Superior diagnostics for your trucks

For the dedicated owner-operator, the fleet manager, or the hands-on technician ensuring peak uptime - OTR Diagnostics is game-changing.

So much more than a diagnostic tool

With OTR Diagnostics, think of it as the difference between skimming the surface and diving deep into the ocean's depths.

7 Reasons Why You Should Switch to OTR Diagnostics

Unlike the OTR Reset Tool, OTR Diagnostics empowers you with comprehensive diagnostic insights.

1. Multiple Vehicle

Get full diagnostic access to an unlimited number of vehicles with a variety of makes and engines.

2. Read and Reset Fault Codes

View/reset active and inactive fault codes. Detailed descriptions provide troubleshooting, history, and possible fixes.

3. Fault Code & Command History

Know how often and when a fault code was reset or a forced DPF regen lasted.

4. Reset Emission Derates

When you’ve replaced aftertreatment parts to comply with a derate, you can reset the aftertreatment values and be on your way.

5. Start a Forced DPF Regen

Perform a forced regen when you’re unable to initiate a passive or active regen due to a high soot load or other variables.

6. Live Data

Viewing live data keeps you informed about your vehicle at any moment. Data includes: DEF Fluid Level, DPF Soot Level, EGR Value Position, Aftertreatment Exhaust Temps, (+more).

7. Updatable to the latest years

Automatically updates with current engine types for a seamless compatibility.
