Fiat 124 SPIDER ABARTH 2017 User Manual page 72

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 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.
