北米Model "A8130BE-B" EDITED: 2007/ 7/ 25
7-6 Starting and operating
State emission testing (U.S.
only)
WARNING
Testing of an All-Wheel Drive vehicle
must NEVER be performed on a
single two-wheel dynamometer. At-
tempting to do so will result in
uncontrolled vehicle movement and
may cause an accident or injuries to
persons nearby.
CAUTION
Resultant ve hicle 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.
At state inspection time, remember to
tell your inspection or service station in
advance not to place your SUBARU
AWD vehicle on a two-wheel dynam-
ometer. Otherwise, serious transmis-
sion damage will result.
Some states have started using dynam-
ometers in their state inspection programs
in order to meet their obligation under
federal law to implement stricter vehicle
emission standards to reduce air pollution
from cars. 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. Depending on the
severity of a state’s air pollution problems,
the states must adopt either a “basic” or
“enhanced” vehicle emission inspection
test. Normally, a portion of the basic
emission test consists of an emission
inspector inserting an analyzer probe into
the exhaust pipe of an idling vehicle for a
short period of time. States with more
severe air pollution problems are required
to adopt an enhanced vehicle emission
test. This test simulates actual driving
conditions on a dynamometer and permits
more accurate measurement of tailpipe
emitted pollution than the basic emission
test.
The U.S. Environmental Protection
Agency (EPA) and states using two-wheel
dynamometers in their emission testing
programs have EXEMPTED SUBARU
AWD vehicles from the portion of the
testing program that involves a two-wheel
dynamometer.
There are some states that use four-wheel
dynamometers in their testing programs.
When properly used, that equipment will
not damage an AWD SUBARU vehicle.
Under no circumstances should the rear
wheels be jacked off the ground, nor
should the driveshaft be disconnected for
state emission testing.
The EPA has issued regula tions for
inspecting the On-Board Diagnostic
(OBD) system as part of the state emis-
sions inspection. The OBD system is
designed to detect engine and transmis-
sion problems that might cause vehicle
emissions to exceed allowable limits.
These inspections apply to all 1996 model
year and newer passenger cars and light
trucks. Over 30 states plus the District of
Columbia have implemented the OBD
system inspection.
. The inspection of the OBD system
consists of a visual operational check of
the “CHECK ENGINE” warning light/
malfunction indicator lamp (MIL) and an
examination of the OBD system with an
electronic scan tool while the engine is
running
. Avehicle
passes the OBD system
inspection if proper the “CHECK EN-
GINE” warning light/MIL illumination is
observed, there is no stored diagnostic
trouble codes, and the OBD system
readiness monitors are complete.
