Terry suggesting I install the firmware update. I believe I did the correctly

Codes still present

He says I need to delete in diagnostic mode

Two questions:

Can Anybody provide color on the above codes
How do I enter diagnostic mode to delete


Any help much appreciated

Also, fuel economy seems horrible after install
