Emissions Inspection and Maintenance Programs Some state/provincial and local governments have or may begin programs to inspect the emission control equipment on your vehicle. Failure to pass this inspection could prevent you from getting a vehicle registration. Here are some things you need to know to help your vehicle pass an inspection: Your vehicle will not pass this inspection if the SERVICE ENGINE SOON or CHECK ENGINE light is on or not working properly. Your vehicle will not pass this inspection if the OBD (on-board diagnostic) system determines that critical emission control systems have not been completely diagnosed by the system. The vehicle would be considered not ready for inspection. This can happen if you have recently replaced your battery or if your battery has run down. The diagnostic system is designed to evaluate critical emission control systems during normal driving. This may take several days of routine driving. If you have done this and your vehicle still does not pass the inspection for lack of OBD system readiness, see your dealer or qualified service center to prepare the vehicle for inspection. 3-46

Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments
have or
may begin programs to inspect the emission control
equipment
on
your vehicle. Failure to pass this
inspection could prevent you from getting a vehicle
registration.
Here are some things you
need to know to help your
vehicle pass
an inspection:
Your vehicle will not
pass this inspection
if
the
SERVICE
ENGINE
SOON
or CHECK
ENGINE light is on
or not
working properly.
Your vehicle will not pass this inspection
if
the
OBD
(on-board diagnostic) system determines that
critical
emission control systems
have not been
completely
diagnosed by the system.
The vehicle would
be
considered not ready for inspection. This can
happen
if
you
have recently replaced your
battery or
if
your
battery has
run
down.
The diagnostic system
is
designed to evaluate critical emission control systems
during normal driving. This may take several
days
of routine driving. If
you
have
done this and
your
vehicle
still does
not
pass the inspection for
lack of
OBD
system readiness, see
your dealer or qualified
service
center to prepare the vehicle
for
inspection.
