RE: how to DDE4/EDC15C4 DTC off??
Greatings my friend...the easiest way for that is with program for removing DTCS, you have various options for that (Mtx Dtc Remove, Vag, Psa, Ford Dtc Killer...) 

1- identify Dtc (generic code)
2-Read Ecu
3- Use one of the various programs
4- open file remove Dtc
5- never forget you must know correct the checksum of the new file (the Dtc removers dont do that for you), so you must also know how to use another program for that, or the luck of the program that you are using to flash ECU do that automatically...
6-also always good to compare both files, sometines this programs really mess up the Dtcs table

But also going to warning you that this sometimes is the worst nightmare of a mechanic...i work in a garage and is a headache when you try to diagnostic and have no dtcs cause someone having mess up the ECU...

Best Regards...and good Luck on your learning

Knowledge is having the right answer...Intelligence is asking the right question...
