About this app

OTR Diagnostics gives you access to detailed fault code information, monitor real-time live data, perform commands like initiating forced DPF regeneration, and track command and fault code history, all from your mobile device.

View Active / Inactive Fault Codes:
Access to vital information about fault codes, their causes and more. These details rival advanced dealership software, far exceeding your average handheld scan tool.

- Quickly discover what those dash lights mean.
- Know what caused the problem.
- Learn how often the problem has occurred.
- Know how to fix it or what components need replacing.

Send Commands:
Gone are the days when only your dealer technician or roadside mechanic could force a regen on your truck. You can also reset fault codes or aftertreatment. Send the command from your device in just one tap, and the process begins. Now you can perform your own repairs and maintain the DPF system yourself.

- Forced DPF regen
- Reset Aftertreatment derates and more!
- Reset Fault Codes

View Live Data:
Modern trucks have computers making thousands of decisions every second. OTR Diagnostics’ live data gives you real-time information the computer is using to run the truck. Do you want to monitor what kind of temperatures your exhaust is reaching during regeneration or what your EGR position is?

Live data is where you will find that and so much more. Viewing live data lets you see problems before they stop you in your tracks.

OTR Diagnostics lets you monitor things like:
- DPF Fluid Level
- DPF Soot Level
- EGR Valve Position
- Aftertreatment Exhaust Temps
- Boost Pressure
- Accelerator Pedal Position
- Engine Fuel Delivery Pressure

View History:
Puzzled with a reoccurring issue that’s not so easy to resolve? Knowing your history can help you diagnose the problem.

OTR Diagnostics records fault codes and commands. Now you’ll know where your truck had issues and when you cleared fault codes, reset aftertreatment, initiated forced DPF regens, and how long regen lasted.

Not worth the money. If you purchase the otr tool make sure you get the one without the subscription. The one with the sub is kinda pointless if you have guages in your truck. I bought it thinking that even when my sub ended it would still do what the one without a sub would but unfortunately it does less. My advice would be to buy the reset tool without a sub and just get a scan tool to read codes and you would be good to go.

Had problems with app driving me crazy, kept crashing. got a hold of customer support and they took care of it promptly. This is such an important tool to have in your tool box if you don't have this one I suggest as an owner op you own some kind of scan tool.

update: did get it working on my phone. It stopped working again when I updated the app, but a delete and re-install fixed it. Very happy with the app overall. Works great but not on my new phone. Have to steal my wife's phone to use. Just crashes when launching the app. Maybe because I have android 11?
