ATS One Box Design Freightliner Cascadia 2012 to 2019: ATD Explained.
HTML-код
- Опубликовано: 8 мар 2019
- We are going to find out how your SCR box, DPF Box, ATD or whatever other name you have for it, works with a real example. The proper name is AfterTreatment System Box that is the way Freightliner called it.
Note: There are two main differences between the older (2012 to 2016) and newer (2017 and up)
1. SCR Inlet Temperature Sensor was removed.
2. Soot Sensor was introduced. Which one is around the same area of the Outlet Nox Sensor. I am talking at the end of the ATS.
3. It might be other differences, not sure about the size of the filters compare to the old design but for now those are the main I found.

Best video so far I’ve seen explaining this nightmare BS. Thank you!
Glad you liked it!
2nd year diesel tech student here. Your video helped me thank you.
Glad to be helpful. Thanks for the support.
Half way thru it. I will deffinelty watch it again thank you
Always keep learning from your vehicle, believe me, over the road, payoff to the driver/owner to know the little things.
Thank you very much for the clear explanation.
No problem. Thanks for watching the video.
Thanks for the video brother, it was very good!!

thanks a lot
One of our truck kept throwing the code 520372/16
Truck is 2019 cascadia, 350k miles , we clean def filterand dpf, changed both inlet and outlet nox sensor, Doc outlet temp sensor, but code still show up after a week. Do you happen to know the problem?
Been taking to the dealer still the same thing, they clear the code and pass the SCR test and still show up after 2500-3k miles. My driver is OtR
I changed everything once..... With a straight pipe.
I have this one box DPF. This is my problem....
I have coolant leaking out of the bottom of the one box pan out of what looks like a drain hole. Even when the truck isn’t running it is leaking coolant. I am pretty sure coolant doesn’t go towards any of this whole system right?
Would the coolant be leaking by the DEF pump? And draining through to the DPF? It is a pretty steady leak and will drain the whole coolant resivoir.
There is a possibility that your truck DEF quality sensor, it is broken and the coolant is flowing to the DEF. The quality sensor is the one on top of the DEF tank. So, open the filler blue cap and with long thin stick check the color, if you see is clear your DEF is fine. But if it’s color is red, that might be the issue with ATS one box. I hope this help thanks for watching and support the channel.
I got a ATS Electric System Problem , but I cleaned the DPF filters 50.000 miles ago and nox sensor, maybe know what the problem is ?
How can you tell if the DOC or SCR are bad if you can't see anything physically wrong? I just replaced a box and after the old one was pulled they said the wiring harness was melted and several sensors were failed. What I want to know is if I can rebuild the one box with new filters and sensors.
It is possible to repair the ATD box, but I would not recommend to fix it, in our fleet we tried three times, and after sometime (around 6 months) those failed again. Perhaps if you can replace the DOC and SCR themselves that could work but that requires more money, I think. So, I think the best if to give back to the dealership for a core refund because once you altered the box they would not accept it. Thank you for watching the video.
I’m getting SCR NOX EFFICIENCY LOW CODE. Freightliner basically told me to replace my one box because the inlet Nox temp is lower than the outlet and all of the sensors and everything else is working fine. Can the DOC AND SCR BE CHANGED OR FIXED Without having to replace the whole box
This is a good question, there are some places that could fix your DOC box, but I would not recommend it because we tried in our fleet couple times it works for like a month and then the same problem comes back again, so at the end is a waste of money, perhaps you should wait to get some money and get a new one. This is just my personal opinion.
How does the inside of scr catalyst look. I know that is is a chemical reaction but how does it look in the inside of this chamber. Thank you
If I can get a photo I will post it for you here, but as you know how it looks the DOC, they are similar in design (honeycomb style)but the material from which are made from it is different I believe, I will investigate it and post a photo soon for you.
Did you find out what type of material scr catalyst is made off. Are a picture thank you
The design looks like the DOC but obviously the materials are different, sorry I could not open one yet, but I will try to get the photo of that. I am been busy doing other videos but this still on my list of pending material to know and share. Thanks for stay tune.
looks just like the filters
Im buying a used doc box how I can tell if is a good one with out remove the dpf filters?
