2021 FORD E-450 ECU

PRINCIPLE OF OPERATION
WARNING: Airbags do not inflate
slowly or gently, and the risk of injury
from a deploying airbag is the greatest
close to the trim covering the airbag
module. WARNING:
All occupants of your
vehicle, including the driver, should
always properly wear their seatbelts,
even when an airbag supplemental
restraint system is provided. Failure to
properly wear your seatbelt could
seriously increase the risk of injury or
death. WARNING:
Properly secure
children 12 years old and under in a rear
seating position whenever possible. If
you are unable to properly secure all
children in a rear seating position,
properly secure the largest child on the
front seat. If you must use a forward
facing child restraint on the front seat,
move the seat as far back as possible.
Failure to follow these instructions could
result in personal injury or death. WARNING:
Do not place your arms
on the airbag cover or through the
steering wheel. Failure to follow this
instruction could result in personal injury. WARNING:
Do not place a
rearward facing child restraint in front of
an active airbag. Failure to follow this
instruction could result in personal injury
or death. WARNING:
Do not attempt to
service, repair, or modify the
supplementary restraint system or
associated components. Failure to
follow this instruction could result in
personal injury or death. WARNING:
Several airbag system
components get hot after inflation. To
reduce the risk of injury, do not touch
them after inflation. WARNING:
If a supplementary
restraint system component has
deployed, it will not function again. Have
the system and associated components
inspected as soon as possible. Failure to
follow this instruction could result in
personal injury or death.
The airbags are a supplemental restraint
system and are designed to work with the
seatbelts to help protect the driver and
right front passenger from certain upper
body injuries. Airbags do not inflate slowly;
there is a risk of injury from a deploying
airbag.
Note: You will hear a loud bang and see a
cloud of harmless powdery residue if an
airbag deploys. This is normal.
The airbags inflate and deflate rapidly
upon activation. After airbag deployment,
it is normal to notice a smoke-like, powdery
residue or smell the burnt propellant. This
may consist of cornstarch, talcum powder
(to lubricate the bag) or sodium
compounds (for example, baking soda)
that result from the combustion process
that inflates the airbag. Small amounts of
sodium hydroxide may be present which
may irritate the skin and eyes, but none of
the residue is toxic.
While the system is designed to help
reduce serious injuries, contact with a
deploying airbag may also cause abrasions
or swelling. Temporary hearing loss is also
a possibility as a result of the noise
associated with a deploying airbag.
Because airbags must inflate rapidly and
with considerable force, there is the risk of
death or serious injuries such as fractures,
facial and eye injuries or internal injuries,

PASSIVE ANTI-THEFT
SYSTEM
Note:
The system is not compatible with
non-Ford aftermarket remote start systems.
Use of these systems may result in vehicle
starting problems and a loss of security
protection.
Note: Metallic objects, electronic devices
or a second coded key on the same key
chain may cause vehicle starting problems
if they are too close to the key when starting
the engine. Prevent these objects from
touching the coded key while starting the
engine. Switch the ignition off, move all
objects on the key chain away from the
coded key and restart the engine if a
problem occurs.
Note: Do not leave a duplicate coded key
in the vehicle. Always take your keys and
lock all doors when leaving the vehicle.
SecuriLock®
The system is an engine immobilization
system designed to prevent someone from
starting the engine unless they use a
correctly coded key for your vehicle. Using
an incorrectly coded key may prevent the
engine from starting. A message may
appear in the information display. If you
are unable to start the engine with a
correctly coded key, a malfunction has
happened and a message may appear in
the information display.
Automatic Arming
The engine immobilization system arms
immediately after you switch the ignition
off.
Automatic Disarming
Switching the ignition on with a correctly
coded key disarms the engine
immobilization system. Replacement Keys
If your keys become lost or stolen and you
do not have a spare correctly coded key,
you need to have your vehicle towed to an
authorized dealer. You need to erase the
coded keys from your vehicle and program
new coded keys.
Store an extra correctly coded key away
from the vehicle in a safe place to help
prevent any inconveniences. See an
authorized dealer to purchase additional
spare or replacement keys.
Note:
Your vehicle comes with two
integrated keyhead transmitters.
Programming a Spare Integrated
Keyhead Transmitter
You can program your own integrated
keyhead transmitter or standard
SecuriLock coded keys to your vehicle.
This procedure programs both the engine
immobilizer keycode and the remote entry
portion of the remote control to your
vehicle
Only use integrated keyhead transmitters
or standard SecuriLock keys.
You must have two previously
programmed correctly coded keys and the
new unprogrammed key readily accessible.
See an authorized dealer to have the spare
key programmed if two previously
programmed correctly coded keys are not
available.
Read and understand the entire procedure
before you begin.
1. Insert the first previously programmed
correctly coded key into the ignition.
2. Switch the ignition from off to on. Keep
the ignition on for at least three
seconds, but no more than 10 seconds.
3. Switch the ignition off and remove the
first correctly coded key from the
ignition.

