FORD 2015 Transit v.2 - Manual (Page 126)

When the service engine soon
indicator illuminates, the OBD-II
system has detected a
malfunction. Temporary malfunctions may
cause the service engine soon indicator to
illuminate.
Examples of temporary malfunctions are:
•
The vehicle has run out of fuel.
• Poor fuel quality or water in the fuel.
• The engine may misfire or run rough.
• The fuel filler door may not have been
closed correctly. See Refueling (page
118).
• Driving through deep water. The
electrical system may be wet.
You can correct these temporary
malfunctions by filling the fuel tank with
good quality fuel, correctly closing the fuel
filler door or letting the electrical system
dry out. After three driving cycles without
these or any other temporary malfunctions
present, the service engine soon indicator
should not illuminate. A driving cycle
consists of a cold engine startup followed
by mixed city or highway driving. No
additional vehicle service is required.
If the service engine soon indicator remains
on, have your vehicle serviced at the first
available opportunity. Although some
malfunctions detected by the OBD-II may
not have symptoms that are apparent,
continued driving with the service engine
soon indicator on can result in increased
emissions, lower fuel economy, reduced
engine and transmission smoothness, and
lead to more costly repairs.
Readiness for
Inspection/Maintenance (I/M)
Testing
Some state/provincial and local
governments may have
Inspection/Maintenance (I/M) programs
to inspect the emission control equipment
on your vehicle. Failure to pass this
inspection could prevent you from getting
a vehicle registration.
If the service engine soon
indicator is on or the bulb does
not work, you may need to have
your vehicle serviced. See On-Board
Diagnostics (OBD-II).
Your vehicle may not pass the I/M test if
the service engine soon indicator is on or
not working properly (bulb is burned out),
or if the OBD-II system has determined
that some of the emission control systems
have not been properly checked. In this
case, your vehicle is not ready for I/M
testing.
If the vehicle engine or transmission has
just been serviced or the battery has
recently run out of charge or been
replaced, the OBD-II system may indicate
that your vehicle is not ready for I/M
testing. To determine if the vehicle is ready
for I/M testing, switch the ignition on for 15
seconds without cranking the engine. If the
service engine soon indicator flashes on
and off eight times, it means that your
vehicle is not ready for I/M testing; if the
service engine soon indicator illuminates
and remains on, it means that your vehicle
is ready for I/M testing.
The OBD-II system monitors the emission
control system during normal driving. A
complete check may take several days.