This is really hard to tell if an used ATS Box will be fine, but there are couple things you could check:
1. Pay attention to the sides of the box, I have seen when DOC has been pushed, they cut around right side area (if you are seeing the box from the front side). This means it has been fixed.
2. Get something like a needle around 5 inches long, look for the DOC outlet Temperature hole, then insert the needle inside of the hole, if the box is Ok, it should go smoothly in, but if it doesn't, this means DOC is damaged and pushed.
3. Look at the the outlet of the ATS box, with a flashlight you can see if there is any crack at the end of the SCR, of course, this is just a small glance but it worth to check it out.
Remember even if all this points are Ok, the real test is to pass the NOx conversion process. I hope this help you and thanks for watching.
I have western star with dd16 one box after treatment system I cleaned the filters recently but my truck require me a force regen pretty much every other day. What could be the problem? And I found this video helpful. Thanks
It depends what you mean with “every other day”... if your truck is asking for it every week, that is Ok. If your truck is asking for it every day that means there is a problem. Usually, local drivers and long haul driver have different timers in their trucks for regeneration. In other words, the basic you can check is:
1. Are you a long haul or local driver? Local driver means a lot of idle which kicks in faster the parked regeneration than the one in a highway for long periods of time.
2. Is the time for asking parked regeneration normal? Compare the time before and now for the request parked regeneration. Is the same time? I mean by days.(even every three days is fine as long It passes the regeneration).
3. If your answer in question 1 is you are long haul driver and question 2 is every day. Then means... yeah, you might have an issue with your DPF or other exhaust components.
Try a good fuel treatment, I use Doc’s 1oz per 25 gal my DEF usage went up to 270 mpg and it never regens.
Thanks for the vid. Would you happen to have the thread sizes for chasing threads for all the sensors?
Hi, I have a 2016 cascadia dd13. The last parked regent it had black or blue smoke coming from the side and top. What might this be. Thank you in advance.
It might be burning oil or an injector misfire. For those kind of issues, my recommendation is take your tractor to your personal mechanic or technician and let them to a proper diagnostic. Thanks for watching and the support to the channel.
Everything is clear! Thank you Bro!
Bro is dpf filter same for cascadia 125 2017 with DD15 and Cascadia 126 2018 DD15?
I think they are the same DPF for those years, starting 2020 or 2021 those have been change for smaller DPFs. Check my video about the newest design on my channel.
Tengo un freigliner cascadia 2015 .
Cuando hago el regeration p cuando pongo el freno de motor o acelero mucho hay un ruido en la caja de los filtros usted tiene una idea de que pueda ser sera los Clams q se danaron o puede ser algo con los filtros.
No se si dejarlo asi a quitar losnfiltros .
Por desgracia ese problema es muy común en la caja de los camiones freightliner, en mi opinión personal, tendría que reemplazar toda la caja. Pero antes de ello le aconsejó que la examine un mecánico de su confianza que revise todo alrededor de la caja para ver si algo está flojo. Si todo se ve bien, si única opción sería reemplazarla. Esta es mi opinión personal, recuerde que su vehículo debe ser inspeccionado por un mecánico o técnico especializado en sistemas de emisiones antes de cualquier reparación. Muchas gracias por el apoyo al canal y espero que mi respuesta le ayude.
This guys hilarious… but very good video!?
What would be the “safer way” to eliminate the DPF system? I know is not legal
So you saying from 2012-2019 The DPF filter and the whole DPF unit with the DOC are the same size right
Yes, pretty much, few sensors are gone in the newest design but the overall box is the same size. Thanks for watching the video.
