Freightliner DEF Check Engine Light FIX!!!
ฝัง
- เผยแพร่เมื่อ 4 ต.ค. 2024
- If your Freightliner's check engine lights come on while pulling a heavy load, then this will more than likely fix your problem.
This problem usually happens for me when I have a heavy load, pulling hills and got DEF fluid from a bigger truck stop.
The three check engine light codes:
1. Emissions System Problem Detected Service Engine - SPN 4364 FMI 18
2. Poor Quality DEF Check DEF - SPN 3364 FMI 2
3. Service Engine Emissions System 25% Derate. SPN 5246
*UPDATE*
Since making this video, I've tried a couple of additives that seem to work pretty well for cleaning the DPF system.
I also researched the DPF system via Freightliner's website and also spoke to a couple of shop managers at various Freightliner locations.
They've all pretty much said the same thing, that the DPF filters are supposed to last at least 400,000 miles.
So I decided to try the Lucas Deep clean 64oz which you can check out here: amzn.to/30cE37Z and
HotShots Secrets:
amzn.to/34Ydgfm
Since adding them, I haven't had to Regen once and that was about a month ago. I've hauled a couple of 42,000+ loads up hills and mountains with no problem.
So check those out if that's the problem you're having! Best of luck!

Thanks for the video. A year after you posted it is still helping drivers out here.
IT WORKED!!!!! You saved me thousands on the tow and it’s snowing here in Ohio🥶
Thank you my brother God bless
So I just bought a 2016 Cascadia and the first time I put DEF in it I get this issue. I’m currently 20 mins in to the Regen and the light stopped blinking and the Check Engine light is out. So far so good. Will let you know how it ends up with an edit.
(Edit): It worked. So far so good. Thanks a ton bro, you saved me a massive amount of stress and aggravation. Four years later, still saving lives with this video. 🤙🏻
I fixed my problem with poor def quality. He is how you fix it. First take your truck to close truck stop ask him to change your def filter lu7103 it costs 32 dollars then do rgen for about 40 minutes and you see all check engine clear up
Just when I thought I was doing alright using DEF from the pump... Ugh!
In regen now with my fingers crossed.
Thank you for making the video. Second time in the second truck it saved me!
Had no idea about the override and regen button. Thank you
Thank you for making this video. I've been fighting this problem for 2 years. Have spent thousands on needless repairs. All I needed was a regen. Worked great.
Dave Doherty I’m glad it could help!
It's never just a regen and if you've been bringing it to mechanics for two years and have the same problem, you've been going to a garbage shop. Look it up. Regents fix nothing. They are used for diagnostics, ash and soot volume and recalibrations per all oem. If you'd like to learn more and get a basic knowledge of the after treatment systems cummins is the most open to their after treatment systems seeing how all after treatment systems in use now are based off their design.
You just saved my whole week and day my dude thanks a lot ! Doing Gods work 😂
Thanks a lot brother you made my day very easy i was stuck in Ohio with the same freaky problem but i saved my day and night and come back to Canada safely you are awesome God bless you buddy 👍👍👍👍👍
Thank you for making this video man this is awesome I had this problem a few months and and spend over two thousand fixing it and having the same problem now and returning my truck as I type this thank you man ...
Wow..Thy.big help driver
Ty bro I’m a owner operator and you just saved me a trip to Tom Neil in Jacksonville Florida... I just now had this exact issue and called them to get a quote to check it.. $290 just to check smh.. I’m glad I checked TH-cam n seen your video!! I regenerated and my lights went out fixing the problem!!! Ty bro n God bless you and your family!! 🙏🏾
It's not fixed, only delayed I guarantee it. Regens do not fix anything per oem. First thing they teach you in a after treatment class. Strictly used for diagnostics, lowering ask and soot levels and recalibrations on the systems and major repairs completed.
@@stevenliberadzki9160 still going strong bro 👍🏾
Thanks bro this just got me back on the road
T D no problem!
My man I really thank you so much I just call love for forstrgen and I’m like let me check the code I see ur video and just did a rgen by it self thank you u saved me 150 just in first 3-4 minutes
ابن ادم وا بت ادم you’re very welcome
Thanks for posting this video man, it helped me today 🤘🤘
Bro!!! Thank yoh so much for this video!!! Got me rollin' again!
