Have you filled it with DEF? Have you had the DCU updated at a dodge dealership lately?

The vehicle is equipped with a “Low DEF” warning system that notifies the driver when the
level of DEF drops below approximately 2.5 gallons. The warning system includes warning
messages displayed by the EVIC and audible chimes. The first level warning displays the
message "Refill DEF Engine Will Not Restart In XXX Miles". If the vehicle is driven too long
with low DEF, the message “Refill DEF Engine Will Not Start” will be displayed. At that
point, the engine will no longer restart if it is shut off. A minimum of 2.5 gallons of DEF will
need to be added in order to be able to restart the engine.

If that doesn't work you will need a dealership level scantool (Witech) to read, erase, and update the DCU and ECM to the latest software..

Glad I could help,