Bro i have a 2015 cascadia dd15 when i region very bad sound in the ats one box i dont no what hapen i change turbo charged diesel doser def doser both knox sensor diesel nozel but they still same sound when i drive one speed very good drive but when i press race pedal they sound very bad
Code came on spn 102 fmi 18
If a sound it’s coming from After treatment device (box), I am afraid that you will have to replace the whole unit. Please take your truck to a proper repair shop, so they can do the diagnostic to tell you exactly the problem, also to prevent further damage to your vehicle.
I have to re-tap the thread on the temp sensor hole, anyone know the correct tap size thread count I need?
Hey buddy this was an amazing video. I have a question please. I changed every single sensor you mentioned and also changed the metering unit plus the DPF (Filters) but my problem is not going away. I keep getting same codes even after changing every single thing. Would you please be able to help me with that or give me some of your great advice.
The codes I’m getting
SPN 5246 FMI 0
SPN 4364 FMI 18
SPN 3364 FMI 2
SPN 5246 FMI 15
SPN 5246 FMI 16
These are the codes I keep getting even after changing every single thing. I also installed the DEF Awning. Please take time to give me advice. Your help is much appreciated. Look forward in hearing from you soon. Thank you…
Hi I have it also until now no one fix it
one box is bad need new one at dealer $ 12000
Hi, sorry to ask now, been a year.
Did you run an efficiency test then regen after parts been replaced?
How’s it running now?
Hey Buddy, I just got replaced Def filters and Knox sensor from the freightliner dealership. My truck worked well for couple weeks maybe 2. One day, I was pulling 45k and going uphill in Pennsylvania and my def light started blinking even though I had full def and fuel in the tanks with 2 check engine amber lights came on. I then immediately pulled over on the side of the shoulder and view the fault codes. One was telling me poor def quality and the other one was SPN4364 FMI18 and SPN3364FMI2. I did parked regen on my 2015 Cascadia and the codes disappeared along with the engine lights. This only occurred when I'm heavy and going uphill. Can you please help me out with this situation.
It might be time to replace your ATS box or perhaps other components from the exhaust system are starting to misfire. If your truck still pass the parked regeneration every time you do it, just keep it that way. In the meantime, prepare yourself to invest some money in your vehicle. I hope this help you. Remember, you can ask the dealership if your truck qualifies for an ATS box warranty, I read comments around here that they have warranty, but it is something only the dealer can let you know.
Thankyou for your response brother. You've got a great knowledge and experience.
I had the same problem ats box is one that u need to replace it’s around 10 k and one year warranty
Thats a junk of money. These dealership are ripping customers off with their one box shi*. Its so expensive. My truck only have around 490k and I'm experiencing these problems. Smh
I know brother 10k is if u have new filters and new nox sensors and new metering unit other wise its 13 to 15 k and its a stupid system if u bypass it most likely U will blow ur motor
How do you know when you need a one box replacement?
The most common cause to replace your ATD (Aftertreatment Device) or One Box.
1. Diesel Oxidation Catalyst (DOC) has been push. This one is the most know by Technicians. Because the high back pressure generate by the obstruction of the soot or ash particles.
2. The Selective Catalyst Reduction (SCR) failure to pass the NOx conversion test. For this there are various issues like DEF contamination, SCR defective from factory, SCR crack from inside and many others issues.
These two are the most common reasons to replace your one box, other (less common) could be like Turbocharger failure and causing a moderate amount of oil to go into the one box.
I hope this help you to understand better when you need to replace your ATD. Thanks for watching and stay around for more.
Law sue them
We need to stop running 🏃♂️ hauling these heavy loads..
Do you mind if I share your content to a group page for truck drivers?
That will be greatly appreciate it. Thanks for watching and support the channel. Feel free to share my content with other truck drivers.
At the end isn’t it the outlet Knox sensor? At the back ?
Yeah, it is the Outlet Nox Sensor and yes, it is at the back of the box.
I have a 2016 Freightliner, I bought it about 60 days ago and it has spent 20 days total in the shop due to a reoccurring problem with ats. Nox sensors have been replaced, a thermocouple has been replaced and it still derates about once a week to 5 mph. It keeps saying bad DEF among other atd codes. OMG this is driving me nuts. If you're in Cali, I would love to stop by.
