Unfortunately, it's not possible to diagnose the problem just with the code. The code it's not common and the factory service manual suggest doing more tests to accurately diagnose the problem. I'm sorry you have this problem, but my only suggestion is to take your vehicle to another Jeep dealer. Not all the dealers have the proper skill to diagnose an uncommon problem.
