They have very little computer trouble, especially compared to GM cars.
There is a four digit code in the Body Computer and the Engine Computer. The Chrysler DRB3 scanner is used to copy the code from one of the computers, then it is entered into the new computer after it is installed. You have to be careful too with the computer you put in. If your car has factory-installed anti-theft, you can use any used computer. If it came from a car without anti-theft, it will learn that programming from the car's other computer. That upgrade programming can not be undone so from then on that computer will not work in any car without anti-theft.
If your car does not have anti-theft you must use a computer from another car without anti-theft. If you put one in from a car with anti-theft, it will teach that programming to the other computer, (the Body Computer in your case). At that point both computers will have to be replaced and programmed at the dealership before the engine will start.
If you buy a rebuilt computer from the dealer, they all come programmed for cars without anti-theft and will learn the upgrade programming from the other one if necessary.
