1998 FORD F150 light

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 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.
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
Seating and safety restraints
63

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 series 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.
Disposal of air bags and air bag
equipped vehicles
For disposal of air bags or air bag
equipped vehicles, see your local
dealership or qualified technician.
Air bags MUST BE disposed of by
qualified personnel.

shudder while braking, felt mainly
in the steering wheel, the vehicle
most likely needs service.
The ABS operates by detecting the
onset of wheel lock up during
brake applications and
compensating for this tendency.
The front wheels are prevented
from locking even when the brakes
are firmly applied. The
accompanying illustration depicts
the advantage of an ABS equipped
vehicle (on bottom) to a non-ABS
equipped vehicle (on top) during
hard braking.
ABS warning lamp
The
ABSwarning lamp in the
instrument cluster illuminates for
about five seconds when starting
the vehicle. If an ABS fault is
detected, the light will remain on
and your vehicle should be
serviced as soon as possible.
Normal braking is still effective
unless the BRAKE warning lamp is
also illuminated.
Using ABS
²In an emergency or when
maximum efficiency from the
ABS is required, apply
continuous full force on the
brake. The ABS will be activated
immediately, thus allowing you
to retain full steering control of

more engine braking than
(Overdrive) and is useful when:
²driving with a heavy load
²towing a trailer up or down
steep hills
²additional engine downhill
braking is desired. If towing a
