Take me to "REGENERATION " School...Please !

[SargeDiesel]

I have read a few post about the Regen on the diesel... but my forum search skills seem to be lacking, I can never find what I am looking for... so help is appreciated.

I have approximately 5,500 miles on my 22 JTRD. This is the first time I have ever had this happen, so it spooked me a little.

I wasn't sure if I could turn off the engine or in what manner to continue to drive in. I received the notification when reaching my destination.

Why does this happen ? What triggers the system ? What is the purpose ?
Why do some go into limp mode ?
Am I supposed to do something to keep this from happening or is there something I need to do inorder to maintain the system ?

Im really just trying to get the five "W's" about the regeneration cycle for the JTD and the proper way to handle it.

I appreciate the input ! Thanks

You will get that notice after multiple aborted, i.e. not fully completed, active regenerations. The active regen entails fuel getting injected into the aftertreatment process to more rapidly burn out the collected soot matter. In my experience this happens when you hit 85% on DPF saturation or so many miles (for me around 800-1,000) since the last one occurred. If you regularly get steady speed highway miles (above 70 mph works best in my experience) in your travels you will have less active regens as passive will keep you well below the 85% threshold.

I would start by getting a monitoring device, multiple threads here on options for monitoring, so at least you can view the status of your DPF and regen cycles. Might seem like an annoyance but knowledge is power. I had the same warning pop up early in my ownership but haven’t had it since I started regularly monitoring and managing the situation. With a monitoring device and minor adjustments to your routine you will likely be able to avoid it as well.

When you say "Aborted" or "incomplete active regenerations" does that mean they are automatically happening behind the scenes without any warning lights or notifications popping up on tbe dash ?
I have never seen any other messages / notifications regarding this and I have never interrupted a regeneration cycle that I know of.

So this is a completely normal/as designed function of the diesel and you want it to happen ?

What would be the purpose of the "monitoring" device ? How would you use it to "manage" the situation ?

Time to dig in and research this... thanks for the input/suggestions.

Correct, there are no indicators built into the OEM display to indicate when or what type of regens are occurring. All of it is happening behind the scenes based on variables none of us know for certain. Not sure why they designed it this way, but IMO definitely not ideal for the operator not to know.

As such, the driver can turn off the engine in middle of it completing an active regen, i.e. while it is injecting fuel into the aftertreatment system. Obviously this is bad, so after a few failed attempts at completing a full active regen (which takes the DPF saturation below 8% from my observation) the warning message you saw will pop up to make sure you don’t shut it off again before it completes the regen.

You use a device to know DPF % and regen status so you don’t accidentally shut down in the middle of an active regen. For example, based on your DPF % maybe you decide to take the long way home via the interstate to get more passive regen time. Everyone’s situation and circumstances are different but with a modern diesel if you want to maximize the longevity of the engine and aftertreatment system, you need to consider these things.

Finally, a device can be as simple as a Bluetooth OBD2 adapter and app on your phone. Doesn’t have to be fancy or expensive and you don’t have to watch it all the time. After watching closely for a while I now have a sense for the impact of my normal trips on DPF% and only turn on the app on my phone every now and again to see status. Is it absolutely necessary? Probably not, but it keeps me from doing things detrimental to my ride out of pure ignorance which to me is worth more than the <$100 I spent on OBD2 adapter and app.

Thanks, you're explanation helps. I'm looking at the scangauge 2 and 3. I can get the vers #2 for $130 and the vers #3 for $250. Other than the fancy display and the ability to update the firmware via Wi-Fi, I don't believe there is a difference between the two. Im just trying to justify the cost of either.
So with an app, I guess you need a bluetooth adapter for the OBD2 port and an app for the cell phone... are you using android or ios ? If android, what adapter/app are you using and could you please provide some screen shots ?
I would think for the price, the stand alone scangauge 2 would be all I need... but I still want to learn more about the regeneration process and the available programers to monitor them.

Any of these will cause a regen. Filter percentage, time and mileage. I have seen filter % from 72% to 83%. Minutes from 670 to 980. Mileage from 700 to 900 miles. When it goes into regen. It will take around 13 minutes at highway speed to complete a regen.

 

[Badunit]

If you take frequent long highway trips you'll probably never run into this because it will passively regen as you drive and most active regens will have time to complete. The DPF doesn't like short trips. On my Ram, the only active regens I have ever seen are the ones that occur once every 24 hours of operation, like clockwork, whether needed or not. I have never had a "nearly full" message in 8 years of ownership as my daily driver.

I second the suggestion for getting a monitor. If I have to shut down my Ram before an active regen is done, I log it in my head that I can't run around town too much before taking a long drive to let it complete. Of course, you don't actually need a monitor. If you shut down (or sit at a stop light with the windows down) when an active regen is happening, it probably smells like something is burning. My Ram smells like burning rubber during an active regen. I assume the same is true for the Gladiator but I can't verify that.

The big smile you get from all that diesel torque overcomes minor issues such as this.

I use the OBDLink MX+ and Car Scanner Pro with iOS for my solution but I believe both work with android as well. The OBD tool is much more expensive now than when I bought it but you can use it with JSCAN or Alpha OBD as well to adjust tire size, add LED lights, etc. So it has some versatility as well and it has worked flawlessly for me. Pick what suits your appetite for tinkering, the more expensive options are more plug and play. Either way you won’t regret it, money well spent if you are planning to keep it for a awhile.

I wasn't sure if I could turn off the engine or in what manner to continue to drive in. I received the notification when reaching my destination.

I went through this for the first time last weekend. I'm at 2100 miles and mostly do short trips. I got on the highway cruising at or around 70mph, after 15mins the message changed from "continue driving" to "complete".
Pretty simple, just plan a trip on the highway or open road next time you get the message. It was approximately 12 mile trip to complete.

This is what I hate about today's diesels. Don't have a Jeep diesel, but have plenty of other tier 4 engines. Nothing worse than putting in a full day and wanting to quit, then getting the regen in progress don't turn off engine.

I preferred the scangauge 2 due to it's size. I stick mine on top of the rear view mirror.

Very interesting we have 6 3.0 eco diesel total 1 Ram and 4 Jl/Jt's and 1 Grand cherokee and have never seen that message? I wonder why? You would think at some point we would have we have a total of 500k on the bunch? My 6.7 Ram's give you message but not me eco's must be something in the computer system

Mind providing a picture ? Would bevnice to see exactly how it would look. Thanks

You must take longer trips... seems the 10 minute trips to the piggly wiggly is my culprit... lol seems short trips can't burn off the gasses, the DPF filter gets full, eco diesel tries to do a passive regen, you don't know this because it's in the background, after interrupting several attempts, you get the message for the active regeneration like I did...

Thats good information Thank you I've had it on my cummins but not on the ecodiesel yet........
