Pro Subscription and App Explained

OTR Diagnostics goes beyond your typical hand held scan tool.

detailed fault code information


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.

✔️ 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.

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!

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.

✔️ Reset Fault Codes
✔️ Reset Aftertreatment
✔️ Forced DPF regen

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.

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.”

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.”

Overall excellent product. It does crash often while watching Live Data, which only requires a reconnect, so minor yet annoying.

OTR subscription

Overall the product works well and as advertised. I don’t particularly like the subscription aspect of the service. Once I’ve paid for the product, our relationship should be over. Unless it is going to be regularly updated and have new features added, what’s the point, other than to continue selling me the same product over and over.

Excellent device

First I bought the reset tool and it makes any paccar engine do a regen regardless of codes or even if filter is clogged.Now the software saved me from going bankrupt due to going to paccar dealership where they charge thousands and rarely fixed the issue,Thanks for coming up with these 2 excellent devices.

Saved me getting towed twice!

I was able to diagnose a sensor on the filter, and replace it myself. Also appreciate the filter temp for climbing long hills.

It’s great…

then some genius thought it would be a good idea to update the user interface which made things more complicated and more difficult to use. Also it used to recommend solutions for trouble codes. Now it says the same thing the truck says. I won’t be giving it up though, I like being able to clear ghost codes and force regen myself!

Well worth it

If u own a late model truck u have to this. This will pay for itself after one use. Clears codes on paccar. I had a couple injectors go out on me hooked this thing up ran live data noticed the fuel psi really low and surges. Tons of info would highly recommend it.