Honeyyy! 💗😊 I just did Chicago to Lubbock at 55mph! Same issue. I could kiss you right now! Domoarígato!!!
Awesome video brother, Thanks a mill just used your method, it worked when I did the Override and RGEN 🙌🙌🙌👏👏👏 #TruckersUnited
Much as gracias bro you saved me time,money and headache it work
I get that issue a lot because it's an old truck the boss bought at auction, and won't change the darned filters. >.< But so you know, had to look it up when it started happening, FMI 18 SPN 4364 (and 3364 if I remember that other one right) come up as "bad DEF or faulty NOX sensor" so basically it means your NOX levels are too high. Could be bad sensors, bad filters, or even an impending One Box failure (had that one cripple me once). BTW that engine light with no lettering on it is the "Maintenance Needed" light, a lower-level version of the Check Engine light. Usually gets thrown when a minor issue like the code 4364 happens.
Did learn something new in this video... I hate how we can't trigger a regen unless the filter light is flashing, or we get the CE/DEF lights... never thought to hold regen and the override, gonna try it next chance I get, thank you!
[edit to correct a typo, meant to say 3364 not 3374, and I looked it up, that is the other code I was getting, seem to come as a pair, for me, get both at same time]
Thank you so much You saved me on a toll bill I love you I swear
I have this problem all the time. A medium to heavy load and a steep grade. The two check engine lights come on and the DEF light starts to blink. I get to the top and safely pull over and I do a regeneration. I just paid to have a DEF Awning installed. I just paid to have my DEF filter pulled, Baked and replaced. Still have this problem. The other day I was alarmed because the regeneration did not fix the problem. I decided to derate (limp mode) to a Freightliner dealer 15 miles away. On my way to the dealer it all disappeared. Drove 300 miles home and never had another problem. PLEASE ADVISE. 2014 Cascadia, DD15.
It get a hickup. Then all good. Comes on usually up a hill under heavy load. Just run on a flat area. All goes away
How did you end up fixing your problem? My truck is doing the same thing
@@jacobhernandez13b Hi! Did you fix this problem? If yes, where was a problem? Thank you
@gennadypopov4497 having the same issue about 40 mins from home while I'm resetting for the next days work. Looked up another video and he was saying that the SCR/ONE box harness was the likely culprit along with some faulty sensors. He said the harness is like 150-250$ and it's fairly easy to replace. It's 10 clips and dumping the old def and using boxed def will help this issue. I'm trying that tomorrow given I can find that harness. Will update in about 48 hrs
Works! Thank you so much for saving my time and money! 💪
WOW! I tried Regen button - never works, purchased dddl 8.12 + nexiq usb link , doing it through dealer software, but if I need just to use 2 buttons - that will speedup the process! Thank you!
Thanks for the feedback!
Thanks so much my Brother!!!!
You're welcome
Thanks bro you helped me a lot with this video
Thank you for the video.
How did you get the check engine light to go off?
I had this issue when i pumped DEF from pump, now i change my filter every year & out from 2.5 gallon haven't had a problem since.
Mine finally just regened. I was checking the stupid def filter by the def tank.
You have to cycle 10 times to clear the engine light
Works for me
Ok we will try it thank you !!!!
It goes off after so many miles
Appreciate that really great information
Great video
Bro thank you very much for your video it worked for me
CHANGE THE DEF FILTER ON THE DEF TANK
Nice it help me Thank you!!!
Thanks that’s very helpful
Thank you
That engine override with the regen button doesn't work for me anyway
Mines don’t work for me either
Mine ither 🤬
Thanks Bro 👊🏾
We're you able to get that other light to go out.. I'm having the same issue.. no codes
Some problems won't give fault codes but are related to other issues. See a professional shop that has full resources to dd diagnostics.
Thx bro you help me lots
I have same problem.All 3 check engine lights came on and def light is blinking.Did regen but still lights on and can't drive more that 5mph🤦🏻.Should I regen many times?Thanks
It is happening to me, how did you resolve the issue. Please reply
You just helped me thanks bro!!
