WARNING!
If unauthorized equipment is connected to
the OBD II connection port, such as a
driver-behavior tracking device, it may:
• Be possible that vehicle systems,
including safety related systems, could
be impaired or a loss of vehicle control
could occur that may result in an acci-
dent involving serious injury or death.
• Access, or allow others to access, infor-
mation stored in your vehicle systems,
including personal information.
EMISSIONS INSPECTION
AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement
to pass an inspection of your vehicle's emissions
control system. Failure to pass could prevent
vehicle registration.

For states that require an Inspection
and Maintenance (I/M), this check
verifies the Malfunction Indicator Light
(MIL) is functioning and is not on when
the engine is running, and that the OBD II system
is ready for testing.
Normally, the OBD II system will be ready. The
OBD II system may not be ready if your vehicle
was recently serviced, recently had a depleted
battery or a battery replacement. If the OBD II
system should be determined not ready for the
I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition actuated test,
which you can use prior to going to the test
station. To check if your vehicle's OBD II system is
ready, you must do the following:
1. Cycle the ignition switch to the ON position,
but do not crank or start the engine.
NOTE:
If you crank or start the engine, you will have to
start this test over.
2. As soon as you cycle the ignition switch to the
ON position, you will see the Malfunction Indi-
cator Light (MIL) symbol come on as part of a
normal bulb check.
3. Approximately 15 seconds later, one of two
things will happen:
• The MIL will flash for about 10 seconds
and then return to being fully illuminated
until you turn OFF the ignition or start the
engine. This means that your vehicle's
OBD II system is not ready and you should
not proceed to the I/M station.
• The MIL will not flash at all and will remain
fully illuminated until you place the ignition
in the off position or start the engine. This
means that your vehicle's OBD II system is
ready and you can proceed to the I/M
station.
If your OBD II system is not ready, you should see
an authorized dealer or repair facility. If your
vehicle was recently serviced or had a battery
failure or replacement, you may need to do
nothing more than drive your vehicle as you
normally would in order for your OBD II system to
update. A recheck with the above test routine
may then indicate that the system is now ready.
Regardless of whether your vehicle's OBD II
system is ready or not, if the MIL is illuminated
during normal vehicle operation you should have
your vehicle serviced before going to the I/M
station. The I/M station can fail your vehicle
because the MIL is on with the engine running.
