Your instrument cluster may not be grounded. If your fuses are good, than you will need to check the grounding of the wires and make sure the wires are intact. A hairline crack in the ground will kill the cluster behind the cluster. You may have to use a magnify glass to see the crack. I would check the relays on the wires as well, not just in the fuse box, You will have to exhaust all your diagnostics to find the problems, You will need to check all your wiring and ground connections because I don't think its just one wire throwin all this off. The electrical system is fried almost like a reverse polarity on the battery which caused multiple things to short out

SOURCE: antitheft and battery lite on 2006 ford freestar

Try your spare key first. also, does the anti theft visual indicator (red flashing light) prove out, that is light for three seconds when key is turned to on.

here's some info.

Principles of Operation
The passive anti-theft system (PATS) uses a specially encoded ignition key. Each encoded ignition key contains a permanently installed electronic device called a transponder. Each transponder contains a unique electronic identification code out of over 18 billion, billion combinations.
The passive anti-theft system (PATS), also known as SecuriLock ®, uses radio frequency identification technology to deter a drive-away theft. This system is known as SecuriLock® in North America, Safeguard® in the U.K., and PATS in continental Europe. Passive means that it does not require any activity from the user.
The SecuriLock® System (PATS) is not compatible with NON-FORD remote start systems, which allow the vehicle to be started from outside the vehicle. These systems may reduce the vehicle security level, and also may cause no-start issues. If equipped, the remote start system must be removed before investigation of PATS-related, no-start issues.
Each encoded ignition key must be programmed into the vehicle's powertrain control module (PCM) before it can be used to start the engine. The correct ignition key is a different design than prior model years. Consult the Rotunda Key Ordering Guide for the correct part number. There are special diagnostic repair procedures described in this section that must be carried out if a new encoded ignition key is necessary.
This system contains a new feature named Unlimited Key Mode. This feature allows a customer to program more than eight keys to the vehicle if they request it. Each vehicle in Unlimited Key Mode is set up with a special unlimited transponder security key. This allows all the customer vehicles to share the same keys, but no other keys from outside can be used to operate the vehicles. For an individual customer, any randomly selected security key is acceptable. Refer to Unlimited Key Mode Programming in Key Programming Switch State Control in this section.
The PATS transceiver module communicates with the encoded ignition key. The module is located behind the steering column shroud and contains an antenna connected to a small electronics module. During each vehicle start sequence, the transceiver module reads the encoded ignition key identification code and sends data to the PCM.
The control functions are contained in the PCM. This module carries out all of the PATS functions, such as receiving the identification code from the encoded ignition key and controlling the engine enable. The PCM initiates the key interrogation sequence when the vehicle ignition switch is turned to RUN or START.
All elements of the PATS must be functional before the engine is allowed to start. If any of the components are not working correctly, the vehicle will not start.
PATS uses a visual theft indicator. The indicator will prove out for three seconds when the ignition switch is turned to RUN or START under normal operation. If there is a PATS concern, this indicator will either flash rapidly or glow steadily when the ignition switch is turned to RUN or START. The PATS system also flashes the theft indicator every two seconds at ignition OFF to act as a visual deterrent.
PATS will be activated and will disable the vehicle from starting if there is:

  • an incorrectly encoded ignition key.
  • a damaged encoded ignition key.
  • an unprogrammed key
  • a non-encoded key (key has no electronics).
  • damaged wiring.
  • a damaged transceiver.
  • a damaged PCM.

2006 Ford Freestar turns off every 700 miles, and after a couple of days I'm finally able to start it again. What is the problem?

I had the exact same problem, if you don't fix it ,it will get worse and leave you stranded at the most unoportune times. the problem is your inertia switch which is located on the right side of your cargo area in the compartment that holds your emergency jack. this switch has a button that you can depress to overide it's designed function is to cut off your gas supply upon an impact.It have become too sensitive and has failed. I hope that this helps you.
