Our team connects directly to your truck’s onboard systems to pinpoint issues with accuracy and speed.
We don’t guess. We use data-driven diagnostics to find the root of the problem so you can avoid unnecessary repairs and downtime.
How Our Truck Repair Diagnostics Work
We use repair diagnostics to diagnose most heavy-duty makes and models, including CAT, Cummins, Detroit, International, Volvo, Mack, Paccar, Mercedes, Diamond Logic Builder, Allison, Meritor Wabco, and Bendix.
What Are Computer Diagnostics?
Computer diagnostics allow technicians to access your truck’s onboard systems and read real-time data from sensors throughout the vehicle. These systems monitor engine performance, transmission, emissions, and more.
When a problem occurs, your truck generates diagnostic trouble codes that help identify the exact issue. This allows us to troubleshoot faster and fix problems correctly the first time.
