My 2005 Ford Freestar beeps 5 times, while driving, it repeats 4 more times, then stops, after driving about half an hour, it begins again, I read on the internet where it could be a blown ABS fuse, so I went to Auto Zone to get a replacement, they said the ABS fuse was at position 18, I could not find that, neither could he, so, he removed the battery cable, his idea was that, that would reset the panel, and if it was the fuse, then my issue would be resolved, if not, then he believes it may be a tire pressure monitoring system sensor, so, before I go out and start buying things, does anyone have a more definitive solution?

Determining if the Personal Safety System is operational
The Personal Safety System uses a warning light in the instrument
cluster or a back-up tone to indicate the condition of the system. Refer
to the Warning light section in the Instrument cluster chapter. Routine
maintenance of the Personal Safety System is not required.
The Restraints Control Module (RCM) monitors its own internal circuits
and the circuits for the airbag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, driver seat
position sensor, and passenger occupant classification sensor. In addition,
the RCM also monitors the restraints warning light in the instrument
cluster. A difficulty with the system is indicated by one or more of the
following.
• The warning light will either flash or stay lit.
• The warning light will not illuminate immediately after ignition is
turned on.
• A series of five beeps will be heard. The tone pattern will repeat <-----------------------------------------
periodically until the problem and warning light are repaired.
If any of these things happen, even intermittently, have the Personal
Safety System serviced at an authorized dealer immediately. Unless
serviced, the system may not function properly in the event of a
collision.


Fuse position 18 is for the ABS and is in the passenger fuse panel under the steering wheel.

The fuse panel is located below and to the left of the steering wheel by
the brake pedal.
