I have a MTH 20-3369-2 PS3 steam engine 2 rail w/scale wheels cab #46234 Running on DCC tried loco #6234 and 03 on my DCC unit no response. No lights, sound or movement. Tried conventioal w/my Z4000 every thing works. I'm not familiar with MTH DCC O scale. I have heard MTH DCC is hard too program . I would like to remove that # and get it back to reset 03 . Any suggestions ?

You can reset it in conventional mode or with DCS. I don’t know if you can reset it while it is running under DCC. I did a quick google search came up with this:
Dumb question but you did check to make sure the DCS/DCC switch was set to DCC correct? It should be on the bottom of the tender.
Switch is on DCC
Phil I don't think a factory reset (conventional or DCS) will work. Engine works ok in conventional & DCS , but i will try to reset in conventional. I have to look at all possibilities. But the problem is in DCC mode. Thanks for responding.
if the loco was used it might have been programed to the cab number rather than the loco 3. also try 03 rather than just 3. I know some of my friends in HO have MTH DCC locos and they seem to be a nightmare to program and run with others in consists.
Jimmy, no problem. Hopefully, the reset will change the address to the factory default of 3. Then you can change the address to what you want it to be. I use the “long” address on all of my DCC locomotives. It isn’t difficult to change to the long address. First you need the values for CV 17 and CV 18. There are many calculators out there. The first one I found was at www.ruppweb.org. Just plug in 4263 or 4234 or whatever you want it to be. Then hit calculate and note the results for CV 17 and CV 18. Then follow the procedure below and you will successfully change the long address. Yes, this is a few more steps than TMCC or DCS but it isn’t hard to do. I hope this helps.
much easier to download JMRI (its free) . you can then read all CVs in the loco and change them on the computer screen with button clicks rather than all the long drawn out ways of doing it in the OPS mode. changing Cvs one at a time with the hand held is a pain , it also allows you to save your settings in case you loose them for some reason .
Thank you Rick,/ Hudson J1e/ Phil & Don The answer for my problem MTH PS3 2rail DCC no response To reset 55/55/55 reset got back to 03 Now I'm going to try a 4 digit address I'm checking the above threads. Thanks again