James smith you’re welcome. Glad I could help!
Thanks you for your información i hay the same problemas first thing im gonig to do is going to buy that oil
Thank you so much
Why mine don’t do it. I press and hold both regon and OVRD buttons? 2014 cascadia
My temperature is about 160 right now. Is it too low?
Quick question so whats actual fix for this problem
David Brooks ultimately getting them cleaned or replacing them
We dont actually know because it was not properly scanned. Bottom line. Need to see the date on filters when replaced last. Pto time on unit. Are all after treatment parts running in the correct range i.e. hours on nox sensors ect. You don't do swapnoatics on a 5k part like a dpf. Have it scanned threw dd diagnostics tool. A regen is used for diagnostics purposes. Tells the technician all he needs to know. Temps, dosing times ect. Seek a true professional.
Literally getting the def tank taken out. If you bring it to freightliner they will at least charge you 5k and the problem won’t be solved.
Thank you for this video .
I have frightlaner Cascadia 2016
I have this issue from time to time specially when I'm driving up to Hills exactly same the one you showing
And I keep driving for another 20 miles 30 miles and disappear
But It's not making me comfortable with this issue
So you think the DPF filters needs to get clean up ? Or something else
Mah A yep! It’s only a matter of time before you’ll get the code that the filters need to be replaced. How many miles do you have?
My truck have 400k miles
Mah A oh ok, I had mine replaced in January. So about 4 months after this video.
@@sixfiguretrucking
how much you paid for replacing the filter ?
@@sixfiguretrucking
And how you see the truck after you replaced the new one ?
How long this last for without the light on def and did it ever came back on again I just got this issue your help is needed like do you do this process again when it happens again let me know thanks for your video I give u a shoutout on my next video homie
Trucker Dave 215 from my experience it lasts a couple of weeks. But that’s because I try to run light in mountainous areas. Also if you do a lot of idling you’ll have to regen more also. I eventually had to get them baked out. It cost around $2300 which is crazy! I recommend trying the Lucas deep clean, that one worked best to slow it down but you’ll probably have to do a bottle a week if it’s really bad. Anyway, I hope that helps and best of luck.
Six Figure Trucking thanks man I had to force regend some lights came off but I drove about 100 miles when def lights came back on and stop engine light came on and it when to derate mode to 5mph I call roadside and it was the dozer wire harness under passenger seat near dpf filter cost 200 but labor and coming out to me was 1300 the wire was cut form rubbing on metal thanks for video
Trucker Dave 215 no problem! I’m glad you got it squared away though!
@@sixfiguretrucking I just now had this same problem but with your steps In your video my check engine light went away and my(Def light stoped blinking) which is great and I can at least get to a good shop.. but I have a questions When you say you spent $2300? On what. ?? And did your problem get fix correctly after you spent that $2300. And from the time you made this video did you solid miter light go away once you started driving again. ?
@@jacktownkid7692 the $2300 was for cleaning/baking the filters.
is not just mileage is also idling time
My truck still not REGN
Worst case scenario your DPF filters are messed up. Plugged, cracked, melted. Im living it. Not good when you pay out of pocket.
I had those 2 on O did regen, now just after that I have red engine light anyone please
Engine light usually stays on for a day or so. You got lucky that the truck regen itself, need to invest in a regen tool. #OTRPERFORMANCE
Hi Francisco l have one cascadia 2011 but fabr. 2010. I gare probleme bys pass 5 mth seepd. I need move to mecanic. But this truck is diferent sistem
Im having this same problem now. It happens every trip..and if this happens by getting def from big truck stops then where we suppose get it from?..
Get it at Walmart. Blue def
@@juniorcastaneda6018 thanks tho but my truck is running good now. Freightliner had to change the whole One Box n dpf fitlers.. The One Box wasnt holding high temperature thats why it was having that problem.
See what the manufacture recommends. Job done.
@@sjkang21 freightliner had a campaign on the one boxes. The welds were not done correctly. Look into it. At our shop alone in the past two years we have changed hundred s for that reason and were refunded. I believe there is a year makes and models it falls under.
Mine just auto regened and it is still there but it hasn't derated on me yet lol I know its early but how much longer do you think I have before it derates?
