Malfunction Indicator Lamp

Check Engine Light
Canada
This system is called OBD II (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 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.
Your vehicle has a
computer which
monitors operation
of the fuel, ignition,
and emission
control systems.
