Description
OTR Diagnostics — Trusted by 10,000+ Truck Owners
Dealing with regen problems, nonstop alerts, fault codes, and unexpected derates on your heavy duty truck? You are not alone. More than 10,000 truck owners and fleets trust OTR Diagnostics to take control, cut downtime, and avoid expensive dealer visits.
Powered by OTR Assist + OTR LINK 2
This is more than a scan tool. OTR Assist is your AI partner, breaking down fault codes in plain language and helping you troubleshoot and decide if you can keep driving or need service now. Paired with OTR LINK 2, our proprietary Bluetooth adapter, you get faster connection speeds, more accurate fault code data, and more live data parameters than ever before. It is 5X better than previous hardware. Ask us how to get a FREE upgrade today.
Commands That Keep You Moving
With bi-directional commands built right into OTR Diagnostics, you are no longer stuck waiting on a shop to do what you can handle yourself.
Reset active and inactive fault codes
Reset the entire aftertreatment system
Reset derates that slow you down
Reset soot levels after a DPF service
Run forced DPF or SCR regens right from the cab
These commands put you back in control, saving you time, money, and downtime.
Fault Code Insights
Go beyond a flashing dash light. OTR Diagnostics helps you understand fault codes with the same level of detail as dealer software, but in plain language you can actually use.
Decode your dash lights
Uncover the root causes of issues
Track how often a problem occurs
Know which repairs or parts are needed
Live Data Monitoring
Want to know if your regen is working? Want to monitor exhaust temps, soot levels, or DEF? OTR Diagnostics lets you see your truck’s vitals in real time so you can spot issues before they stop you.
Common live data parameters include:
DPF fluid level
DPF soot level
EGR valve position
Aftertreatment exhaust temps
Boost pressure
Accelerator pedal position
Engine fuel delivery pressure
Available live data may vary depending on the engine model your device is connected to.
Explore Your History
Recurring problems? OTR Diagnostics logs every fault code and command so you can see when issues happened, when they were cleared, and how long regens lasted.
Proven. Tested. Backed by Support
We run OTR Diagnostics, OTR Assist, and OTR LINK 2 on our own fleet of test trucks including late model Paccar MX engines to make sure everything works before it reaches you. That is why more than 10,000 drivers already trust OTR Diagnostics.
Made in Michigan. Built for You
We engineer, assemble, and ship right from our shop in Macomb, MI. If you are nearby, stop in and see us.

Build 882554926v4.0.62026-02-18 16:03:04
Thank you for being part of the OTR community. This is one of our biggest updates yet.
NEW Volvo & Mack Exit Inducement Support
We've added exit inducement functionality for Volvo Trucks and Mack Trucks.
This feature supports 2014–2024 Volvo and Mack trucks equipped with Volvo or Mack engines.
If your truck is stuck in 5 MPH derate or inducement mode, you now have the opportunity to reduce the derate and get back on the road, potentially saving thousands in downtime, towing, and dealership costs.
This update puts more control in your hands and keeps your truck moving when it matters most.
We're committed to giving drivers and fleets the tools they need to take ownership of their trucks.
