7-2. State Emission Testing
(U.S. Only)
WARNING
Only use a four-wheel dynamometer
when testing an All-Wheel Drive
(AWD) model.
Testing of an AWD model must
NEVER be performed on a single
two-wheel dynamometer. Attempt-
ing to do so will result in uncon-
trolled vehicle movement and may
cause an accident or injuries to
persons nearby.
CAUTION
. At state inspection time, remem-
ber to tell your inspection or
service station in advance not to
place your SUBARU AWD vehicle
on a two-wheel dynamometer.
Otherwise, serious transmission
damage will result.
. Resultant vehicle damage due to
improper testing is not covered
under the SUBARU Limited War-
ranty and is the responsibility of
the state inspection program or
its contractors or licensees.
California and a number of federal states
have Inspection/Maintenance programs to
inspect your vehicle’s emission control
system. If your vehicle does not pass this
test, some states may deny renewal of
your vehicle’s registration.
Your vehicle is equipped with a computer
that monitors the performance of the
engine’s emission control system. Certi-
fied emission inspectors will inspect the
On-Board Diagnostic (OBDII) system as
part of the state emission inspection
process. The OBDII system is designed
to detect engine and transmission pro-
blems that might cause the vehicle emis-
sions to exceed allowable limits. OBDII
inspections apply to all 1996 model year
and newer passenger cars and trucks.
Over 30 states plus the District of Colum-
bia have implemented emission inspection
of the OBDII system.
. The inspection of the OBDII system
consists of a visual operational check of
the “
CHECK ENGINE ” warning light/mal-
function indicator light (MIL) and an ex-
amination of the OBDII system with an
electronic scan tool.
. A vehicle passes the OBDII system
inspection if proper operation of the
“
CHECK ENGINE ” warning light is ob-
served, there are no stored diagnostic
trouble codes, and the OBDII readiness
monitors are all complete.
.
A vehicle fails the OBDII inspection if
the “ CHECK ENGINE ” warning light is not
properly operating (light is illuminated or is
not working due to a burned out bulb) or
there is one or more diagnostic trouble
codes stored in the vehicle’s computer.
. A state emission inspection may reject
(not pass or fail) a vehicle if the number of
OBDII system readiness monitors “
NOT
READY ” is greater than one. If the
vehicle’s battery has been recently re-
placed or disconnected, the OBDII system
inspection may indicate that the vehicle is
not ready for the emission test. Under this
condition, the vehicle driver should be
instructed to drive his/her vehicle for a
few days to reset the readiness monitors
and return for an emission re-inspection.
. Owners of rejected or failing vehicles
should contact their SUBARU Dealer for
service.
Some states still use dynamometers in
their emission inspection program. A
dynamometer is a treadmill or roller-like
testing device that allows your vehicle’s
wheels to turn while the vehicle remains in
one place. Prior to your vehicle being put
on a dynamometer, tell your emission
