Need a complete machine serial number. for accurate information

It means the engine is in derate.

Did you scroll through the monitor into codes? Need to see what codes are in there, both stored and active.

Def system fault. And SCR system very high. Troubleshooting required. I had John Deere fix it a few weeks ago and they installed new pay load on the ECU and worked fine for a week. Code came back on. Jd tech said he honestly did not know what was wrong with it. That the pay load got rid of the problem when he installed it. A week later same code. Serial number is 1T0333GMLHF313028

These two statements tell me nothing. I need specific code numbers (SPN and FMI, up to six digits before the decimal and 2 after the decimal). The code you already supplied only means the machine is derated and that something else is the issue.
If you key on, then press and hold the menu button for approximately 5 seconds until the words "SERVICE MENU" appear in the screen, then not only can you read the codes, you can also clear them. After you record the codes, clear them, then run it and see what comes back. Either way, post "ALL" codes listed under active and stored by their numbers.