James Cannon depends on the area, for mine I had to do 2 regens back to back in order for the light to go away.
If your ash or soot volume is too high it can take two regends. Your dpf's are supposed to last 5 years assuming you ran the truck and the after treatment system is running correctly. Low idle time is a must. Any mechanic with dd diagnostics can see the pto time on the truck. Every 10 hours idle equals 1 mile to the trucks dricmvetrain and after treatment. Do your regens! Don't stop them!
Great video I tried but it didn’t work for me
Update it worked after 2nd Regen thanks
No problem! Glad it worked
Thanks u help me
I do have problemsEEC spn 3936 fmi 18 and I cannot do a region or generated by it self Any advice please thank you
ابن ادم وا بت ادم it’s saying that it’s a leak. That code is saying that the pressure is out of the normal range.
Six Figure Trucking is it air leak or def
ابن ادم وا بت ادم it’s more than likely a leak around the DPF filter
Six Figure Trucking well late see what I can do with it thank you anyway
Lol. Pressure out of range eh means an air leak. If you're not a mechanic and I mean certified you shouldn't be giving this kind of advice. Like me giving medical advice. Js I'm not a doctor.
I got same code went to dealer they change Nox sensor on my truck charge me $1500
I'm sure most of that money was spent on the diagnostics aspect of that. Nox sensors are the most changed part in the after treatment system. Unfortunately that is a down stream problem. Which means something upstream is the real issue 9/10 times. Gl with that.
Did that fix your problem?
Did this fix your problem cos i have the same issue and they told me the same
Keeps coming back ?
Fred C what do you mean?
Tkns
Def level Spence change fix that's problem
I tried the override and it didn't work, any other advice
Take it to a professional. Glad it didn't work. It stopped you for a reason. So you don't blow your truck up.
@@stevenliberadzki9160 stfu
How did you get the engine light to go off?
Brother Jaypal the best way to do it is after you've cleared the codes, disconnect the batteries for about 10 mins and that should do it.
Thanks six figure!
Brother Jaypal no problem
Can't hear anything
Check your volume! It's working on my end.
@@sixfiguretrucking thanks for the information by the way im RGEN the truck now as we speak 🙃🙏🏿
Were you able to get the volume squared away?
@@sixfiguretrucking no still low
Mine does it every day. I have to stop and regen every day
It’s probably time to get the filters cleaned or replaced.
@@sixfiguretrucking brand new. Just a shitty Freightliner
Poor audio
Can’t hear you Buddy.
Speak up next time pls
We have the same exact truck. 2016 DD15. Do you have the DT12 automatic too? I've been dealing with this same issue. I live in CT, I always keep my DEF tank full & I always fill it at the TA off of exit 28 Milldale, CT. I think you've solved my issue after all of this trouble for the past 6 months. Shoot me a text, 203-906-9979.
I actually just had to do a regen yesterday... the override button is news to me.
Cycling is 5 times won't usually work, I believe it's timing. After you do your regen, you're left with one check engine light that will go off in a day or 2. I have the same problem when pulling heavy loads up 287. It's so calculated that it starts flashing in the same exact spot (I'm a local owner of, intermodal), I'm going to start buying the boxed DEF. I've been doing the wrong thing all along. 1. By only using pumped DEF at TA's. 2. Topping it off everytime I get fuel, I'm praying this works
Thanks again for this video.
It saved me a lot of misdirection, etc... it's such a weird problem.
My apologies for the delay. But I updated the description on this video. But since then I tried 2 different additives: 1. Lucas Deep Clean & 2. HotShots Secrets Diesel. I have only had to Regen once! It helps to clean the DPF system and helps the fuel burn cleaner. I hope this helps.
@@sixfiguretrucking thank you. What kind of DEF have you been using since then?
Check engine light is gone lol still there wtf lol
jalen woods yeah, I forgot the name of the light, but it stays on for a while. It’s not the check engine light though.
It's a mil light that takes key cycles to retire. This issue is not " fixed".
@@stevenliberadzki9160 my MIL light is on. Have a 2018 freightliner old body frame model. 435110 miles. When I go to diagnostics screen no active codes. Idle hours are very minimal.
