Good afternoon and welcome to JustAnswer!!

My name is ***** ***** I have worked for a Chrysler-Dodge-Jeep dealership for 19 years and I will do my best to help.

The only way I will be able to help is if you give me the codes that are active in the ECM-PCM-DCU module.. Without the codes it's anyone's guess as to what's wrong. I repair DEF issues weekly here at the dealership but again I will need the codes to know what is wrong..

Talk soon,
