2022 FORD F-150 trailer brake system fault

Note:
If your vehicle sustains damage to
the bumper or fascia leaving it misaligned
or bent, it could alter the sensing zone
causing inaccurate measurement of
obstacles or false alerts.
Note: Vehicle loading and suspension
changes can impact the angle of the sensors
and may change the normal detection zone
of the system resulting in inaccurate
measurement of obstacles or false alerts.
Note: When you connect a trailer, the
system may detect the trailer and provide
an alert, or the system turns off. If the
system does not turn off, switch the system
off manually after you connect the trailer.
Note: You may experience reduced system
performance on road surfaces that limit
deceleration. For example, roads with ice,
loose gravel, mud or sand.

FREQUENTLY ASKED QUESTIONS
Why is reverse braking assist unavailable?
•
Make sure the reverse braking assist is
on. See Switching Reverse Braking
Assist On and Off (page 293).
• Make sure that all doors and the
liftgate or tailgate are closed. Drive the
vehicle on a straight road for a short
period. If the message remains, contact
an authorized dealer.
• Make sure the cross traffic alert system
is on if equipped.
See Switching
Reverse Braking Assist On and Off
(page
293).
• Make sure the rear parking aid system
is on. See Rear Parking Aid
(page 314).
• Make sure the traction control is on.
See

Note: The traction control automatically
turns off if four-wheel drive low and certain
drive modes such as mud/ruts and
snow/sand is activated.
• The vehicle may have sustained a rear
end impact. Contact an authorized
dealer to have the sensors checked for
proper coverage and operation.
• An anti-lock brake, traction control or
stability control event may have
occurred. Reverse braking assist
resumes operation when the event is
complete.
• Make sure the rear view camera and
360 degree camera are not dirty or
obstructed. If dirty, clean the camera.
If the message still appears after
cleaning the camera, wait a short time
for the message to clear. If the
message does not clear, contact an
authorized dealer. •
Make sure the cross traffic alert and
rear parking aid sensors are not
blocked or faulty.
See Locating the
Cross Traffic Alert Sensors (page
373). See Locating the Rear Parking
Aid Sensors
(page 314).
• You recently had your vehicle serviced,
or the battery disconnected. Drive your
vehicle a short distance to resume
system operation.
• Reverse braking assist does not
function when you connect a trailer.
Operation resumes when you
disconnect the trailer.
Note: If the answers to why the system is

CONNECTING A TRAILER
PRECAUTIONS
Do not tow a trailer until you drive your
vehicle at least 1,000 mi (1,600 km).
Consult your local motor vehicle laws for
towing a trailer.
See the instructions included with towing
accessories for the proper installation and
adjustment specifications.
Service your vehicle more frequently if you
tow a trailer. See
Normal Scheduled
Maintenance (page 645).
If you use a rental trailer, follow the
instructions the rental agency gives you.
When attaching the trailer wiring connector
to your vehicle, only use a proper fitting
connector that works with the vehicle and
trailer functions.
Account for the trailer coupler weight as
part of your vehicle load when calculating
the total vehicle weight.
Do not exceed the load limits. See
Calculating the Load Limit
(page 391).
HITCHES
HOOKING UP A TRAILER USING A
WEIGHT-DISTRIBUTING HITCH WARNING: Do not adjust the spring
bars so that your vehicle's rear bumper
is higher than before attaching the trailer.
Doing so will defeat the function of the
weight-distributing hitch, which may
cause unpredictable handling, and could
result in serious personal injury.
A weight-distributing hitch helps distribute
tongue load to all towing vehicle and trailer
wheels. For more information, visit the links

Note: If your vehicle does not recognize the
trailer, press and hold the brake pedal for a
few seconds.
Note: Trailer profiles store trailer types,
dimensions, preferences, trailer specific
mileage and fuel economy.
Note: Disabling the trailer detection
