2020 FORD F-550 ignition

Possible Cause and Resolution
Symptom
I cannot see SYNC when I
search for Wi-Fi networks on
my cell phone or other
device. –
System limitation.
•SYNC does not provide a Wi-Fi hotspot at this time.
– Weak network signal
•Move your vehicle closer to the Wi-Fi hotspot or to
a place where the network signal is not obstructed.
– Wi-Fi hotspot in high demand or has a slow Internet
connection.
•Use a more reliable Wi-Fi hotspot.
Software downloads take
too long.
–No software update available.
– Wi-Fi network requires a subscription or acceptance
of terms and conditions.
•Test the connection using another device. If the
network requires a subscription or acceptance of
terms and conditions, contact the network service
provider.
The system seems to
connect to a Wi-Fi network
and the signal strength is
excellent but the software
does not update.
Personal Profiles (If Equipped) Possible Cause and Solution
Symptom
You have not set up Personal Profiles.
I cannot create a profile. You entered an invalid profile.
You did not select a memory button when prompted.
You did not have the ignition on or in park (P), or you
shifted out park (P) when creating a profile.
Personal Profiles has been switched off.
You did not select the lock button on the remote control.
I cannot link a remote
control. The remote control selected was already associated with
another profile and the system declined to overwrite.
The system performed a profile recall when linking a
remote control.
You did not have the ignition on or in park (P), or you
shifted out park (P) when creating a profile.

AUXILIARY SWITCHES
For maximum vehicle performance, keep
the following information in mind when
adding accessories or equipment to your
vehicle:
•
When adding accessories, equipment,
passengers and luggage to your
vehicle, do not exceed the total weight
capacity of the vehicle or of the front
or rear axle (GVWR or GAWR as
indicated on the Safety Compliance
Certification label). Ask an authorized
dealer for specific weight information.
• The Federal Communications
Commission (FCC) and Canadian
Radio Telecommunications
Commission (CRTC) regulate the use
of mobile communications systems
equipped with radio transmitters, for
example, two-way radios, telephones
and theft alarms. Any such equipment
installed in your vehicle should comply
with Federal Communications
Commission (FCC) and Canadian
Radio Telecommunications
Commission (CRTC) regulations, and
should be installed by an authorized
dealer.
• An authorized dealer needs to install
mobile communications systems.
Improper installation may harm the
operation of your vehicle, particularly
if the manufacturer did not design the
mobile communication system
specifically for automotive use.
• If you or an authorized Ford dealer add
any non-Ford electrical or electronic
accessories or components to your
vehicle, you may adversely affect
battery performance and durability. In
addition, you may also adversely affect
the performance of other electrical
systems in the vehicle. The auxiliary switch option package
provides six switches mounted in the
overhead console. These switches operate
when the vehicle is running or from battery
power, depending on the switchable fuse
AUXF4's location in the upfitter relay box.
We recommend, however, that the engine
remain running to maintain battery charge
when using the auxiliary switches for
extended periods of time or higher current
draws.
Note:
When your vehicle has a diesel
engine, use the auxiliary switches only when
the engine is running. The glow plugs also
drain battery power when the ignition key is
in the on position. Using the auxiliary
switches, even for limited amounts of time,
can cause your battery to drain quickly and
prevent your vehicle from restarting.
When switched on, the auxiliary switches
provide electrical battery power for a
variety of personal or commercial uses.
Switches 1 through 4 provide 25 amps.
Switches 5 and 6 provide 40 amps.
The relay box for the auxiliary switches is
in the engine compartment. See your
authorized dealer for service.
