CM2350 Derate-Low DEF

[prejah72]

Thanks Rawze.
I understand what you are saying, been driving for the last 3 months, re-calibrating every couple of days. .
DEF Level Sensor in tank & Pump outside of pump was changed.
DEF doser was also cleaned, but did not solve the problem.
I know its quite stupid buts its costs me over $7K so far and counting....just been doing more oil changes to keep engine clean for now.

Codes are:
3712-SCR operator Inducement, Data valid but above normal range;
3714-Engine Torque Protection;
4677-DEF Tank Level Abnornmal;
4572-DEF Tank Temp;
6656-Unknown

How do I copy the files off the ECM?