4. After three seconds but within 10
seconds of switching the ignition off,
insert the second previously correctly
coded key into the ignition.
5. Switch the ignition from off to on. Keep
the ignition on for at least three
seconds, but no more than 10 seconds.
6. Switch the ignition off and remove the
second previously programmed
correctly coded key from the ignition.
7. After three seconds but within 10 seconds of switching the ignition off
and removing the previously
programmed correctly coded key,
insert the new unprogrammed key into
the ignition.
8. Switch the ignition from off to on. Keep
the ignition on for at least six seconds.
9. Remove the newly programmed correctly coded key from the ignition.
If you successfully program the key, it
starts the engine and operates the remote
entry system, if the new key is an
integrated keyhead transmitter.
If you did not successfully program the key,
wait 10 seconds and repeat Steps 1 through
8. If you are still unsuccessful, take your
vehicle to an authorized dealer.
Note: You can program a maximum of
eight coded keys to your vehicle. All eight
can be integrated keyhead transmitters.

Hitches
Do not use a hitch that either clamps onto
the bumper or attaches to the axle. You
must distribute the load in your trailer so
that 10-15% of the total weight of the
trailer is on the tongue.
Weight-distributing Hitches
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.
When hooking-up a trailer using a
weight-distributing hitch, always use the
following procedure:
1. Park the loaded vehicle, without the trailer, on a level surface.
2. Measure the height to the top of your vehicle's front wheel opening on the
fender. This is H1.
3. Attach the loaded trailer to your vehicle
without the weight-distributing bars
connected.
4. Measure the height to the top of your vehicle's front wheel opening on the
fender a second time. This is H2.
5. Install and adjust the tension in the weight-distributing bars so that the
height of your vehicle's front wheel
opening on the fender is approximately
half the way down from H2, toward H1.
6. Check that the trailer is level or slightly
nose down toward your vehicle. If not,
adjust the ball height accordingly and
repeat Steps 2-6. When the trailer is level or slightly nose
down toward the vehicle:
•
Lock the bar tension adjuster in place.
• Check that the trailer tongue securely
attaches and locks onto the hitch.
• Install safety chains, lighting, and trailer
brake controls as required by law or the
trailer manufacturer.
Safety Chains
Note: Do not attach safety chains to the
bumper.
Always connect the safety chains to the
frame or hook retainers of your vehicle
hitch.
To connect the safety chains, cross the
chains under the trailer tongue and allow
enough slack for turning tight corners. Do
not allow the chains to drag on the ground.
Trailer Brakes WARNING: Do not connect a
trailer's hydraulic brake system directly
to your vehicle's brake system. Your
vehicle may not have enough braking
power and your chances of having a
collision greatly increase.
Electric brakes and manual, automatic or
surge-type trailer brakes are safe if you
install them properly and adjust them to
the manufacturer's specifications. The
trailer brakes must meet local and federal
regulations.
The rating for the tow vehicle's braking
system operation is at the gross vehicle
weight rating, not the gross combined
weight rating.
Separate functioning brake systems
are required for safe control of towed
vehicles and trailers weighing more
than 1500 lb (680 kg) when loaded.
