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 and/or provinces that require an Inspec-
tion 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 replace-
ment. 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 posi-
tion, you will see the "Malfunction Indicator 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 igni-
tion 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 illu-
minated 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 autho-
rized 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.
