Malfunction Indicator

Light)
SERVICE
ENGINE
SOON
Your Cadillac 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 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 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:
Light FIashing
--
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.
