a computer which monitors
operation of the fuel,
ignition and emission
control systems.

system
is
called OBD

(On-Board
Diagnostics-Second Generation) and is intended
to
assure that emissions are at acceptable levels for

of

environment.
(In
Canada,
OBD
I1
is replaced by
Enhanced Diagnostics.) The SERVICE ENGINE

be
indicated

may

system is also designed to assist your service technician
in correctly diagnosing any malfunction.
