OTR Diagnostics is a powerful and user-friendly HD diagnostic tool designed to help you tackle regen problems, non-stop alerts, fault codes, and unexpected derates on your Heavy Duty Truck. Developed by OTR Performance Inc, this iPhone app provides you with a wealth of features to manage your vehicle's health on your own terms.

With OTR Diagnostics, you can access detailed insights on fault codes, monitor live data in real-time, and execute essential commands such as initiating a forced DPF regeneration. This modern HD diagnostic tool gives you the power to take control of your truck's repairs and maintenance, without relying solely on dealer technicians or roadside mechanics.

One of the standout features of OTR Diagnostics is its deep understanding of fault codes. It unlocks the mystery behind fault codes, providing you with valuable information about their origins and potential fixes. This level of detail rivals sophisticated dealership software, giving you the knowledge you need to determine necessary repairs or parts replacement.

Live data monitoring is another valuable feature offered by OTR Diagnostics. With real-time information on your truck's operations, you can keep an eye on parameters like DPF Fluid Level, EGR Valve Position, Boost Pressure, and more. This allows you to anticipate issues before they disrupt your operations, helping you maintain the health of your truck.

OTR Diagnostics also keeps track of your truck's historical data, logging fault codes and commands. This valuable information gives you insights into recurring issues, helping you identify patterns and find solutions.

Compatible with a wide range of truck models, including Cummins, Detroit Diesel, Paccar, Volvo, and Mack, OTR Diagnostics offers extensive coverage for your diagnostic needs.