There are couple things you can check:
1. Make sure there is not contamination in the DEF tank.
2. Check the noise from the box when you are driving or active regeneration is taken place, rough noise around the ATS box can be a signal that it is getting bad.
3. Pay attention to DEF level, is it consuming too much? Or nothing at all? Those are signs that might be an issue with the DEF pump or injector.
4. Get a closer look to the stack pipe or the lower exhaust pipe, is there a black smog color around the outlet? If yes, that means one or both DPF might be bad and you might need to replace them soon.
I hope this help you and thanks for watching, I am glad to be helpful.
Sue freddlinners for bad de
All equipment should be warranty for life of vehicle
Turns out the box needed to be replaced, all is better now. It was replaced at the dealership they never mentioned a lifetime warranty.
@@gillisgil8972 interesting
Do you have all the OE numbers for the sensors?
Unfortunately, VIN truck number is required to be sure you are buying the right sensors, however, you could compare the old number with the new ones, pay attention to the plastic connector, if you look carefully, you will find the number of each sensor around there, including NOx sensor, sometimes they update the numbers, it might not match but if the sensor connector goes in properly, that is going to be the right one. I hope this help you, thanks for watching and support the channel.
Great content! Never seen anyone break it down as you did..
I had a question regarding my 1-box. I keep getting the "SCR Low NOx efficiency" code, but only when I'm under a load climbing hills, I've changed, outlet psi sensor, inlet/outlet DOC temp sensor, DPF temp sensor, both NOx sensor's, metering valve(2015 cascadia) and the code still came back on. It passes every regen, they last approximately 45 min. I have a new DEF pump at home and the #7 injector I'll change.
Now I heard you talk a little about the 1-box making noise, but what kind of noise? Like peices of metal chattering? I'm asking because I notice that when I'm driving a long a barrier I can hear like a clicking noise coming from that area. It's not a constant clicking, it'll click three time's, stops then repeat. Is that normal? As in, is that the quantity valve working and spraying? Engine miles are 681,300, ash count is at 55%, going to get them cleaned in two week's. I don't beat on my truck, I always go whatever state speed limit is and I don't ever go past 25psi of boost.
Glad you like the channel. About the ATS box noise, yeah, it sounds like metal chattering inside, you can heard it when you are driving or when your truck is doing parked regeneration. Pay attention to the sound when parked regeneration is taking place; it is a really distinct sound. Usually, that is a signal to replace to ATS box, might pass regeneration now, but eventually it will become more often. The ATS box might pass the SCR efficiency test barely, as well. To repair it could cost around $7000 just for the part, labor might vary. Of course, this is my humble opinion. Thanks for watching and stay tune for more.
Same happened to me got everything done what u did but i been told that i need to chenge the box part is around 7k and with everything it’s around 10 k I already spent 5 k this system is a joke
I appreciate the question you asked...Im having same issue, only when loaded ,and pulling hills..Then my Coolant temps go High, and Oil temp too..I have replaced so much, like Thermostat, water pump, sensors on One Box..Still pulling hills loaded, and i get all the Engine codes, and high temps..This morning a friend of mine who has a one box with only 200k miles is giving it to me..So hopefully by the end of today ill have an almost new 1 Box complete..I will try to come back here in a while and report if that solved my problem..Ive been battling this for over a year, and i cleaned the filters as well, problem still exists....Also i notice you say 25psi on Boost?...My DD15 will only go to 20psi, i wonder why that is??
I kept getting this, my harness was melted.
@@kt7r I'm glad that fixed your issue. Hopefully it permanently fixed it. If not read my recent response to Hookah B.
Were are you located??
I need to replace my dpf filters
Can you turn the box to the side and pressure wash the doc??
I do not know if it is going to work, I heard about high pressure air and even that, I will call that a temporary fix if your DOC is push already. If it is not push, it might work for more time as long your engine is running properly.
@@LetstalkDIESELwhats cause the doc to push out? from what you seen working on these trucks around how many miles the doc start to get push out.
