ScanGauge for Heavy Diesel Trucks & Commercial Vehicles

Heavy diesel trucks, semi-trailers and buses use J1939 and J1708 diagnostic protocols — not the standard OBD2 found in passenger vehicles. The ScanGauge D and ScanGauge KR are built specifically for heavy diesel, connecting directly to your truck's 9-pin J1939 or 6-pin J1708 diagnostic port to give you real-time engine data where you need it most — right in the cab.

Monitor coolant temperature, engine load, RPM, fuel consumption and more across multiple live gauges as you drive. Read and clear fault codes on the spot without waiting for a workshop — critical when you're on a long haul far from town. Five trip computers track your kilometres, hours, fuel used and fuel cost across every run so you always know what each trip is costing you.

No laptop required. No app. No subscription. Just plug in and drive with confidence.
