Emissions Inspection And Maintenance Programs - Alfa Romeo Giulia 2024 Owner's Manual

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 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 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
previously mentioned 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.
