1996 CHEVROLET CORVETTE Owners Manual

Downloaded from www.Manualslib.com manuals search engine Malfunction Indicator Lamp (Service Engine Soon Light)
Your Corvette is equipped
with a.computer which
SERVICE
SOON
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD I1 (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. (In Canada, OBD I1 is replaced by
Enhanced Diagnostics.) The SERVICE ENGINE
SOON
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, which
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 won’t
work as well, your fuel economy won’t 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.
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 doesn’t come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:
0
0 Light Flashing -- A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service is required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.

The following may prevent more serious damage to
your vehicle:
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you just put fuel into your vehicle?
If
so, reinstall the fuel cap, making sure to fully install
the cap. The diagnostic system can determine if the fuel
cap has been left
off or improperly installed. This will
allow fuel to evaporate into the atmosphere.
A few
driving trips 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.
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure to install the fuel cap properly. It
will take a few driving trips to turn the light
off.
Reduce vehicle speed.
Avoid hard accelerations.
0 Avoid steep uphill grades.
If the light stops flashing and remains
on steady see “If
the Light Is On Steady” following.
If
the light continues to flash, when it is safe to do so,
stop the vehicle. Put your vehicle in PARK (P). 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 flashing follow the
previous steps, and drive the vehicle to your dealer or
qualified service center for service.

Downloaded from www.Manualslib.com manuals search engine Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index). 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, misfiring, 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 this condition, 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,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.
Low Oil Light
LOW
OIL
This light should come on
while you are starting your
engine.
If the light doesn’t
come on, have it repaired. If
the light comes on while
starting your engine and
stays on, your engine oil
level may be too low.
You
may need to add oil. See
“Engine Oil” in the Index.

0
WA
OIL
PRESS
PSI
The engine oil pressure
gauge 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 Wa).
(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. See “Engine Oil”
in the Index.
A CAUTIOh:
Don’t keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.

NOTICE:
Damage to your engine from neglected oil
problems can be costly and

OIL TEMP OF
This gauge shows your
engine oil temperature. Oil
temperature may vary with
the type
of driving you do
and weather conditions.
If your gauge pointer moves close to or into the shaded
area and stays there, your oil temperature is too high.
Check the engine coolant temperature and engine oil
level.
If your engine is too hot, see “Engine
Overheating” in the Index. Your vehicle may need
service; see your dealer.

For numeric gauge
measurements, press the GAUGES button on the trip
monitor until
OIL appears.
The number that appears next to the fuel gauge is the oil
temperature.
If LO appears, the temperature is below
32°F (OOC).

CHANGE
OIL
The CHANGE OIL light
comes on for a few seconds
when you turn the ignition
on. It will come on and stay
on when it’s time to change
your oil.
The monitor uses oil temperature and engine revolutions
to decide when the oil
is nearly worn out. The light is
only a reminder, though. Be sure
to reset the monitor when your oil
is changed,
even
if the CHANGE OIL light didn’t come on. If you
don’t reset the monitor, it won’t work correctly. Follow
these steps:
1. Turn the key to RUN, but don’t start the engine.
2. Press ENG MET on the trip monitor. Then, within
five seconds, press it again.
3. Within five seconds, press and hold GAUGES on the
trip monitor. The CHANGE OIL light should flash.
4. Hold the GAUGES button until the CHANGE OIL
light stops flashing and goes out. This should take
about
10 seconds.
When the light goes out, the monitor is reset. If
the monitor doesn’t reset, turn the ignition off, then
try again.

SERVICE RIDE
CONTROL
If your vehicle is equipped
with Ride Control, this light
should come on for a few
seconds when you start
your vehicle.
If the light stays on or comes on while you’re driving,
there may be a problem with your Ride Control system.
You can still drive, but you should see your dealer soon.
The SERVICE RIDE CONTROL light may also come
on if the selective ride control
knob is not placed fully
into a position. For example, if the selection position is
between TOUR and SPORT
or SPORT and PERF, the
light may come on. If the light comes on for
this reason,
move the select switch
to the desired position and the
light should go out.
Passive Keyless Entry Light
