What's the best thing to do when the ECM has failed. Reflashed or replaced. My truck started running funny checked the codes ton of them and one was 0606 ECM failure

What year is it? Try this: unhook both batteries and leave it sit for a little while, maybe the code will reset. Sometimes this will work. If not, I'm not sure what the deal is. I've been on dieseltruckresource.com for many years, and it's always been a very helpful board to me. Good luck!

Its an 02, Yeah I unhooked both batteries and let it sit for probably an hour. Looks like a new ECM more than likely

I'm a 20 year diesel tech. Ecm's aren't cheap and aren't returnable. Pay a qualified tech to confirm things before you go throwing that kind of $$ at it. I've seen poor grounds and other electrical gremlins cause similar problems.

Im a Cummins factory trained tech and will mirror what bilgerat said. Especially when a ton of codes come up, really check all grounds throughout. If all looks good with electrical system them a reflash will normally not change what you are experiencing. Pony up and pay a quality CUMMINS tech to do it, not some Joe Schmoe that can turn a wrench. That way all work is warrantied. Good luck brother.

+2, I'm Certified on Powerstroke and I can tell you if you go and put a new one in and you mess it up your SOL. It can fry your whole electrical system, I saw it on a brand new truck that a guy tried to do some mods on and he ended up taking the ECM out and then he fried the fuse panel..
