APP FEATURES
Enhanced Fault Code Descriptions
Read Fault Codes. You’ll be provided with enhanced detail 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 occured and date stamp when it first occured.
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

United StatesA Must Have Device!
I found this product when researching buying a newer DEF equipped truck and I am so very thankful I found and purchased one. I have only run my newer truck for one month have forced regen twice and cleared up to 45 fault codes to keep on running. I realize I have some sensors that are needing replaced or another component of the system but without this device I would be devistated by buying this truck. Thanks a bunch OTR!
