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 Mainte-
nance (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 dead 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 key-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. Insert your ignition key into the ignition switch.

2. Turn the ignition to the ON position, but do not crank
or start the engine.

3. If you crank or start the engine, you will have to start
this test over.

4. As soon as you turn your key to the ON position, you
will see the MIL symbol come on as part of a normal bulb
check.
