obd LINCOLN MKX 2011 Owners Manual

Solid illumination after the engine is started indicates the on-board
diagnostics system (OBD-II) has detected a malfunction. Refer to
On-board diagnostics (OBD-II)in theMaintenance and Specifications
chapter. If the light is blinking, engine misfire is occurring which could
damage your catalytic converter. Drive in a moderate fashion (avoid
heavy acceleration and deceleration) and contact your authorized dealer
as soon as possible.
WARNING:Under engine misfire conditions, excessive exhaust
temperatures could damage the catalytic converter, the fuel
system, interior floor coverings or other vehicle components, possibly
causing a fire.
Powertrain malfunction/reduced
power (RTT):Illuminates when a
powertrain or an AWD fault has
been detected. Contact your
authorized dealer as soon as possible.
Brake system warning light:To
confirm the brake system warning
light is functional, it will
momentarily illuminate when the
ignition is turned to on when the
engine is not running, or in a position between on and start, or by
applying the parking brake when the ignition is turned to on. If the brake
system warning light does not illuminate at this time, contact your
authorized dealer as soon as possible. Illumination after releasing the
parking brake indicates low brake fluid level or a brake system
malfunction. Contact your authorized dealer as soon as possible.
WARNING:Driving a vehicle with the brake system warning
light on is dangerous. A significant decrease in braking
performance may occur. It will take you longer to stop the vehicle.
Contact your authorized dealer as soon as possible. Driving extended
distances with the parking brake engaged can cause brake failure and
the risk of personal injury.

If other than Ford, Motorcraftor Ford-authorized parts are used for
maintenance replacements or for service of components affecting
emission control, such non-Ford parts should be equivalent to genuine
Ford Motor Company parts in performance and durability.
WARNING:Do not park, idle, or drive your vehicle in dry grass
or other dry ground cover. The emission system heats up the
engine compartment and exhaust system, which can start a fire.
Illumination of the service engine soon
indicator, charging system
warning light or the temperature warning light, fluid leaks, strange odors,
smoke or loss of engine power could indicate that the emission control
system is not working properly.
An improperly operating or damaged exhaust system may allow exhaust
to enter the vehicle. Have a damaged or improperly operating exhaust
system inspected and repaired immediately.
WARNING:Exhaust leaks may result in entry of harmful and
potentially lethal fumes into the passenger compartment.
Do not make any unauthorized changes to your vehicle or engine. By
law, vehicle owners and anyone who manufactures, repairs, services,
sells, leases, trades vehicles, or supervises a fleet of vehicles are not
permitted to intentionally remove an emission control device or prevent
it from working. Information about your vehicle’s emission system is on
the Vehicle Emission Control Information Decal located on or near the
engine. This decal also lists engine displacement.
Please consult yourWarranty Guidefor complete emission warranty
information.
On-board diagnostics (OBD-II)
Your vehicle is equipped with a computer that monitors the engine’s
emission control system. This system is commonly known as the
on-board diagnostics system (OBD-II). The OBD-II system protects the
environment by ensuring that your vehicle continues to meet
government emission standards. The OBD-II system also assists your
authorized dealer in properly servicing your vehicle. 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 are:
1. The vehicle has run out of fuel—the engine may misfire or run poorly.
Maintenance and Specifications
319
2011 MKX(mkx)

2. Poor fuel quality or water in the fuel—the engine may misfire or run
poorly.
3. The fuel fill inlet may not have been properly closed. SeeEasy Fuel™
“no cap” fuel systemin this chapter.
4. Driving through deep water—the electrical system may be wet.
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. 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.
If the service engine soon
indicator is on or the bulb does not
work, the vehicle may need to be serviced. Refer toOn-board
diagnostics (OBD-II)in this chapter.
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.
POWER STEERING FLUID
Check the power steering fluid. Refer toscheduled maintenance
information.
1. Start the engine and let it run
until it reaches normal operating
temperature (the engine coolant
temperature gauge indicator will be
near the center of the normal area
between H and C).
2. While the engine idles, turn the
steering wheel left and right several
times.
3. Turn the engine off.
4. Check the fluid level in the reservoir. It should be between the MIN
and MAX lines. Do not add fluid if the level is in this range.
5. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the range between the MIN and MAX lines. Be
sure to put the cap back on the reservoir. Refer toMaintenance
product specifications and capacitiesin this chapter for the proper
fluid type.
