Compare OTR Reset Tool vs OTR DiagnosticsIn 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.

- 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.

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 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

Magnificent tool
i am learning more each day about how wonderful this tool is.

Easy to use tool
We have 400 ISL Cummins RV. We purchased this tool to force a regen. We had to take our RV to diesel shop because our ECM needed to be updated. I believe this tool would have worked if we had been current or updated. We returned the tool to OTR and received a full refund. If I was on the road full time this tool would be a must have.


Kept me from being stranded in the middle of nowhere
Kept me from being stranded in the middle of nowhere The OTR reschedule was able to allow me to nurse my RV home so I could have it repaired on a timeline that better fit my budget and schedule rather than being forced to have it repaired just to get home. And also save me a $3000 tow bill.

Awesome
Easy to use and very good

Owner operator
Works just like you said it would.

nice
It worked just like it was advertised. I used it twice and it cleared all the problems. If you look at the shop bills it has already saved me. It has paid for itself many times over.

Owner
Excellent very good.

Cummins forced regen
Used it for the 1st time as a experiment trial on a forced regen, it worked exactly as described and very easy to operate. I plan to use it every few weeks as part of my maintenance plan, wished I would have bought it sooner as I could have used it on the road when I had regen troubles a couple months ago, thank you RK

Cummins Reset Tool Review
Excellent experience. Clear instructions on performing Regen without the need to take our 2012 Freightliner M10 to a dealer or Service location. Wish that I had know much earlier. I highly recommend for monthly maintenance.

Dependable
Outstanding I truly recommend this to any Truck Driver with a Cummins engine

OTR PERFORMANCE CUMMINS
