DEF Warning After MM3 And Exhaust

[vrhunter]

Hello, everyone.

I got the files I needed to pull my stock ECM info last week.

I was finally able to get on my buddy's lift this morning and got the exhaust installed, and loaded the tune. Ironically, on my way to the shop, I got the refill DEF warning on the cluster, the DEF symbol illuminated, etc.

I assumed it would clear with the tune installed, but it is still there after a short 50-mile trip.

I can't find anything online regarding how to clear this message.

Thank you.

I would try disconnecting both batteries to clear the memory.

If the message persists, perform a full system scan and clear all trouble codes.

I think you have to load the tunes first BEFORE disconnecting and removing the exhaust etc.

Try installing your stock tune back and then reinstalling your tunes again.

Make sure your batteries are fully charged, or you have a charger connected before doing any of the above procedures.

Who did your tuning?

A reflash/reload after cc'ing the batteries fixed the message.

Thanks!
