1997 Oldsmobile Achieva check engine light

During normal operation, the SECURITY light will go
off after the engine is started. If the engine stalls and the
SECURITY light flashes, wait until the light stops
flashing before trying to restart the engine. Remember to
release the key from the
START position as soon as the
engine starts.
If you are driving and the SECURITY
light comes on, you
will be able to restart the engine if
you turn the engine off. However, your Passlock system
is not working properly and must be serviced by your
retailer. Your vehicle is not protected by Passlock at this
time. You may also want
to check the fuse (see “Fuses
and Circuit Breakers” in the Index). See your
Oldsmobile retailer for service.
If the SECURITY light comes on while the engine is
running, a problem has been detected and the system
may need service. See your dealer for service.
In an emergency, call the Oldsmobile Roadside
Assistance Program
at 1 -800-442-OLDS (6537).
New Vehicle cCBreak-InSS
NOTICE:
Your modern Oldsmobile doesn’t need an
elaborate “break-in.” But it will perform better
in the long run
if you follow these guidelines:
Don’t drive at any one speed -- fast or
slow
-- for the first 500 miles (805 km).
Don’t make full-throttle starts.
200 miles (322 km) or so. During this time
your new brake linings aren’t yet broken
in. Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking-in guideline every time you get new brake linings.
See “Towing
a Trailer” in the Index for
more information.
0 Avoid making hard stops for the first
Don’t tow a trailer during break-in.

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 briefly when you start the
engine just to let you know they’re 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’s
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’re
a big help.

Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for about eight seconds to remind people to
fasten their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light will
also come on and stay
on for about
20 seconds,
then it will flash for about
55 seconds. If the driver’s
belt is already buckled,
neither the chime nor the
light will come on.
Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows
AIR BAG. The system checks the
air bag’s electrical system for malfunctions. The light
tells you if there is an electrical problem. The system
check includes the
air. bag sensor, the air bag modules, the wiring and the
crash sensing and diagnostic module.
For more information on the air bag system, see “Air
Bag” in the Index.
This light will come on
when you
start your engine,
and it will flash for a few
seconds. Then the light
should
go out. This means
the system is ready. AIR
BAG
If the air bag readiness light stays on after you start the
engine or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to RUN.
If the
light doesn’t come on then, have it fixed
so it will be
ready to warn you
if there is a problem.

Charging System Indicator Light
The charging system indicator light will come on
when you start the engine,
then it should go out.
+I
If it stays on, or comes on while you are driving, 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.
Brake System Warning Light
Your Oldsmobile’s hydraulic brake system is divided
into two parts.
If one part isn’t working, the other part
can still work and stop
you. For good braking, though,
you need both parts working well.
If
the warning light comes on, there could be a brake
problem or the brake fluid level could be low. Have your
brake system inspected right away.

soon as you can.
Malfunction Indicator Lamp
(Check Engine
Light)
CHECK
ENGINE
Your Oldsmobile is
equipped with a computer
which 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 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.
2-64

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.
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. Retailer or qualified service center diagnosis
and service is required.
Light On Steady -- An emission control system
malfunction has been detected
on your vehicle.
Retailer or qualified service center diagnosis and
service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
0 Reducing vehicle speed.
0 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 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. 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 flashing,
follow the previous steps, and drive the vehicle
to your
retailer or qualified service center
for service.

If the Lipht Is On Steady
YOU may be ame 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. 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 (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 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,
have your retailer or qualified service center check the
vehicle. Your retailer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.

Oil Pressure Warning Light
This light tells you if there
could be a problem with
your engine oil pressure.
This light can come on briefly, which is normal and
doesn’t show a problem:
0 As a bulb check, the light comes on when you turn
your key
to RUN and goes off when the engine is
started. If it doesn’t, be sure to have it fixed so it will
be there
to warn you.
For the four cylinder engine, when idling at a stop
sign, the light may blink on and then off. In addition,
if you make
a hard stop, the light may come on for
a moment.
But, when this light comes on and stays on, it means oil
isn’t going through your engine properly.
You could be
low on oil, or you might have some other oil problem.
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
is not covered by
your warranty.
