"When the ignition is cycled (turned off and then on), the air bag
indicator will remain lit for six seconds and then go out. If an SRS
fault exists, the air bag indicator will then flash the two-digit LFC.
The air bag indicator will flash the LFC five times, then it will
remain illuminated for the rest of the key cycle. The RCM will also
communicate the current and historical DTCs through the data link
connector (DLC), using the scan tool. If the air bag indicator does not
function, and the system detects a fault condition, the RCM will signal
the instrument cluster to activate an audible chime. The chime is a
series of five sets of five tone bursts. If the chime is heard, the SRS
and the air bag indicator require repair."

"LFCs are prioritized. If two or more faults occur at the same time,
the fault having the highest priority will be displayed first. After
that fault has been corrected, the next highest priority fault will be
displayed."

Working on air bags is hazardous. Special tools are required in most
cases. This should be left to a professional. You should also check
your warranty. The restraint warranty might be different than the
general warranty. I don't have a copy of the 2002 Warranty, but for
2001 the following applied:

"Safety Restraint Coverage

"Under your New Vehicle Limited Warranty, Safety Restraint Coverage
begins at the warranty start date and lasts for five years or 50,000
miles, whichever occurs first. During this coverage period, Ford Motor
Company or Ford Motor Vehicle Assurance Company warrants your
vehicle's safety belts and air bag Supplemental Restraint System
(SRS) against defects in factory-supplied materials or workmanship."
