Modern trucks are complicated
Most drivers don’t like modern truck technology, but the tech doesn’t have to rule you. OTR Diagnostics will put you back in control of your truck. Truckers say the OTR Diagnostics is “super-easy to use” and “saved me thousands!” Our customers are as loyal to us as we are to them.
“This product is awesome! I didn’t need to know how to use it, it told me what to do! It’s the interface, man, if that’s the right word? It’s dumbing it down to a guy who really has no interest or clue about modern technology or trucks.”

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.”

Just imagine being able to get to a shop after you disable the derate that has you stuck on the shoulder of the highway, needing a tow for thousands. That alone saves you BIG.

Heavily Satisfied!
I have a 2016 Tiffin allegro bus motorhome with a Cummins 450 hp I SL9 engine in it. The engine only has 30,000 miles, but I had a few check engine lights that came on and that was the reason that I ordered the OTR OBD1 reader. I performed a scan and was able to find out what the problems were. I was able to change out a few sensors and correct the problem. After driving the motorhome again, another light came on indicating there was an additional problem. I ran a scan again, and the scan informed me there was a leak in the intake system. This was not a repair. I was able to perform so I took it to the nearest Cummins dealer. The Cummins technician performed an DIAG and informed me he would need to remove the entire exhaust system to find out what the problem was. I informed the tech that I ran a scan and there was a problem with the intake, not the exhaust. Had I taken my motorhome to the dealer and not known ahead of time what the problem was, I would’ve been out close to $7500 without ever correcting the problem. Thank you so much OTR for your awesome technology. It saved me so much money on the front end. FYI, after a diagnostic from Cummins and the repair of the intake, my bill was $1000 and the exhaust was never removed. Thank you guys again so much!

Great product
The product is great. Dealing with OTR is great. However I have an Android phone and I'm not sure yet about the new app. I have two Paccar motors and I'm not seeing a lot of the oem "P" codes identified on the new app like I did on the old one.
