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

Great Product
Love knowing the codes before I go to the shop. A big advantage when talking about needed repairs. Clearing that ****** lane departure code is worth the money itself.
United StatesEasy setup works great. A must have if you want to do your own repair.
United StatesConnecting
It was very helpful and useful
United StatesDD15
It works very well. I solved the problem for $82.00. A temp senser and a thread chaser. That made me happy
United StatesPays for itself!
I recently had an issue with my abs light in the truck. Took it to dealership spent 1200 to fix. 3-4 months later the lights were back! Took to another shop, said it was a 2k $ piece I needed but it was on back order. So I got otr tool diagnosed it my self. Recommend items to check was the part the dealer replaced! I unplugged it, cleaned it, put silicone grease on it…. Problem solved!!!! No money spent!!
United StatesHandy tool to have
I’m only a month into my purchase but so far it’s hooked especially when you are having a constant dpf issue. Would like the option of seeing soot levels or even being able to do my own scr test
United StatesAmazing
Couldn't be happier
United StatesOwner
Well I have only used it once so far and I will say that I like it so far
United StatesAwesome
I an owner operator so much have worry about engine light. But if you have this device, that will peace of mine. I was engine light before and straight away repair that save money a lot and time. I recommend this device.
United StatesIt is good to do force regen.
It is good software to read codes and codes descriptions and do force regen It doesn’t delete active codes unless the issue of the code is resolved They need to upgrade the Bluetooth from 4.2 to 5.2 Thanks
United StatesPerfect!
Took me a second to get it connected properly. Also found that I needed to unpair it right after, or I had trouble reconnecting the unit later on. BUT, since I have found its quirks, I have worked around them and the unit does exactly what I need it to! It has already paid for itself. I do my own forced regens and clear/view codes. It has saved me from lockouts and unnecessary towing due to DEF system issues. Well worth the money!!!!
United StatesTokeman
So far everything is working good, it diagnose everything it's saves you money every owner operator should have one
United StatesFreightliner who !!!!!!!!
I’m so glad I made the investment, it’s so much better then goin to freightliner to get codes checked or other shops, just so they can do a regen and send me on my way, saving a lot of money and time now, thanks otr
United StatesWish there was more
I’m happy to have an alternative to sending my truck to shop but I wish I could have more access to adjusting settings in CCU
United StatesPure genius.
I live in Macomb, where this item is shipped. I got it overnight and it came faster then expected. I wonder if pickup is an option since im down the street. Worked perfectly. Got my truck running and hauling.
