Pretty much what David said.  Everybody has their own acronym including vehicle manufactures and scan tool manufactures. I generally use ECM to refer the computer that controls the engine functions which is what was replaced in his case. On this vehicle PCM would be an incorrect usage of that abbreviation because it has a separate transmission control module. 
For the most part if someone uses ECM, ECU or PCM they are referring to the same thing- the computer/module that controls the engine functions.  
As David said on vehicles where the engine computer and transmission computer are integrated into one unit, PCM would be the correct usage of that acronym and using TCM would be incorrect. But potato potaato. 
Obviously no one explain this to Autel when they were writing the softewate. 
 

This is a tutorial on syncing a used ECM to a Chrysler Town and Country using Autel Maxisys. This vehicle is a 2005 but the process is the same for pretty much any Chrysler. The newest I've done with the Maxisys is a 2016 Dodge Grand Caravan and the process was identical.

Next Automatic Selection

Make sure to manually enter the VIN and do not use the Read function. If you use the read function it will read the incorrect VIN out of the recently installed used ECM. After you enter the VIN click OK. 

Although not necessary, it's always a good idea to check and clear all fault codes so select Diagnosis. 

And then Auto Scan. 

If you want, after reading the fault codes, you can go into each module and review them or just use the Quick Erase function to clear them. 

Scroll down to Skim/Skreem and double click the line or single click the arrow.

Click OK

Enter the PIN and then click OK

If the PIN was entered correctly click OK

Click OK

Make sure the VIN is correct and click Yes

You're done, that's all there is to it.

PCM=Powertrain Control Module. It's supposed to be a single module that controls both the engine and transmission. In practice, most people don't really know what either term means and the distinction is unimportant, so the two terms are typically used interchangeably. Things get muddied further by people using ECM and ECU to mean electronic control module and unit, respectively, so PCM is often used to prevent any ambiguity about which particular module is being discussed.
