Set Condition:

WARNING: This page is about a different car, the 2011 RAM Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

There are two conditions that will set this DTC. The first is if the DEF Dosing Control Unit detects that the DEF Tank temperature drops from above defrosted temperature, 41°F (5°C) to below frozen temperature, 0°F. The second is if there are any line heater continuity faults present for any of the heater circuits in the system.
