In less than 1 minute, handle DTC issues including...
  • 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.
Plus, overcome these aftertreatment issues in 3 minutes or less
  • Reset EGR Derates / DPF Derates. Accumulators. EGR / DPF derates have stored values in the engine control module and aftertreatment control module (ECM/ACM).  Reset the EGR / DPF derate is necessary to perform after replacement of engine or aftertreatment components.
  • Reset DEF / SCR Derates. DEF / SCR derates have stored values in the engine control module and aftertreatment control module (ECM/ACM).  Reset of the DEF derate is necessary to perform after replacement of aftertreatment components.
  • 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.
  • Reset DPF Soot Levels. DPF soot levels have stored values in the engine control module and aftertreatment control module (ECM/ACM).  DPF soot levels determine the status of your soot level in your DPF system. Reset of the DPF soot level is necessary to perform after replacement or cleaning of DOC/DPF filter.

How the OTR Reset Tool Helps with High Soot Notifications & Derates

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.

What’s a forced DPF regen, and when should you perform it?

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

Reset Tool FAQ

What does a forced regen do?

Forced regeneration is a diagnostic process that builds temperature to burn soot accumulation down to ash within the dpf filter. During this process, the truck's computer can closely monitor and test multiple portions of the after treatment system. This type of regeneration can only be performed when a diagnostic tool starts the process within the truck's computer.

What if the fault codes do not go away?

Yes, this can happen! If you have an existing issue or “Active Fault,” you must correct the issue or perform a DPF regen for the code to go inactive.

Will this fix my truck?

The OTR Reset Tool helps avoid problems, aid in resetting parameters, and running a forced regen. However, if you have any component failures related to the aftertreatment system, they will still require repair.

Will a forced regen void my warranty?

Resetting faults, resetting soot levels, and running forced regens will NOT void your warranty.

How often to do a forced regen?

A forced regen can be performed as often as possible. As a general rule of thumb, we recommend once every couple of weeks to ensure that the filters are maintained.

Works Perfectly

Had a hard code on my 2015 mx13 and it debated to 80% and the truck wouldn't do a regen. Bought this tool and it cleared everything and runs great. Great to be able to do a forced regen anytime I want now.

Every used truck needs one!

I have a used 2014 Kenworth T-680 12-speed with 959,422.9 miles on it and it had a DPF / Electronics problem whereby it wouldn’t properly recognize when a regen needed to occur while in motion at interstate speeds. Instead, I would get a suddenly surprise warning with a red flag stating to stop immediately and do a parked regen. If I did not pull over within 2 minutes, the truck would start counting down to shut off permanently. Even after service at a Kenworth for 2 weeks, with every excuse under the sun as to why they cant figure out ‘why’ this is occuring, They baked the DPF reinstalled it and sent me on my way. The problem still persisted. After forcing a regen with the OTR reset tool and clearing codes a couple of times, suddenly the truck started recognizing that an in-motion highway regen was needed and alerted me on the dash to pull over and do a parked regen. Now, after a couple more weeks of forced regens it alerts me with the proper message of DPF regen occuring, let cleaning cycle complete. Do not turn off engine. Also, I was getting a frequent Engine check light and Engine wrench check light, but no codes were recorded in memory as to why. Now this occurs less often, usually after taking a steep downhill with jake brake, or climbing a steep hill with max gross weights of 65k and above. I now have been doing forced regens and forced code resets 2 or 3 times per week, usually after a driving shift. The engine has been stronger now with more torque to pull hills and fuel mileage averages 5.4mpg @ 75 mph with 65k ++ or 7.5 mpg @ 75 mph at less than 60k. So 5 stars for this great must have invention that allows me to keep the system optimal and will also allow me to ‘Force Regen’ and ‘Force Reset’ codes when bigger issues may need a tow to the dealership shop 100 miles or more away. This way I can finish my load deliverys and arrive for service on my terms and not remain stuck at the mercy of an unexpected tow bill for this specific problem.
