engine CHEVROLET CORVETTE 2006 6.G Service Manual

If the light comes on while you are driving and you have
a CHECK BRAKE FLUID message showing on the
DIC, pull off the road and stop carefully. You may notice
that the pedal is harder to push or the pedal may go
closer to the oor. It may take longer to stop. If the light
is still on, have the vehicle towed for service. See
Towing Your Vehicle on page 4-38andDIC Warnings
and Messages on page 3-53for more information.
{CAUTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on after you
have pulled off the road and stopped carefully,
have the vehicle towed for service.
Anti-Lock Brake System
Warning Light
With the anti-lock brake
system, the light will come
on when your engine is
started and may stay on
for several seconds.
That is normal.
If the light stays on, turn the ignition off. Or, if the light
comes on when you are driving, stop as soon as
possible and turn the ignition off. Then start the engine
again to reset the system. If the light still stays on,
or comes on again while you are driving, your vehicle
needs service. If the regular brake system warning light
is not on, you still have brakes, but you do not have
anti-lock brakes. If the regular brake system warning
light is also on, you do not have anti-lock brakes
and there is a problem with your regular brakes. See
“SERVICE ANTILOCK BRAKES” underDIC Warnings
and Messages on page 3-53.
The anti-lock brake system warning light will come on
briey when you turn the ignition on. This is normal.
If the light does not come on then, have it xed so it will
be ready to warn you if there is a problem.

Traction Control System (TCS)
Warning Light
This light should come on
briey as you start the
engine. If the light does not
come on then, have it xed
so it will be ready to warn
you if there is a problem.
If it stays on, or comes on and the DIC shows a SERVICE
TRACTION SYSTEM message when you are driving,
there is a problem with your TCS system and your vehicle
needs service. When this light is on, the system will not
limit wheel spin. Adjust your driving accordingly. If the
driver turns off the Traction Control System by pressing
the button on the console, the TCS system light will come
on and the TRACTION SYSTEM OFF message will show
on the DIC. SeeDIC Warnings and Messages on
page 3-53for more information.
Active Handling System Light
The Active Handling System light will come on briey
as you start the engine. If the light does not come
on then, have it xed so it will be ready to warn you if
there is a problem. This light will also come on when
the ACTIVE HANDLING CALIBRATING message
is displayed in the Driver Information Center (DIC).
If the light stays on or
comes on while you are
driving, a chime sounds
and a SERVICE ACTIVE
HANDLING SYSTEM
message appears on the
DIC, there is a problem
with your Active Handling
System and your vehicle
needs service.
The driver can acknowledge this message by pressing
the RESET button. When the SERVICE ACTIVE
HANDLING SYSTEM message is displayed in the DIC,
the Active Handling System will not assist you in
controlling the vehicle. You should have the system
serviced as soon as possible. Adjust your driving
accordingly.
3-40

When the system is working, you will see the ACTIVE
HANDLING message displayed in the DIC. You may also
feel or hear the system working. This is normal.
If the driver turns off the Active Handling System by
pressing the button on the console for ve seconds, the
Active Handling System light will come on, a chime
will sound, and the TRACTION SYSTEM AND ACTIVE
HANDLING – OFF message will be displayed in the
DIC. The Traction Control System will also be turned off.
SeeDIC Warnings and Messages on page 3-53for
more information.
If the Active Handling System and the Traction Control
System are off, pressing the console button momentarily
will turn both systems on. The DIC will display the
TRACTION SYSTEM AND ACTIVE HANDLING – ON
message, the instrument cluster light will be off, and
a chime will sound. SeeDIC Warnings and Messages
on page 3-53for more information.Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
If the gage pointer moves into the shaded area, your
engine is too hot.
This 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.

Tire Pressure Light
This light should come on
briey as you start the
engine. It will then come on
only when a at or low tire
pressure condition exists.
SeeTire Pressure Monitor System on page 5-67for
more information.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle has 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 awhile, 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.
Notice:Modications made to the engine,
transmission, 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. SeeAccessories
and Modifications on page 5-3.

This light should come on briey, as a check to show
you it is working, as you start the engine. 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 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 engine 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.
If the Light Is On Steady
You also 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 the Tank on page 5-7. 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.
3-43

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.
To perform a Check Engine light bulb check with the
keyless ignition, make sure the transmitter fob is in the
passenger compartment. SeeIgnition Positions on
page 2-22. Press the bottom of the ACC button on the
instrument panel and hold the button down for ve
seconds. The instrument panel, including the Check
Engine light, will light up and the ignition will be on, but
the engine will not start — if you press the bottom of
the ACC button only briey, less than ve seconds, the
accessory power mode will be turned on, but not the
ignition. After the bulb check, be sure to press and
release the ACC button again to turn the ignition off and
avoid draining the vehicle’s battery.
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. 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.
3-44

Engine Oil Pressure GageThe engine oil pressure gage shows the engine oil
pressure in psi (pounds per square inch) or kPa
(kilopascals) when the engine is running.
Oil pressure should be 20 to 80 psi (140 to 550 kPa).
In certain situations such as long, extended idles on hot
days, it could read as low as 6 psi (40 kPa) and still
be considered normal. It may vary with engine speed,
outside temperature and oil viscosity, but readings
above the shaded area show the normal operating
range. Readings in the shaded area tell you that the
engine is low on oil, or that you might have some other
oil problem. SeeEngine Oil on page 5-16.
The engine oil pressure can also be displayed using the
GAGES button on the Driver Information Center (DIC).
SeeDriver Information Center (DIC) on page 3-48.
{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. United States

Fuel Gage
Your fuel gage tells you
about how much fuel
you have left when
the engine is on.
When the needle approaches the low fuel symbol, a
chime will sound and LOW FUEL will appear on the
Driver Information Center (DIC) display. At this time, you
still have a little fuel left, but you should get more soon.
Press the RESET button to acknowledge a DIC
message(s). Pressing the RESET button will also turn
off a DIC message but the LOW FUEL message
will come on again in 10 minutes if you have not added
fuel to the vehicle.Here are ve things that some owners ask about.
All these things are normal and do not indicate that
anything is wrong with the fuel gage.At the gas station, the gas pump shuts off before
the gage reads the full symbol.
It takes more (or less) fuel to ll up than the gage
reads. For example, the gage reads half full, but it
took more (or less) than half of the tank’s
capacity to t it.
The gage pointer may move while cornering,
braking or speeding up.
The gage may not indicate the tank is empty when
the ignition is turned off.
The gage reading may change slightly within the
rst several minutes after starting the vehicle.
SeeDIC Controls and Displays on page 3-48for more
information.

Driver Information Center (DIC)
The Driver Information Center (DIC) gives you the
status of many of your vehicle’s systems. It is also
used to display driver personalization features
and warning/status messages. The DIC display is
located on the instrument panel cluster below the
speedometer and tachometer, directly above the
steering column. The DIC buttons are located on the
instrument panel, to the right of the instrument
panel cluster.
The DIC comes on when the ignition is turned on.
After displaying CORVETTE BY CHEVROLET, the DIC
will display the current driver and the information that
was last displayed before the engine was turned off.
If a problem is detected, a warning message will appear
on the DIC display. Be sure to take any message that
appears on the display seriously and remember that
clearing the message will only make the message
disappear, not correct the problem.
