"I’ve been using this product for years. It has saved me from being towed and allowed me to properly diagnose issues without the dealership. It keeps track of fault codes and records all engine specs. But the best thing is it allows me to force regen to keep the engine running correctly."
-Keith Spalding
OTR DIAGNOSTICS
Your truck, your control!
Get a 1:1 match of what dealership software sees, including OEM P-Codes, and unlock detailed explanations of each fault code.
Understand not just the code, but the specific issue and suggested fixes.
Live data allows you to see and address issues as they happen, preventing minor problems from becoming major breakdowns.
With real-time data, you can diagnose issues with greater accuracy. No more guesswork.
With bi-directional commands, you’re no longer stuck waiting on a shop to handle what you can do yourself.
- Reset active and inactive fault codes
- Reset the entire aftertreatment system
- Reset derates that slow you down
- Reset soot levels
- Run forced DPF or SCR regens right from the cab
These commands put you back in control of your truck, keeping you on schedule and out of the waiting room.
History is helpful if you plan to share the fault codes with your shop, technician, or fleet manager.
It lets you show them exactly what’s wrong, keeping everyone honest and on the same page. This way, you can ensure your repairs are done right and on time.
