sensor FORD EXPLORER 1997 2.G Owners Manual

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.
Several air bag system
components get hot after
inflation. Do not touch them
after inflation.
If the air bag is inflated,
the air bag will not
function again and must be
replaced immediately.Ifthe
air bag is not replaced, the
unrepaired area will increase the
risk of injury in a collision.
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
²and the electrical wiring which
connects the components.

The diagnostic module monitors its
own internal circuits and the
supplemental air bag electrical
system readiness (including the
impact sensors), the system wiring,
the air bag system readiness light,
the air bag back up power and the
air bag ignitors.
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 to theAir bag
readinesssection in the
Instrumentationchapter. 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 group of five beeps will be
heard. The tone pattern will
repeat periodically until the
problem and 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.
