Critical Data. Zero Downtime. No Service Required.

In the field, information is just as important as your wrenches. When a machine derates on a remote site or a truck is sidelined on a highway shoulder, you don’t have time to hunt through greasy binders or wait for a webpage to load on a weak signal.

FaultFlow is a curated collection of pertinent technical data designed specifically for Heavy-Duty Equipment Technicians (HDET), mobile mechanics, and fleet managers. We’ve consolidated the most vital troubleshooting information into one high-speed, offline-ready mobile resource.

Why FaultFlow?

• Verified Technical Specs: Access precise sensor voltages, resistance values (ohms), and pinout diagrams for Engine, Aftertreatment, and Powertrain systems.

• Built for OTR Machines: Deep-dive data focused on the brands that move the world—including CAT, Cummins, Detroit, and more.

• Beyond the Code: We don’t just show you a fault; we provide the pertinent wiring lead-ins and technical facts required to troubleshoot with confidence and eliminate "parts-cannon" guesswork.
