About RigMedic

RigMedic turns a fault code, symptom, or VIN into a clear, ranked diagnosis — built for mechanics, fleets, owner-operators, and DIY diesel owners who need an answer fast.

How it works
1

Enter what you know

A fault code (OBD-II or J1939), a plain-language symptom, or a 17-character VIN — any one is enough to start.

2

We match the data

We pull the relevant fault codes, decode the VIN, and match applicable recalls and technical service bulletins for your engine.

3

Get a ranked diagnosis

Probable causes ranked by real-world fix rates, the next checks to run, and the parts you'll likely need — in seconds.

Who it's for

Independent shops, fleet operators, owner-operators, and roadside DIY. Diagnostics is free to try; Pro and Fleet plans add unlimited use, VIN history, and multi-vehicle tools.

The data behind it

RigMedic is grounded in structured OBD-II and SAE J1939 fault-code intelligence plus public NHTSA recalls and TSBs — and it gets sharper as mechanics confirm what actually fixed each problem.
