About
OTR Garage Tools
At OTR Garage Tools, we believe diesel diagnostics should be simple, fast, and accessible — without relying on a dealership. That’s why we design easy-to-use diagnostic and reset tools that empower truck owners, fleet managers, and mechanics to take control of their vehicles.
We’re a team of technicians and diesel enthusiasts who understand how costly downtime can be. Our tools are built to solve real-world problems: clearing codes, triggering regens, and resetting SCR systems — all without the learning curve or expensive subscriptions.
