Incredible, are there codes in any of the modules?

 

Nope, No codes. I have now tried swapping out the PCM. No change. This Jeep is an epic fail for me....

 

Looks to me like it may be the ABS system. It could be a faulty front wheel sensor (or two), the manifold, or the PCM - but you said you replaced that.

Before you start taking target practice, you might try looking at a service manual for tips (if you already haven't). You can access Chilton's online for free at most libraries. In AZ, I can access the manual online from anywhere just by being a resident of Maricopa County.

 

Finally Fixed! Took to another local shop, Off Road Works/My Mechanic. They had it diagnosed and repaired in two days. Turns out that I had a defective Mopar repair part, The Hydraulic Control Unit wasn't releasing. I took them the original and they were able to clean it out and get it working. The second problem was a defective Brake Booster, we were able to warranty that through the shop we purchased it from. Moral of the story, DO YOUR FLUID MAINTENANCE on schedule.

Thanks for all the input and assistance provided!
