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. 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.
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.
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:
