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 StatesGame changer!!
Well after receiving my OTR Diagnostic tool, it has already saved me $$$. Recently had a breakdown and the diagnostic tool told me the issue right away. Shop tried to convince me it was something else. Gave them fault code and they back pedaled quickly!! Their diagnosis was over $4 K!! Actual problem was only $1372!! Already paid for itself!!
United StatesA must for the owner operator
OTR already save me couple of trips to the dealership and glad I bought it.thanks OTR...

Works great so far, I haven't tried the forced regen yet, but I have used it to read codes and clear them, without having to go to a dealership and sit there and wait and pay for the privilege. Well worth the cost.

its very helping

United StatesGame changer
I learned so much about the emission system on these trucks
United StatesOTR DIAGNOSTIC TOOL MUST FOR OWNER OPERATORS
I have always had to go to a shop and then wait for hrs to get a mechanic to bring the laptop to connect to my truck computer to find out what the check engine code is and what was needed to fix the issue. I am capable to do most repairs myself but I didn't know what parts to fix the problem myself until the shop told you what is wrong but most likely they will not tell you exactly what is wrong without them looking at your truck and then they will tell you it's going to be a few day's before they can get you in the shop. You will probably be paying several hundreds of dollars for them to fix your problems and they will charge you for the computer hook up also. I just got this tool and had to use it the next day and I was able to see what the code was for and got the part same day and replaced the bad part in about 1 hour and then cleared the check engine code and it hasn't been back on since.. This is the best investment I've ever made and it saved me about half the cost on my first time using it. I'm very pleased with this product and would recommend it to anyone who is a owner operator.
United StatesSatisfy customer
Really satisfied easy to use and worth the money
