My daughters jeep had the same problem. We fixed by finding the wires that run beside the manifold down under the car. The conduit that have the wires in it was worn away because of resting up against the manifold, causing the wires to short the system out. Once I replaced the conduit and taped the wires it has not shorted out again. By the way, the Jeep dealer couldn't find the problem.

The fuse it doing it's job, you have a short ( Wire that is connected to a ground, that draws too much power )
If you have an electrical schematic ( Repair manual ) find out which wires are connected to that fuse and check them for any chaffing, cuts, unnesassary twists, or corrosion.
If you have a ohm-meter, isolate the system ( by disconnecting the fuse, and other connections. Then check for any resistance on wires that should not be connected ( because you disconnected them ) by having one Lead on the wire's connector and the other meter-lead on your car's frame. A good wire will not have continuity if it is isolated.

Hi, the asd relay powers a lot of things. You may have to unhook some stuff to figure out what is causing the problem. Is your engine light on? I think the O2 sensor heaters are on that fuse but they should throw a trouble code, as the PCM monitors that current. You could unhook the EVAP leak detection pump--I think it's in the rear bumper on driver's side. The injectors are on the fuse as well as the alternator stator current. Perhaps you could disconnect the pump, O2 sensors, and the alternator (just the connector--not the charge wire). Then start the car and hook stuff back one at a time until the fuse blows. Make sense? Let me know if you have questions and thanks for using FixYa.

For the ASD fuse to go out the short will be a wire wick problem, The ASD fuse and the nearest ground is the Oxygen heater ground, it in the wire harness and its touching .I am telling you this because obviously you ll have to get it repaired and I want you to know were the problem will reside at,so this way when you go to a shop your armed and they will know that you know your stuff. And your repair will be a sucess
