Problem solved....thanks, everyone.
Thank you for your responses. I ended up taking it to the Chrysler Dealership that couldn't find the problem. They said I must have a short to ground somewhere after keeping my car for 3 days...and charging for additional diagnostics. They said the hand tool wasn't picking up communication. They supposedly went through half of the modules and didn't find the problem. Sorry, got long winded...but another auto repair shop, with the same information I gave Chysler, found the problem within a day and fixed it for less than what Chrysler charged. At any rate, the problem that my signal wire to my map had a short/burned/frayed. They repaired it. Problem Solved.
Once again, thanks.
