Looking it up this says the reductant tank assy.

WTF? Seriously? Any way to fix this myself or is it 'spend a bunch of money'

Or can I clear the code with the MM and it'll settle in on itself?

well shoot, now the minimax isn't working. All plugged in, turn the key on, it establishes communication. I scroll down and get into the DTC menu, select engine, but then all it does is say 'establishing communication with vehicle' Been on that screen for 5 minutes.

Sounds like a def pump, know about the whole assembly. But fill it with def and drive or high idle if it makes you. I've seen this going going back to stock.

I put a little def in there, cleared the code w/ the aftermarket stereo (MM wouldn't read codes for some reason) and drove it to the detail shop (get the fender flair scrub marks off.) Didn't come back.

Hopefully it will stay gone. Hope, hope, hope. Even talked nice to the truck and asked it not to be bad.

Def is cheap compared to being idle only mode! It shouldn't come back as long as there's def in it.

Hmm, fill w/ DEF. You thinking diluting the stuff that's been in there for 4yrs might help? Makes sense.

The dealer where I'm trading it is 3hr away too. I for sure don't want to get stranded on my way.

How many miles should I get before the code comes back if it is a serious mechanical issue?

did you recently update the minimax? I've heard that the updater was messed up and it has bricked a bunch of minimaxes.

no.

Saw that thread too.

MM just wouldn't read the DTCs. It seemed to 'return to stock' ok.

Used the aftermarket Stereo to clear the code, hopefully it won't come back.

No, the stereo has been a POS for a long time.

Code keeps popping up, did fill it w/ d e f

Seems to take two key cycles to trip the code. Anything I can do?
