2021 FORD F650/750 sensor

If your vehicle is rapidly approaching
another vehicle traveling in the same
direction as yours, the system provides two
levels of functionality:
1. Alert.
2. Active Braking.
Alert: When active, a flashing visual
warning appears and an audible warning
tone sounds.
Active Braking
: Active Braking is active
at speeds above approximately 14.9 mph
(24 km/h). Active braking may activate if
the system determines that a collision is
imminent. The system may help the driver
reduce impact damage or avoid the crash
completely.
Pre-Collision Assist Settings
Active braking turns on every time you
switch the ignition on. You cannot adjust
the Pre-Collision Assist settings.
Note: We recommend that you switch the
system off if you install a snow plow or
similar object in such a way that it may
block the radar sensor. Your vehicle
remembers the system status across key
cycles. Blocked Sensors
Radar sensor.
1
The information display shows a blocked
sensor message to indicate a sensor
obstruction. The radar sensor is located
behind the bumper and mounted to the
frame below the center of the grille. If you
install a snow plow or similar object, you
may block the radar sensor. With a blocked
sensor, the Pre-Collision Assist system
may not function, or performance may
reduce. The following table lists possible
causes and actions for when this message
displays.

Radar Troubleshooting
Action
Cause
Clean the grille surface in front of the radaror remove the object causing the obstruc- tion.
The surface of the radar in the grille is dirty
or obstructed in some way.
Wait a short time. It may take several
minutes for the radar to detect that there is no obstruction.
The surface of the radar in the grille is clean
but the message remains in the display screen.
The Pre-Collision Assist system is tempor-
arily disabled. Pre-Collision Assist automat-ically reactivates a short time after the weather conditions improve.
Heavy rain, spray, snow or fog is interfering
with the radar signals.

arily disabled. Pre-Collision Assist automat-ically reactivates a short time after the weather conditions improve.
Swirling water or snow or ice on the surface
of the road may interfere with the radar signals.
Contact an authorized dealer to have theradar checked for proper coverage and operation.
Radar is out of alignment due to a front end
impact.
Note: If something hits the front end of your
vehicle or damage occurs and your vehicle
has a radar sensor, the radar sensing zone
may change. This could cause missed or
false vehicle detections. Contact an
authorized dealer to have the radar checked
for proper coverage and operation. PRE-COLLISION ASSIST -

BRAKES WARNING: You are responsible for
controlling your vehicle at all times. The
system is designed to be an aid and does
not relieve you of your responsibility to
drive with due care and attention. Failure
to follow this instruction could result in
the loss of control of your vehicle,
personal injury or death.

We recommend that you switch the
system off if you install a snow plow or
similar object in such a way that it may
block the radar sensor. Your vehicle
remembers the selected setting across key
cycles.

2 If a message regarding a blocked sensor
or camera appears in the information
display, the radar signals or camera images
are obstructed. With a blocked sensor or
camera, the Pre-Collision Assist system
may not function, or performance may
reduce. The following table lists possible
causes and actions for when this message
displays.
Camera Troubleshooting Action
Cause
Clean the outside of the windshield in frontof the camera.
The windshield in front of the camera is
dirty or obstructed in some way.
Wait a short time. It may take several
minutes for the camera to detect that there is no obstruction.

Radar is out of alignment due to a front end
impact.
Note: Proper system operation requires a
clear view of the road by the camera. Have
any windshield damage in the area of the
camera's field of view repaired.
Note: If something hits the front end of your
vehicle or damage occurs and your vehicle
has a radar sensor, the radar sensing zone
may change. This could cause missed or
false vehicle detections. Contact an
authorized dealer to have the radar checked
for proper coverage and operation.
Note: If your vehicle detects excessive heat
at the camera or a potential misalignment
condition, a message may display in the
information display indicating temporary
sensor unavailability. When operational
conditions are correct, the message
deactivates. For example, when the ambient
temperature around the sensor decreases
or the sensor automatically recalibrates
successfully.

After installation of the new filter element,
reset the gauge by pressing the reset
button on top of the gauge.
We recommend the following actions after
operating the vehicle up to 200 mi
(320 km) in heavy snowfall or extreme
rain:
• Snow: At the earliest opportunity, open
the hood and clear all the snow and ice
from the air filter housing inlet. Do NOT
remove the foam filter and reset the
air filter restriction gauge.
• Extreme rain: The air filter dries after
about 15– 30 minutes at highway
speeds. At the earliest opportunity,
open the hood and reset the air filter
restriction gauge.
Air Filter Replacement
When replacing the air filter element, use
a Motorcraft® air filter element. See
Motorcraft Parts
(page 283).
Note: Failure to use the correct air filter
element may result in severe engine
damage. 1. Locate the mass airflow sensor
electrical connector on the air inlet
tube. Disconnect the electrical
connector. Unlock the locking clip on
the connector, then squeeze and pull
the connector off the air inlet tube. 222
F650750 (TBC) , enUSA, Edition date: 202010, Second-Printing MaintenanceE163373 E317651 x3E317652

2. Remove the clips that secure the air
filter housing cover. Push the air filter
cover forward and away from you when
pulling up slightly to release it.
3. Remove the air filter element from the
air filter housing. 4. Remove and install a new foam filter,
if needed. See Scheduled
Maintenance (page 319). If you do not
replace the foam filter, be sure the
existing foam filter is in place. 5.
Install a new air filter element. Be sure
that the groove seal on the pleated
paper filter traps both sides of the
vertical partition of the air box. 6. Engage the clips to secure the air filter
housing cover to the air filter housing.
Be careful not to crimp the filter
element edges between the air filter
housing and cover. Ensure that you
align the tabs on the edge properly into
the slots.
7. Reconnect the mass airflow sensor electrical connector to the inlet tube.
Make sure the locking tab on the
connector is in the locked position.
CHANGING THE ENGINE AIR
FILTER - 7.3L WARNING:
To reduce the risk of
vehicle damage and personal burn
injuries, do not start your engine with the
air cleaner removed and do not remove
it while the engine is running.
Note: Operating your vehicle in heavy
snowfall or extreme rain conditions may
allow excessive amounts of snow or water
into the air intake system. This could plug
or soak the air filter, and cause the engine
to lose power or shut down.
When replacing the air filter element, use
a Motorcraft® air filter element. See
Motorcraft Parts
(page 283).
Note: Failure to use the correct air filter
element may result in severe engine
damage, and may void the vehicle warranty.
Change the air filter element at the correct
interval. See
Scheduled Maintenance
(page 319).
