Machine was on a job site and operated about “5 mins” after noticing DEF level was empty. Don’t think it’s a wiring issue due to everything working just fine before. Replaced Def Header and Exhaust Temperature Sensor (MIU804393) which cleared about 18 other pending codes. Engine still remained in derange mode. Is there any simple way to connect to engine and force regen with laptop via OBD2 adapter? I tried doing the park clean and service clean from service menu but says not required “soot level low”. Please help.

Not sure on Deere but those may be def inducement codes. If so the engine will automatically derate and will require a dealer diagnostic connection to force a regen and reset.
