Control Module

What is the integrated control module in a car?
I have a 1994 Mercury Sable has been overheating. I took it to Tuffy and said integration seems to control module or relay module has gone bad. I do not charge anything to check out the car because my car is so old their software is not compatible. I am pretty mechanically minded and car-literate, but I've never heard of this part and can not find anything about it online. From I understand that regulates the fuel pump, cooling fan, and some other things.
I also checked and could not find the term either. From experience, the fuel pump is controlled by the ECM / PCM, on some cars. ECM is the electronic control module. PCM power control means Module.
