Malfunction Indicator Lamp

(Service Engine Soon Light)
This system is called OBD II (On
-
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.
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
