Transmission - Ford 2013 Fusion Owner's Manual

These temporary malfunctions can be
corrected by filling the fuel tank with good
quality fuel, properly closing the fuel fill
inlet 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
stay off the next time the engine is started.
A driving cycle consists of a cold engine
startup followed by mixed city/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, the vehicle may need
to be serviced. See On-Board Diagnostics.
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, the vehicle is considered not ready
for I/M testing.
Fuel and Refueling
If the vehicle's engine or transmission has
just been serviced, or the battery has
recently run down or been replaced, the
OBD-II system may indicate that the
vehicle is not ready for I/M testing. To
determine if the vehicle is ready for I/M
testing, turn the ignition key to the on
position for 15 seconds without cranking
the engine. If the service engine soon
indicator blinks eight times, it means that
the vehicle is not ready for I/M testing; if
the service engine soon indicator stays on
solid, it means that the vehicle is ready for
I/M testing.
The OBD-II system is designed to check
the emission control system during normal
driving. A complete check may take several
days. If the vehicle is not ready for I/M
testing, the following driving cycle
consisting of mixed city and highway
driving may be performed:
15 minutes of steady driving on an
expressway/highway followed by 20
minutes of stop-and-go driving with at
least four 30-second idle periods.
Allow the vehicle to sit for at least eight
hours without starting the engine. Then,
start the engine and complete the above
driving cycle. The engine must warm up to
its normal operating temperature. Once
started, do not turn off the engine until the
above driving cycle is complete. If the
vehicle is still not ready for I/M testing, the
above driving cycle will have to be
repeated.
