Engine Code

Does anyone know what this code on isx-15 is for? Was pulling out of garage to test satellite install and now this!

I am guessing it is a battery voltage warning after starting it. Did it clear after shutting down and restarting?
3031 4 231 Aftertreatment 1 Diesel Exhaust Fluid Tank Temperature Voltage
Below Normal, Or Shorted To Low Source
1677 Aftertreatment 1 Diesel Exhaust
Fluid Tank Temperature Sensor
- Voltage below normal, or shorted to low source
3031 3 232 Aftertreatment 1 Diesel Exhaust Fluid Tank Temperature Voltage
Above Normal, Or Shorted To High Source
1678 Aftertreatment 1 Diesel Exhaust
Fluid Tank Temperature Sensor
- Voltage above normal, or shorted to high source
3031 2 233 Aftertreatment 1 Diesel Exhaust Fluid Tank Temperature Data
Erratic, Intermittent Or Incorrect
1679 Aftertreatment 1 Diesel Exhaust Fluid Tank Temperature -
Data erratic, intermittent or incorrect

Best info I could find.......hope it helps.

3031-9 did not clear out and looking through Silverleaf it was showing -41 degrees for DEF fluid. Checked all wiring and connectors, live 4 miles from Cummins repair shop so will attempt to take it to them on Monday. Strange thing is just last week had DEF dozing pump go out in my 17 Ram with 6.7 diesel and now on our 17 LA a DEF temperature sensor. Goodness this emissions crud is for the birds!

Sounds like ya got it narrowed down David, Great ! I agree, it is always something with all this emission stuff.......I like everything about the later equipment......but not all that junk. Hopefully it is a quick and easy fix and not to much expense, Warranty? Travel safe!