@@jadb8452 it depends, usually more than 500,000 miles for sure. If you pay close attention to the exhaust for a moderate leak or you have the DDDL tool to check the pressure you can tell if it it push or not, other way around without tools it is to take out the DPF inlet pressure sensor, after loosening it, if it gives you hard time to pull it out it means DOC must be push, however this applies only for the front filter, not for the rear one. so your best shot it is to open both to be sure everything is fine. I hope this answer your questions.
@@LetstalkDIESEL thanks for the info
Bro is nox sencer attached to SCR or DPF ?
The Intel and Outlet NOx sensors, both holes are in the Aftertreatment Box. It is possible to fix both holes if they have been damaged in order to remove the old sensors.
When do I need to change my def box
The ATD (Aftertreatment Device) box should be replace for couple different reason like:
1. Turbo misfire causing oil going to the ATS.
2. Damage EGR cooler causing coolant to go into the exhaust system.
3. Bad fuel injectors.
4. ATD expose to Excessice smoke from the engine.
5. Not performing Parked regeneration when the vehicle need it.
This are just a few reasons why you MIGHT need to replace the ATD device, as always, you must seek first a proper repair shop to perform a complete diagnostic. Thanks for watching.
Is it important to change the actual one box too?
Yes, but this depends how bad it is the NOx efficiency, sometimes you could wait a bit longer to replace it, a technician with a DDDL software can tell you a more accurate estimate.
@@LetstalkDIESEL thank you!
Donde esta localisation
How long it takes to replace it?
Good question, it depends if everything goes smoothly and parts (everything new) are ready to installmaybe around 5 hours. Note: This time is for the whole installation which include harness with sensors installation, DPF installation, and cover. It might be even more time if transferring used parts from old to the new SCR.
@@LetstalkDIESEL my truck in the shop they said from 6 to 10 hrs but i think they working on many trucks aside of mine becoz it's been there for 3 days they said still working on it
Don’t you use the nox sensors as cores ?
Yes, we do use it as core.
What's up! How are you! I am following your videos and I see that you know a lot about DEF and DPF and I want to visit you for preventive service please send me your information thanks
Unfortunately, I do not own a shop. But if I open one in the future I will let know people around the channel. Thanks for the support and watching my videos. Stay around for more content to come.
Where are you located
Sir do you have link to regen the system
What do you mean with a "link" to regeneration the system? Do you mean if I have a video to how perform parked regeneration? Or something else?
I mean computer software to hook truck
Yes, we do have one computer to do force regeneration in our fleet.
Is one box repairable ?
This SCR box is NOT serviceable, so once it fails, you will need to buy a need one, trust me, we fixed one in our shop and it failed again after 6 months. So, try to get a new one or an used that is in condition (which is hard to find right now) thanks for watching and I hope this information is helpful to you.
Can u delete the def
You can delete the ATS device from the ECU/MCM, but your vehicle will not perform efficiently in a long run, you might not need to take care of the DPF/SCR but the trade of it is to deal with power/EGR issues and who knows what else after deleting the ATS device from the ECU/MCM. Personally, I do NOT recommend those kind of repairs but it is just my personal opinion. Thanks for watching.
You mean to tell me there's two dpf filter per one box
Yes, there are two DPFs that need to be clean per one ATS box.
They come with warranty ck out freddlinners or get a lawyer on it
12k for a box F that im cancelling that box if it goes out.
My truck smokes runs good has power just smokes
I change my oil at 25k.. my fuel filters at 12k….. u gotta baby these trucks… can run the oil as long as we use to… sucks
Law sue. Them for this
This thing is designed to fail, cost to replace is 15 to 18,000, and you will pay Freightliner this amount about three times in a million miles.
That is something Freightliner needs to figure it out, their newest truck has the same style box but with fewer sensors, let’s hope that improve reliability in the long run. Thanks for watching the video.
As long as it is a sealed unit it is unrepairable and they intended to soak the owners with the junk, this box is a gold mine for the right attorney and a massive class action
