2002 FORD E SERIES sensor

Additional equipment may affect the performance of the air bag
sensors increasing the risk of injury. Please refer to the Body
Builders Layout Book for instructions about the appropriate installation
of additional equipment.
Children and air bags
For additional important safety
information, read all information on
safety restraints in this guide.
Children must always be properly
restrained. Accident statistics
suggest that children are safer when
properly restrained in the rear
seating positions than in the front
seating position. Failure to follow
these instructions may increase the
risk of injury in a collision.
Air bags can kill or injure a
child in a child seat.
NEVERplace a rear-facing child
seat in front of an active air bag. If
you must use a forward-facing
child seat in the front seat, move
the seat all the way back.

How does the air bag supplemental restraint system work?
The air bag SRS is designed to
activate when the vehicle sustains
longitudinal deceleration sufficient
to cause the sensors to close an
electrical circuit that initiates air
bag inflation.
The fact that the air bags did not
inflate in a collision does not mean
that something is wrong with the
system. Rather, it means the forces
were not of the type sufficient to
cause activation. Air bags are designed to inflate in frontal and
near-frontal collisions, not rollover, side-impact, or rear-impacts unless
the collision causes sufficient longitudinal deceleration.
The air bags inflate and deflate
rapidly upon activation. After air bag
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 (e.g., baking
soda) that result from the
combustion process that inflates the
air bag. 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 air bag may also cause abrasions, swelling or temporary
hearing loss. Because air bags 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, particularly to occupants who
are not properly restrained or are otherwise out of position at the time
of air bag deployment. Thus, it is extremely important that occupants be
properly restrained as far away from the air bag module as possible while
maintaining vehicle control.

The SRS consists of:
²driver and passenger air bag modules (which include the inflators and
air bags)
²one or more impact and safing sensors
²a readiness light and tone
²a diagnostic module
²and the electrical wiring which connects the components
The diagnostic module monitors its own internal circuits and the
supplemental air bag electrical system warning (including the impact
sensors), the system wiring, the air bag system readiness light, the air
bag back up power and the air bag ignitors.
Several air bag system components get hot after inflation. Do not
touch them after inflation.
If the air bag has deployed,the air bag will not function
again and must be replaced immediately.If the air bag is not
replaced, the unrepaired area will increase the risk of injury in a
collision.
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer toAir bag readinesssection
in theInstrument clusterchapter. Routine maintenance of the air bag is
not required.
A difficulty with the system is indicated by one or more of the following:
²The readiness light will either
flash or stay lit.
²The readiness light will not
illuminate immediately after ignition is turned on.
²A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and/or light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at your dealership or by a qualified technician immediately. Unless
serviced, the system may not function properly in the event of a
collision.
