MTH GP40 won't work with DCS

Try this one... Must be tiu #1 (a one blinker) with no other engines on the track... software version 4.1 or higher. Make sure it's not already added to the remote someplace... inactive list perhaps.

Menu/System / engine set up/ recover engine.....  If the  engine is found you'll still have to add it to the remote.   

If you can  get the engine added try a feature reset... Menu/advanced/ reset engine/ feature reset........... good luck.

Sounds like a bad audio amp also, that can be repaired.  I do repairs if you need assistance.  E-mail is in my profile.  G

Thank you both. I had no luck. I really like this engine as I have it weathered pretty nice. That said I am not ready to invest much money in getting it fixed. I might put it on the buy/sell forum for someone who likes to fix DCS trains or just want a quiet conventional engine

I wouldn't give up just yet. Maybe the lash-up bug got this one... but first what message did the recover engine feature give. ?   There is a bug that if a engine has the same ID number as a lash-up ,the engine will not add to the remote. The fix is to move the lash-up to a different ID. Any lash-ups?

Nope. No lash-ups anymore. Over the winter freeze last week, I cleared all my remotes and reprogrammed them on a temporary test track set up in my living room. Everything went well except for this one, which I have had trouble with.

Thanks you for all you help, it will be on the buy/sell today if anyone is interested.

Nice looking unit. There may be a simpler explanation for the lack of sounds -- bad speaker. There was a crop of bad speakers from MTH's supplier, particularly the 4-Ohm speakers used in the 3-volt locomotives. I have two to 4-ohm speakers to replace, plus a couple of 16-ohm speakers that have gone south in 5-volt units. I've been looking into pairing up H.O. enclosed speakers as their sound has improved greatly over the past couple of years and there are some good places I can position them for better sound output.

As for not getting it into the remote. If the remote has been reset and completely cleared of engines, it should add. Otherwise it might have an address of an existing engine and the remote thinks it's already there. I'd also consider tethering the remote to the TIU where the locomotive is if multiple TIUs are on the layout.

Since we have multiple TIUs and there are often DCS trains running, what we've started doing  is tethering the remote to TIU #1. This prevents the remote from "reaching out" to other TIUs and grabbing another locomotive and potentially changing its address (real fun). When tethered, a remote doesn't use it's radio transmitter. I've designed a test/setup bench but haven't built it yet, which will be where we will add/edit locomotives rather than on a track in the staging yard.

Hope this helps.

Sounds like more then a speaker if it can't be found in DCS. It is an older 5V board as the 3V boards started with the 2004 catalog. Nice looking engine but the price of boards............
