Default 2002 PCM? ECM? same thing?

ok so i did a search and couldnt find anything on it but:

in the 2002 Ram Sport with the 4.7, is the ECM the same thing as the PCM? i wanted to reset it so it could relearn all its parameters but i didnt see anything in the fuse box saying PCM only ECM/SKIM. is that the same thing?

may be a stupid question but like my tag name says, im new to all of this...

much appreciated!

yes, they are the same thing. ECU=electronic control unit. ECM=electronic control module. PCM=power control module. just all different ways to say it
