APP FEATURES
Enhanced Fault Code Descriptions
Read Fault Codes. You’ll be provided with enhanced detailed fault code information.
For instance, you’ll see the following displayed:
SPN 5394 | FMI 3
- Aftertreatment diesel exhaust fluid (DEF) dosing valve
- Engine Controller
Detailed fault code information, will be provided such as description, troubleshooting, symptoms and possible fixes.
Fault Code Commands
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. To get rid of ghost codes, all you have to do is reset the fault codes with OTR Diagnostics.
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 clear fault codes with the OTR Diagnostics and clears the DTCs once. Note that if the fault code comes back a second time, you do need to take the matter seriously.
Aftertreatment Commands
Forced DPF regen. A forced DPF regen is performed when a diagnostic scan tool, such as the OTR Diagnostics, 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.
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.
Fault code history and command history
Quickly reference recent fault codes, how often they occurred and date stamp when they first occurred.
View commands with status history for how long forced DPF regen lasted, clearing fault codes and reset aftertreatment status.
Display Parameters
Live data is information that gets updated in real-time. This includes vital information about your engine and your aftertreatment system. The live data fields will be updated in real-time through the Bluetooth connection.
Why is live data important? Live data is an important feature that can help solve an intermittent issue or it can be used to get more information from your aftertreatment system during a DPF regeneration.
Some of the parameters you can track with OTR diagnostics include
- DEF Fluid Level
- DPF Soot Level
- EGR Value Position
- Aftertreatment Exhaust Temps
- Battery Voltage
- Boost Pressure
- Accelerator Pedal Position
- Engine Fuel Delivery Pressure
- + many more

OTR Performance® Inc.
Thank you for the kind words we really appreciate it, We did want to ask why you left a 1 star if you enjoyed the tool?
United StatesGreat so far
We are definitely using it it’s been test so far
United StatesHas already paid for its self
It's a great experience so far. Only thing I wish it showed the SOOT LEVEL and it would let me put in all my truck info. My friend has already purchased hers as well
USGreat customer service
It works great… for what it does. The customer service was excellent. I used it a couple times to force a regen and look at some codes. Sadly, it doesn’t do what I need it to do so it’s just a paperweight in my toolbox.
USSave me $$$$
Red light came on and truck went in Derate Mode. I connect the device and clear all the code. I went to shop and get the sensor changed. Saved me Tow :dollar:
USNice products and easy to
Nice products and easy to use 5 stars
USBest tool every had
This tool help you get closest dealer or repair shop
Overwhelmingly underestimated
When I was signing up for a year subscription and thought it would save my butt, I drastically underestimated the benefits of this service. I rarely wright a reviews, but I feel like i owe it to this guys. In the modern truck world, where regs, emissions, dealerships, brokers, feds everything is designed/working to drive little guys out of business/rip you off for every penny, nice to realize that there is an app in your phone that can help you get going/diagnose your truck at the dealer level. And probably half of everything is that they not outsourcing customer support to a 3rd world company. I mean I can't remember when last time I had a call answered by someone not only understanding English from a first try but actually knowing his ****.
Best tool!!!
