RIGCHECK: Semi Truck Repair

RIGCHECK is the truck repair and diagnostics app built for semi truck drivers and owner operators — not cars. Heavy-duty J1939 fault codes, dashboard warning lights, DVIR pre-trip inspections, and an AI diesel mechanic that knows your rig. Works offline, in English and French, with no adapter or dongle required.

WHAT'S WRONG WITH MY TRUCK? Describe the symptom — hard start, DEF light, derate, air leak — and get a clear Safe / Caution / Stop answer with driver-safe steps and when to call a pro. Symptom-first truck troubleshooting, sorted by urgency.

TRUCK FAULT CODES — NO ADAPTER NEEDED Look up heavy-duty J1939 SPN/FMI fault codes, or point your camera at the dash and let RIGCHECK read the code screen for you. Built for Class 8 diesel trucks: Freightliner, Kenworth, Peterbilt, Volvo, Mack, International, Western Star.

DASHBOARD WARNING LIGHTS EXPLAINED Heavy-truck warning lights identified — snap a photo of the lit lamp and get what it means, how urgent it is, and what to do next. DEF light, DPF regen, check engine, ABS and more.

PRE-TRIP INSPECTION / DVIR / CIRCLE CHECK Region-aware daily inspection for the US (FMCSA DVIR) and Canada (NSC circle check). Log defects, certify, and keep your inspection history.

MAINTENANCE LOG & SERVICE REMINDERS Track service history per truck and get mileage-based reminders — oil changes, filters, PM schedules — built for owner operators and small fleets.

WINTER & ROADSIDE Cold-weather pack with real forecasts and winter diesel advice (gelling, DEF freezing, cold starts). Find truck repair shops, tire service and towing nearby when you break down.

ASK RIGCHECK — AI DIESEL MECHANIC Chat or talk hands-free. Answers come from reviewed heavy-truck guidance, and safety severity is never left to the AI. Guidance only — always confirm safety-critical work with a qualified technician.

Offline-first: your fault code reference, warning lights and inspections work in dead zones. Bilingual English / Québec French. No ELD hardware required.
