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 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.”

“Man, this thing has been invaluable. Incalculably! From just being able to reset my codes to doing a forced regen, the investment has paid for itself 4 or 5 times over at least. I highly recommend it!”

“I had a light come on the dash. I followed the directions and the code went right away and stayed away. I forced a regen and it lasted 39 minutes. After all that I was like “that’s it?” Haha. Done. Knowing this device is going to be in my truck every run has given me a relief like no other. Buy one and I guarantee it will be a load off your shoulders. Awesome product. Sorry shop owners I don’t have time or money for ya.” 🤣😂💯
