Athrun - AI Auto Diagnostics

Athrun turns your car's warning lights and trouble codes into clear, plain-English answers. Describe a symptom, paste a diagnostic trouble code, or scan your vehicle directly — and Athrun's AI explains what's likely wrong, how urgent it is, and what it typically takes to fix. Built for everyday vehicle owners, not just mechanics. KEY FEATURES AI Diagnostic Chat — Describe a noise, a rough idle, or a check-engine light in your own words. Athrun ranks the likely causes by probability, flags how serious the issue is, and walks you through what to do next. Live OBD-II Scanning — Pair a compatible Bluetooth OBD-II adapter to read stored trouble codes, your VIN, and battery voltage straight from your vehicle. Trouble-Code Library — Look up any DTC (P, B, C, and U codes) for a clear explanation of what it means and what commonly triggers it. Manufacturer Service Bulletins — See what the manufacturer has documented for your specific vehicle. Safety Recall Lookup — Find open NHTSA recall campaigns that apply to your vehicle by VIN or by make, model, and year. VIN & License-Plate Decoding — Identify a vehicle by typing a VIN, scanning it with your camera, or looking it up by license plate, so codes, parts, and guidance are matched to the right car. Your Garage — Keep every vehicle in one place with mileage, service history, oil-change timing, and registration reminders. Fit-Matched Parts — Search parts narrowed to your vehicle so you order the right component the first time. Nearby Services — Locate auto-repair shops close to you when you'd rather hand the job to a professional. Community Forum — Ask questions, share fixes, and learn from other vehicle owners. IMPORTANT Athrun is an informational tool to help you understand your vehicle. It is not a substitute for inspection, diagnosis, or repair by a qualified automotive professional. Always confirm with a professional before performing repairs or relying on any code, part, or recommendation surfaced by the app. Parts fitment is estimated — confirm fit before purchasing.
