DPF Forced Regen Tools - What works and What does not

[Rich W.]

I should receive this in a couple days and will review it:

Diesel Laptops Handheld Heavy-Duty Scan Tool with Regen

The Diesel Handheld scanner is very simple to use. This handheld is specifically designed for the heavy-duty market. It allows reading and clearing of DTC's, Live data reading, and even DPF regens on most makes and models. This tool comes in a nice carry case and includes an OBDII cable as well...

They state it clears codes and initiates regens. I have no reason to believe there will be any problems with it. But they do not state that it performs the After-treatment Re-set as the OTR products do.

I’m not sure thats really an issue as most of us will never need to do that. I’ve never used that command; just cleared codes and performed forced re-gens. If some day I need to have my DPF baked, I would need the after-treatment re-set, but most folks would drop off their coach and have this done and it would include the re-set. This feature is more aimed at the trucking industry.

I just received a reply from Nexas support. Frankly, I am very impressed with how quickly they respond:

Here is the exact reply:


I did not meet condition 2 or 3. I have no idea if I met condition 4. I am going to ask for details on condition 4, as that would provide the data we are after


Update 10 minutes later:

The support tech is engaging in active support with me right now having me collect data. This is kind of impressive. I didn't even mention to them that there is a web forum discussion going on about their product.

Even if it does work, this would not be acceptable to me as I would not wait until my DPF was 80% plugged to perform a regen.

I also have this: https://www.diesellaptops.com/collections/handheld/products/used-diesel-decoder
and it is a fantastic code reader (uses phone or tablet) but does nothing else. They have a new version that does regens for $350 but I haven't tested it.

However if a less expensive device such as the Nexas unit works for you, this would be good to use in conjunction as it will tell you the % soot load in your DPF, and the total investment for both would be less than the Diesel Laptops handheld unit I referenced above.

Screen shot from the exhaustive list of items reported by the

Diesel Decoder (I think it covers every parameter monitored by the ECM):

I assumed this was an ecm issue. Based on your experience, do the other parameters regarding temp of coolant and scr matter with the tools you have used?

They wont prevent doing regens if thats what you mean, but regens should only be initiated at normal operating temp, so in that regard it temp matters. SCR data would be unrelated. Im not sure if I answered the question though…

I think you did.

My take away is that the nexas tool isn't going to be the tool I need. I Will wait for your pending review of the tool you ordered.

Thank you.

Sounds good and here’s a potentially worthwhile UPDATE:
The Diesel Decoder ($350 and uses your phone or tablet)….

Now Does DPF Regens!​

The Diesel Decoder is now updated to do DPF regens! To access these features, make sure you update your Diesel Decoder app to the latest version on the app store you use.

So I updated the app, the commands are there, but I was unable to get it to do a regen. It took the command, but the regen never started. I warmed it up to 186° so that wasn’t the problem, but maybe it wont do a regen if the DPF is at 0% soot load (which mine is). I’ll call them on Monday. If it works this will probably be the best bet for code reading and clearing and performing regens. So stay tuned for more on Monday….

Just a thought but perhaps Monday when you ask whether it will do a regen at 0% soot, you could ask if it can do a regen at any other soot level les than the 80% mentioned?

Good research and write up by you guys, thank you.
