Re: 2011 Grand Cherokee
Almost impossible to say on what trouble code the PCM has stored unless you have someone perform a diagnostic scan to retrieve the codes. I am not 100% certain, but I'm taking a guess and thinking the ECO symbol deletes whenever there is a active trouble code. It should return when the problem is corrected.

What engine do you have and how many miles are on it?

"ECO" symbol disappeared when I had a CEL light as well. The moment the check engine light went out, it came back. Fault code was still stored in the car's computer though.
