Our plug-and-play tool gives you the power to run advanced diagnostic functions, including a forced DPF regen, in less than 5 minutes.

The Diagnostic Trouble Code + Aftertreatment system (OTR Reset) Tool is an advanced automated diagnostic tool that makes it quick and easy to understand what’s taken your truck off the road. 

Our patent-pending algorithm means that as soon as you plug in the tool, it immediately starts working. No special diagnostic software, hardware, or button-mashing needed.

You’ll have the power to clear fault codes, reset the aftertreatment system by reprogramming all the parameters to default values, and if necessary, perform a forced DPF regen of the DPF. Anywhere, anytime.

  • Reset Active Fault Codes. Fault codes that determine that there is an existing issue. Certain active fault codes can be cleared, however, if the problem has not been fixed the fault code will reappear prompting you to seek service.
  • Reset Inactive Fault Codes. Fault codes that indicate that there was a previous issue.
  • Clear first-time ‘Ghost’ Codes. What’s a ghost code? Specific trucks will display fault codes on the dashboard, and most of the time you’ll have a check engine light or a check module message. After this, a screen will appear stating that the error has occurred. Many of the codes that appear on your dashboard fall into the category of “ghost” codes, meaning that the fault code was triggered by certain conditions that are nearly impossible to recreate.
    To get rid of ghost codes, all you have to do is plug the OTR Reset Tool into the diagnostic connection and clear the DTCs once.
    Note that if the fault code comes back a second time, you do need to take the matter seriously.
  • Reset Ash Accumulators. Ash accumulators have stored values in the engine control module (ECM).  Ash level includes measurement of ash in the DPF.
  • Reset DPF Accumulators. DPF accumulators have stored values in the engine control module (ECM). DPF level includes measurement of soot in the DPF. 
  • Reset Aftertreament Learned Data. Measurement of learned data based on various engine components to adjust your injection timing based on characteristics of your engine sensor values.
  • Reset DPF Regeneration Timers. Measurement of time since the last DPF regen occurred. The calculation is based on time, miles driven, and fuel usage.

When a failure occurs, this will prompt you a “high soot” notification on your dash and will derate your vehicle to seek service. You’d need to take the filter off the vehicle and send it to an approved DPF cleaning shop so they can assess how badly it’s clogged. If the filter is a good candidate for cleaning, then you’d perform that service and reinstall the filter on your vehicle. 

This is where the reset tool comes in handy — because your filter is clean, but your engine controllers don’t know it yet! The OTR Reset Tool resets the system so your engine knows it’s operating with a cleaned filter.


A forced DPF regen is performed when a diagnostic scan tool, such as the OTR Reset Tool, starts the regen process. The DPF soot load could be too high for a passive or active regen to occur, meaning you’ll need to perform a forced DPF regen. 

  • When to start a forced DPF regen
    • When the soot level is too high for a passive or active regen to occur
    • When maintenance items are replaced on the aftertreatment system in order for you to clear certain fault code
    • To keep your DPF filters clean, which can save you fuel mileage and prevent breakdowns
Who’s the OTR Reset Tool for?

The OTR Reset Tool is for fleet owners, owner-operators and drivers who are tired of paying every month for check engine lights, regens, and resets. 

With this tool, you’ll instantly be able to:

  • Cut down on the days your vehicles spend in repair shops
  • Get a deeper insight into your engine’s performance and each rig’s unique quirks
  • Drive confidently at night or out of state with less worrying about getting stuck

If you’ve ever lost a day (or a load) due to breakdowns, engine faults, soot level, or mysterious, un-re-creatable ghost codes, you need this tool.

"Great tool. Glad I spent the money, it does exactly what they said it would. Already paid for itself in a couple of weeks just with savings of not having to pay someone to do a forced regen."

  5. Start Forced Regen - Regen will start after 30 seconds.
  6. The truck will increase RPM to higher idle 1000+ RPM to increase temps to burn the soot out of the DPF filter.
  7. The RPM will stay high until the truck finishes regen. ~20-60min
    *NOTE: Do not touch the accelerator, brake pedal, or clutch during this process or it will cancel regen.
  8. If regen does not start then you may not have met all conditions in order for the truck to start regen. Check for fault codes and try again. 
  9. Reset tool will remain plugged in until the regen finishes. After the regen has finished, disconnect the OTR reset tool.

"This device has truly been worth the money! I’m averaging one fault every other month, and this device clears the fault every time. Also, I’m regenning whenever I like"

  1. This product will not bypass the operation of any emission control component. This tool is used solely to reset the modules after replacing aftertreatment components or initiating a forced regeneration.
  2. You can use your display to find out what the fault codes mean, however, some heavy-duty trucks will not allow you to view your fault codes. In such a case you will need to plug into a diagnostic software to read the DTC.
