Removal
NOTE: The steps included in the SJB removal and installation procedure are critical to restoring the vehicle security and tire pressure monitoring systems to normal operation. A new SJB is delivered in manufacturing mode with 6 pre-set diagnostic trouble codes (DTCs) related to the tire pressure monitoring system. The presence of these DTCs requires the installation procedures be followed in order to clear the DTCs and enable normal SJB operations.
NOTE: Prior to the removal of the SJB, it is necessary to upload the module configuration information to the diagnostic tool. This information must be downloaded to the new SJB after installation. For additional information, refer to Section 418-01 .

If the car is running good no engine problems or poor gas mileage I wouldn't worry about it. This is done as preventive maintenance. Every tune-up parts have replacement recommended periods. Ignition components, all filters and lubricants should all be replaced the most every six moths depending on how much you drive. Its all common sense if you check your oil and its black its time to change it. If your brakes are screeching same thing and if it been six month probably well over 15,000 miles since you replaced the fuel filter it'll be a good idea to change it.

Check this and other information in the Jeep-XJ-2000-08w-Wiring-Diagrams ; Section 8W-12, page 57 and next.
Hope helps.
SOURCE: mechanic is telling me that the smart junction box
The Smart Junction Box is an additional item in the circuitry that controls power distribution to all of the lighting and a bunch of other ancillary systems on your Freestar. The "Smart" in the name is an oxymoron, it isn't smart at all. It takes input from a switch and then decides what needs to get power, like headlights, with tail, turn and parking lights. This used to be done in the switch assembly, and I guess that Ford decided that was too simple. Find out what is wrong with the SJB, and think about having it replaced, or, do what I am, splicing into a circuit that mimics the behavior of the tag lights. My license lamps are out, even after replacing the harness and bulbs, on a 2004 Freestar, and I feel your pain.
SOURCE: Where is the smart junction box located
Hi there:
According with the manual, the Power Distribution Box is located in the engine compartment. The power distribution box contains high-current fuses that protect your vehicle's main electrical systems from overloads.
Also, the Passenger Compartment Fuse Panel, that is located below and to the left of the steering wheel by the brake pedal. Remove the panel cover to access the fuses.
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
Thank you for using FixYa, have a nice day.
