Welcome to DF! Post your question in the 3rd gen Ram technical section. This section is for reporting Dodge Forum internet site issues.

 

Moved to the correct section and welcome to the site.

I'm on my mobile so I can't post everything but, if you look in my signature below you will find a link to the Service Manuals that are available and free to download. In them you will find those codes and how to troubleshoot them

 

So what codes are you getting now? Same as before replacing the ECM or different ones?
