Dodge Repair Questions? Ask a Mechanic for Answers ASAP
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 thelevel of DEF drops below approximately 2.5 gallons. The warning system includes warningmessages displayed by the EVIC and audible chimes. The first level warning displays themessage "Refill DEF Engine Will Not Restart In XXX Miles". If the vehicle is driven too longwith low DEF, the message “Refill DEF Engine Will Not Start” will be displayed. At thatpoint, the engine will no longer restart if it is shut off. A minimum of 2.5 gallons of DEF willneed 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..
