DPF Forced Regen Tools - What works and What does not

[Rich W.]

Another little update:

I tried to start a regen again today with the Diesel Decoder and got tired of waiting for it to initiate and gave up, although I only gave it about five minutes. Also looking through the live data it has a field for DPF soot load regen threshold and the value was something like 2.05%, and my DPF soot load is reading 0%. So maybe thats why. Didn’t have time to talk to their tech folks.

I then plugged in the DL handheld, and it initiated a regen immediately. So at this point the Handheld is the only device Ive tried that I will recommend, because it initiates regens immediately and reliably, and also has a field for the after-treatment injector activation. You know when it turns on and can watch the after-treatment temp rise. This gives me complete confidence in the device.

I’m no longer an advocate of the Diesel Decoder, other than for the fact that it gives comprehensive live data, clears codes, is easy to use, and is cheap. For regens, even though the tech guy said it should work, and it did for me once, it isn’t immediate, and I’m not convinced that you can do a regen at any time.

Hope this helps.

Does the handheld clear codes?

@FLSteve I don't know for certain that it will work with the epa22 engines, but assume an update will be made available if it doesn't.

I bought direct from the company so that I was guaranteed support. Some companies have differing policies for Amazon purchases, and I didn't want to risk it. Cost $70 more for that peace of mind.

Cursor over to the HDOBD screen and it takes you to code clearing. It will clear codes on anything with OBD and they routinely have firmware updates you can download and install.

Got my Diesel Laptops Handheld tool today, two days early, ordered from Amazon. Shipped from Diesel Laptops direct to me and of course fully supported by them. I probably won't touch this until next stop, Santa Fe, but we'll see if curiosity gets the best of me between now and Sunday.

I bet a dollar you won’t wait.

X2! Also curious if your manual has instructions for regen. Mine didnt but its intuitive enough for me to manage. But it seems like they would at least mention it in the manual.

I will let you know when I open the box. A few other tasks ahead of it for now.

I opened the box and retrieved the manual, nothing about regens. I placed manual back in the box and left it alone. A dollar is on the line!

Received the Diesel handheld unit and giving it a try. It showed soot level normal. My screen matched Rich W's screens. Regen in progress temperature went up to 1052.024 degrees. Will let it run until it says complete.

I have mine on my desk to check for updates before first use. Looks like Windows is required for the update tool, not sure if they have a mac version.

Yesterday when talking to CS I asked about updates. He never said there were any but did say it would require a "Product update tool" and its windows based. I told him I don't have windows he replied maybe you can borrow one... I'm not a real savvy
computer person.

I updated mine, not sure it's needed as obviously the coach is several years old but why not. I did not need to deal with the register code like the video showed. Installed the updater in Windows, ran it and downloaded the updates, one was an Aug 2022 file, several were May 2022, not knowing what these individual versions were on the device so who knows if needed or not. Boot remained at 1.0.5, displays version updated to 1.0.6, others remained the same. Once putting the SD card back in the device and powering it on again it offered to upgrade and I answered yes and it completed. Will not use device probably until Monday unless I need it for triage. I initially didn't see that they did include the USB cable with the device so I hunted for one with that plug and couldn't find one. Fortunately I did end up seeing they did include the USB cable needed as advertised.

DPF regen completed 1 hr 20 minutes. After cool down I now have the amber engine emblem light. None prior to regen. SPN 5862 Aftertreatment 1 SCR intermediate temperature. Status Active FMI=3 . I think this will clear after several engine starts, but not sure.

 

[Neal]

It may be the warning light that it's "hot back there" and to be careful where you park (leaves, dry grass, etc.). Can you share a pic of the dash with the light so we can see which one? I think it's also wise to leave the engine running during cool down until cool. The tech did with mine.

 

[stang37]

I let the engine run after the regen light went off probably and additional 30 minutes.

That’s definitely the High Exhaust System Temp lamp. You’re good.

I'm guessing it will clear on it own after a few starts or should I try to clear the code. I didn't see this code in the library on the Diesel handheld laptop.

 

[Neal]

What do you see when you start the engine now? Are all lights out?

The last time I checked a couple hours after regen (3PM central) it was still on. Doesn't matter if you start the engine or not. I'll check again in an hour or so. 7pm it will be about 6 hours after regen

 

[Neal]

What gets my attention is the time it took for your regen, that to me means your soot level was higher than "normal" and it's good you did the regen. Maybe try another regen? Mine took two. We really need to get better numbers on soot level, maybe @Rich W. can work with Diesel Laptops to get that in an update???
