, release it and
then immediately press and hold the transmitter’s
remote start button until the vehicle’s turn signal
lights ash or for at least four seconds. The
vehicle’s doors will be locked.
3. When the vehicle starts, the parking lamps will turn
on and remain on while the vehicle is running.
4. If it is your rst remote start since last driving,
repeat these steps while the engine is still
running for a 10 minute time extension.

PASS-Key®III+
Your PASS-Key®III + system operates on a radio
frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. this device may not cause harmful interference, and
2. this device must accept any interference received,
including interference that may cause undesired
operation.
This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. this device may not cause interference, and
2. this device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modications to this system by other than
an authorized service facility could void authorization to
use this equipment.
PASS-Key
®III + uses a radio frequency transponder in
the key that matches a decoder in your vehicle.
PASS-Key®III+ Operation
Your vehicle is equipped with PASS-Key®III +
(Personalized Automotive Security System)
theft-deterrent system. PASS-Key
®III + is a passive
theft-deterrent system. This means you don’t have to do
anything special to arm or disarm the system. It works
when you insert or remove the key from the ignition.
When the PASS-Key
®III + system senses that someone
is using the wrong key, it shuts down the vehicle’s starter
and fuel systems. The starter will not work and fuel will
stop owing to the engine. Anyone using a trial-and-error
method to start the vehicle will be discouraged because
of the high number of electrical key codes.
When trying to start the vehicle if the engine does not
start and the SECURITY light in the instrument
panel cluster comes on, the key may have a damaged
transponder. Turn the ignition off and try again.
If the engine still does not start, and the key appears to
be undamaged, try another ignition key. At this time,
you may also want to check the fuse, seeFuses
on page 5-88. If the engine still does not start with the
other key, your vehicle needs service. If your vehicle
does start, the rst key may be faulty. See your dealer
who can service the PASS-Key
®III + to have a new
key made. In an emergency, contact Chevrolet Roadside
Assistance. SeeRoadside Assistance Program on
page 7-6for more information.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages that may
be on your vehicle. The pictures will help you locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to your
warning lights and gages could also save you or others
from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you will
see in the details on the next few pages, some warning
lights come on briey when you start the engine just to let
you know they are working. If you are familiar with this
section, you should not be alarmed when this happens.Gages can indicate when there may be or is a
problem with one of your vehicle’s functions. Often
gages and warning lights work together to let you
know when there is a problem with your vehicle.
When one of the warning lights comes on and stays
on when you are driving, or when one of the gages
shows there may be a problem, check the section
that tells you what to do about it. Please follow this
manual’s advice. Waiting to do repairs can be
costly — and even dangerous. So please get to
know your warning lights and gages. They are
a big help.
3-31

{CAUTION:
If the air bag readiness light stays on after
you start your vehicle, it means the air bag
system may not be working properly. The air
bags in your vehicle may not inate in a crash,
or they could even inate without a crash.
To help avoid injury to yourself or others,
have your vehicle serviced right away if the
air bag readiness light stays on after you
start your vehicle.
The air bag readiness light should ash for a few
seconds when you turn the ignition key to ON.
If the light doesn’t come on then, have it xed so
it will be ready to warn you if there is a problem.
Charging System Light
The charging system light
will come on when you
turn on the ignition, but
the engine is not running,
as a check to show
you it is working.
When the engine is running, the light should go out.
If it stays on, or comes on while you are driving and
you hear a chime, you may have a problem with
the electrical charging system. It could indicate that you
have a loose generator drive belt or another electrical
problem. Have it checked right away. Driving while
this light is on could drain your battery.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such as the
radio and air conditioner.
3-35

Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
If the gage pointer moves into the red area, the light
comes on and you hear a chime, your engine is too hot!
It means that your engine coolant has overheated.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
SeeEngine Overheating on page 5-27.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment. The Check Engine light comes on
to indicate that there is a problem and service is
required. Malfunctions often will be indicated by the
system before any problem is apparent. This may
prevent more serious damage to your vehicle.
This system is also designed to assist your service
technician in correctly diagnosing any malfunction.
Notice:If you keep driving your vehicle with this
light on, after a while, your emission controls may
not work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty. United States
Canada
3-39

Notice:Modications made to the engine,
transaxle, exhaust, intake or fuel system of your
vehicle or the replacement of the original tires with
other than those of the same Tire Performance
Criteria (TPC) can affect your vehicle’s emission
controls and may cause this light to come on.
Modications to these systems could lead to costly
repairs not covered by your warranty. This may
also result in a failure to pass a required Emission
Inspection/Maintenance test.
This light should come on, as a check to show you
it is working, when the ignition is on and the engine
is not running. If the light does not come on, have
it repaired. This light will also come on during a
malfunction in one of two ways:
Light Flashing— A misre condition has been
detected. A misre increases vehicle emissions
and may damage the emission control system
on your vehicle. Diagnosis and service may
be required.
Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service may be required.
If the Light is Flashing
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed.
Avoiding hard accelerations.
Avoiding steep uphill grades.
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops ashing and remains on steady,
see “If the Light Is On Steady” following.
If the light continues to ash, when it is safe to do so,
stop the vehicle.Find a safe place to park your
vehicle. Turn the key off, wait at least 10 seconds
and restart the engine. If the light remains on steady,
see “If the Light Is On Steady” following. If the light
is still ashing, follow the previous steps, and see your
dealer for service as soon as possible.
3-40

If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully
install the cap. SeeFilling Your Tank on page 5-8.
The diagnostic system can determine if the fuel cap has
been left off or improperly installed. A loose or missing
fuel cap will allow fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light off.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
SeeGasoline Octane on page 5-5. Poor fuel quality will
cause your engine not to run as efficiently as designed.
You may notice this as stalling after start-up, stalling
when you put the vehicle into gear, misring, hesitation
on acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the
light to turn on.If you experience one or more of these conditions,
change the fuel brand you use. It will require at least
one full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
your dealer can check the vehicle. Your dealer has the
proper test equipment and diagnostic tools to x any
mechanical or electrical problems that may have
developed.
Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this inspection
could prevent you from getting a vehicle registration.
Here are some things you need to know to help your
vehicle pass an inspection:
Your vehicle will not pass this inspection if the Check
Engine light is on or not working properly.
Your vehicle will not pass this inspection if the
OBD (on-board diagnostic) system determines that
critical emission control systems have not been
completely diagnosed by the system. The vehicle
would be considered not ready for inspection.
3-41

This can happen if you have recently replaced your
battery or if your battery has run down. The diagnostic
system is designed to evaluate critical emission
control systems during normal driving. This may take
several days of routine driving. If you have done this and
your vehicle still does not pass the inspection for lack
of OBD system readiness, your GM dealer can prepare
the vehicle for inspection.
Oil Pressure Light
If you have a low engine
oil pressure problem,
this light will stay on after
you start your engine,
or come on and you will
hear a chime when you
are driving.
This indicates that your engine is not receiving enough
oil. The engine could be low on oil, or could have
some other oil problem. Have it xed immediately.When the ignition is on but the engine is not running,
the light will come on as a test to show you it is working,
but the light will go out when the engine is running.
If it doesn’t come on with the ignition on, you may have
a problem with the bulb. Have it xed right away.
{CAUTION:
Do not keep driving if the oil pressure is low.
If you do, your engine can become so hot that
it catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would not
be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.
