OTR Diagnostics goes beyond your typical hand held scan tool.
VIEW FAULT CODES ON YOUR MOBILE DEVICE
OTR Diagnostics gives you access to vital information about fault codes, their causes and more. These details rival advanced dealership software, far exceeding your average handheld scan tool.
Once you know the problem you can take care of it. Who’s in control now?
This device has already paid for itself! It correctly said we needed a NOX sensor in order to get the check engine light off. 100% correct! Saved several trips to the dealer. 5 Stars!

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.
Didn’t we say you’ll feel like your in control?
Really enjoy how much information is offered with this tool and details how to fix the problem without a expensive bill at the end besides buying the parts .. For a owner operator you can’t go wrong with this tool trust me.

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 |
✔️ Battery Voltage |
✔️ DPF Soot Level |
✔️ Boost Pressure |
✔️ EGR Valve Position |
✔️ Accelerator Pedal Position |
✔️ Exhaust Temps |
✔️ Engine Fuel Delivery Pressure |
“Just got the otr tool today, hooked it up and couldn't be more pleased with how well it works and the real time data is a huge help when trying to diagnose.”

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 reset fault codes, reset aftertreatment, initiated forced DPF regens, and how long regen lasted.
“After $1800+ dealer dollars in a month, I went for OTR’s subscription because of the 60 day return and solved my issue in about 2 hours after the tool arrived. After clearing codes and a 90 minute regen … Issue fixed. Money well spent.”

Quick and easy to install on my phone and now there is a little peace of mind.

Very easy to use
Quick and easy to use

Great Product
Great Product for owner operators will help keep your trucks running smoothly and keeps shops from beating you because you’ll know what’s wrong going in!

My OTR tool
So for I love it . I did 2 force regen and while On my way to phoenix az from Houston Tx I had a check engine light twice I was able to pull over and reset both codes so that I could make my deliver

I stopped in a fuel island reset the truck and I was on my way with no D rate

Nice product
Nice Product I did use it a few times it did work well for me thank you

I was on the right track before receiving the tool. But I still didn’t find the problem with the reader. The clutch switch had fallen off and I kept listening to everyone else. But Peterbilt had 39 pages of codes, not one for an open switch for the clutch… I haven’t used it since. But plan on using it just yo get more of a feel of it.

Great tool to have
Everything has been going well

Otr diagnostic professional
From now just amazing good experience then I recommend otr diagnostic professionals if you have more than one truck and engine different you can use it on both engines tools very useful good day to all of you….

Paid for itself
I'm still getting use to it, however, it already paid for itself by not having to lose a day's work going to mechanic to reset.

Well worth the attempt
I had some issues come up with a freightliner step van with a cummins 6.7l engine. I spoke with a rep who was very nice and knowledgeable. He was straight forward that there were some codes on cummins that this wouldn't work for, but assured me that I would receive a refund if it didn't help. Super impressed with every phase. The sales, interface, tech support, and the return was as easy and pleasant as one could ask for. My issues were abit deeper unfortunately. I would have kept the tool and membership if the path forward wasn't so expensive to fix the truck. Thank you all at OTR!

Easy to install, gives me extra knowledge on truck and after treatment performance

Saving lots of money
The tool is very useful and saves you a lot of money

Great tool
The shop said they couldn't get the truck to regen. I hooked the OTR tool up and performed the forced regen. No more check engine light and the truck is running great again.

Nice unit
Looked good the app was nice didn’t get to use tho as I needed one for cat equipment
