Alfa Romeo 4C SPIDER 2018, Owner'S Manual

Page: 89 / 294

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 ten 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 your
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replace-
ment, 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 ser-
viced before going to the I/M station. The I/M station
can fail your vehicle because the MIL is on with the
engine running.
