These seem to pertain to the derate condition 2258.7 2259.9 What I have for manuals don't identify these codes Thanks for any help or advice.
Found another stored code 2260.1 Also unlisted in the info I have
Or maybe I'm reading this wrong and it's not a code but the hour mark when the 1569.31 code occurred
Post a picture of what you are seeing.
Problems solved by flashing computers and correcting Hr meter mismatch between EMU and ECU Thanks for all your help
