## What is DTC?

DTC-TOOL turns your iPhone into a pocket scanner for heavy-duty trucks. Designed for owner-operators, truck drivers and small fleets needing roadside self-checks and workshop-grade fault reading — no bulky bench scanner required.

• Read DTCs – active/historical fault codes with plain-language fixes (Cummins, Detroit, Volvo, Mack, Freightliner, Isuzu, HINO & more, auto-detects J1939/J1708 protocols)
• Clear DTCs – clear stale fault codes after a repair and get back on the road
• Live PID stream – voltage, oil pressure, coolant temp, RPM, load, DPF soot load in real time
• DPF care – parked regeneration & soot load reset guidance (ECU-permitted only)
• VIN reading & ECU parameter viewing – read-only by default; write operations are only permitted when allowed by the vehicle ECU
• Offline session logs – past scans saved locally to track vehicle trends between service visits

How it works: Plug a Bluetooth OBD adapter into your truck, launch the app, and it auto-pairs. No manual protocol configuration required.

No OBD adapter on hand? Tap the Help Center​ tab → Demo mode​ to instantly load a sample J1939 truck: active/historical DTCs, live PID chart, DPF soot status, and clear-DTC flow. No Bluetooth dongle or vehicle required.

Note: DTC-TOOL is a diagnostic viewer/guide tool. It does not stream cloud telematics and cannot replace OEM software.
