How To Reset DEF Message - Dodge Cummins

How to reset DEF message on a Dodge Ram (2016) with a Cummins Diesel Engine. The Service DEF System Message or P202e Code is a genuine game stopper and will put you in limp mode, but it doesn't NEED to be. I show you how I reset the DEF Limp mode code on my 2016 Dodge Cummins Diesel Engine to get home.
This may not FIX your problem... It is probably the DEF Injector that is giving you grief... BUT, it should get you home and to the repair shop WITHOUT a tow truck.
Good Luck, and as always, it didn't harm my truck but you are an adult now and need to take responsibility for your own decisions if you do this too.

This video was a life/$ saver I was able to make it from Denver to San Antonio 1, 000 miles on a road trip with the whole family.

I had a code reader and got the code P203C which could not be erased except from a dealer. My miles left were 125 and I was 200 miles from a dealer. Outrageous design to leave you stranded in desert areas without phone service especially pulling a 45 foot gooseneck. After truck made it to dealer it took two weeks to diagnose and repair, fortunately under warrenty. We made it to the dealer because we parked the truck overnight and somehow it reset itself and gave us enough additional miles to drive all the way to the dealer. 2017 2500 with 29, 000 miles on it. This has left me just shaking my head. The repair time and also being stranded are both outrageous. It was the DEF indicator in the pump that went bad requiring a new DEF pump.

You saved me and my wife after 3 days on this gas station working on my truck.
It did exactly what you said! We are jumping happy lol

My question would be why is there not a class action lawsuit against dodge for this bullshit. My friend spent 68, 000 dollars for her truck and now she can't drive it. Such bullshit.

[AHandleOnThings]

When I called the dealer they told me that I would have to drop my truck off and that they could get to it in about 12 days!
Now I don't know about you, but that stinks in my opinion. The dealer is busy so it isn't their fault but an EPA device putting me out of my truck for 12 days isn't acceptable. This work-around (used intelligently) will help to make this fault code a little easier to swallow. Or don't... the choice is ALWAYS yours! -Shane

It worked For me. It was giving me a P207F CODE. 5 miles per hour in 150 miles to Go to dealership. Thank you very much.

Ok, I’ve watched this video 8 times, I’m going to try this out and I’ll let you know!

[mojohauling]

Thanks for sharing, new to Ram, 17k miles with no trouble but I’m getting that scan tool for cheap insurance!

[nosty]

Just a lil tip. Drive as long as you want with the rear abs sensors unplugged. I have been on 33 miles til 5mph. For about 9 months. But mine is a 14 with a manual trans. So I pulled entire exhaust of just to test run it. Tows my 34’ enclosed with two race cars with ease. Now every warning light in the world is in. But runs perfect.

thank you for sharing this video. I’m working in the Grand Tetons for the summer and the light comes on. I found your video and it did the trick. We have a 2016 ram 2500. I was freaking out cause I am 1000 miles from home. There is no dodge dealer for 300 miles. I’m hoping I can get myself and my 32’ 5th wheel toy hauler home in October.

I was 10 miles from home last night with a Ram 3500 diesel when the miles ran out on the DEF warning. GOOD NEWS! It DOES NOT shut you down to 5mph immediately. You can still drive at speed as long as you do not shut the engine off or engage in "prolonged idle". However, as soon as you shut it off... you're in crawl mode. I need to try this fix.

[elliottshurepa]

Yeah kinda, I mean you can clear it, but it also depends on the issue. I have cleared this myself before, but once it would not go away. It’s because there was no resistance from a faulty DEF injector. Replaced it, cleared code. Gone for since. This might get you off the road, but pay attention to what the code is.

[Pillin]

I had this same issue and all because the DEF injector was faulty, took the truck to the dealership and they replaced it for a new one and problem fixed, I'm glad my truck is still under warranty so I didn't have to pay for it.

[WELDERUPGARAGE]

My 2015 ram 3500 6.7 has the P242F code that seems to be permanent.
I have tried all my scanners and searched online but still can’t resolve the issue. I have replaced the cat and the dpf but still the code persists. What can I do?

[sawituptx]

My code reader won't clear permanent code p2048 reductant injector circuit low Bank 1 unit 1

[Steadierpark]

I honestly don’t even want my warranty…the hassle and wait to get parts for using the damn machine I paid for is infuriating. And it’s all emissions! You would think the 68rfe would be the problem 😂 but that doesn’t even scare me compared to being stranded with my family in the middle of nowhere. Good advice…carry a freaking scan tool and a toolbox cause u never know.

[Flosstradamuss]

“10 other codes and performs service pop up”
“My codes are cleared”
😂😂

[rimwrecka]

I am trying this trick. Currently in Salt Lake City, trying to get home to San Antonio.

P2048 is saying that the code is permanent. (Using Innova 3040RS scanner tool)

Resetting all the codes granted me 4095 miles until 5mph.

Does this work on 2016 Nissan Titan Xd diesel

[emmieveeh]

This is great for future reference but what do we do on a 500 mile road trip when the message pops up 200+ miles from a dealer and we don’t have this device??? This is so dumb!
