FINDS THE REAL CAUSE, NOT JUST THE CODE
ScanFixAI reads every module in your vehicle and thinks like a seasoned mechanic — it examines everything connected to a fault to find the real cause, then tells you what to check, what to do, and what not to replace. It’ll even ride along on a Test Drive, watching your live data as you drive and talking you through what it finds — like having a mechanic in the passenger seat.
Plus: reads every module, AI root cause analysis, vehicle coding, used car inspection with odometer fraud detection, and a BUY or DON'T BUY verdict. Works on Ford, GM, Toyota, Honda, Chrysler, BMW, VW/Audi, Mercedes, Nissan, Hyundai, and more.
Free to start — includes a 24-hour Pro trial, no card required.
📱 Coming soon to the Google Play Store as ScanFixAI - Car Diagnostics — the official app by ScanFixAI (not the other “ScanFix AI” currently listed there).
WHY WE BUILT IT
Diagnosing a car used to mean one tool for codes, another for ABS and airbags, a brand-specific tool for coding, and a subscription for repair data — each doing one job, none talking to each other. We replaced that whole shelf with one program that does what all of them do, and added AI that actually diagnoses the problem instead of just reporting a code.
INDUSTRY FIRST
ScanFixAI gets smarter with every scan. When the app encounters an issue on your vehicle, our AI automatically identifies the problem, fixes it, and pushes an update — no waiting, no manual patches. The more people use it, the more accurate it becomes.
Connect and scan your vehicle normally.
Anonymized results are analyzed by our AI in real-time.
Issues are identified and fixed automatically — no human delay.
App updates with improvements. You do nothing.
No personal data is ever collected. All telemetry is anonymized. Privacy Policy
Think like a master mechanic. When a scan finds a problem, the AI examines everything connected to that fault to pinpoint the real root cause — then tells you what to do, and what not to replace. No guessing, no parts-cannon.
One tap: Scan My Car. Plain-English results anyone can understand — with every pro tool one tap away when you want it. Simple when you need it, powerful when you don't.
Don't just read codes — understand them. ScanFixAI cross-references DTCs across all modules to find the actual root cause, not just symptoms.
Basic code readers only see the engine. ScanFixAI reads PCM, TCM, ABS, BCM, airbag, steering, APIM, and 19 more — nothing hidden.
No more Googling P0171. ScanFixAI tells you "Both banks running lean — likely vacuum leak, bad MAF, or weak fuel pump" with step-by-step fix instructions.
Built-in tests like the Vacuum Leak Confirmation — samples fuel trims at idle vs. rev and tells you definitively if there's a leak. No smoke machine needed to confirm.
Monitor everything in real-time: fuel trims, boost pressure, transmission temp, turbo RPM, wastegate position, and 62 more — with anomaly detection.
Read current as-built data from any module and compare it side by side against factory values. Changed bytes are highlighted in orange so you can see exactly what's been modified. Ford: automatic factory lookup via Motorcraft by VIN. BMW: reads the factory order (FA) directly from the vehicle. All other makes: auto-saves a baseline on first read for future comparison. Edit and write as-built changes back to modules — customize, restore, or clone configurations with confidence.
Customize your vehicle like the dealer can. Enable DRL, needle sweep, exhaust burble, digital speedometer, comfort close, launch control, and more. Deep verified coverage for Ford, GM, BMW, VW/Audi with coding profiles confirmed via real CAN captures. Other makes supported via community data — growing every day.
Like having a master tech riding shotgun. Drive mode monitors your vehicle in real-time, detects issues on the road, talks to you through your speakers, and tells you when to pull over — then walks you through the fix.
Every scan is saved by VIN. Track how your vehicle changes over time, compare past scans, and prove to a buyer or mechanic exactly what was fixed and when.
Test your battery and charging system. Checks voltage, state of charge, and alternator output. Know if your battery is dying before you get stranded.
Don't get scammed. ScanFixAI compares odometer readings across every module in the car — if the dash says 60K but the transmission computer says 120K, the odometer was rolled back. Also checks if someone recently cleared codes to hide a check engine light (incomplete readiness monitors = red flag). Tests battery health, scans all modules for hidden problems, and gives you a health score with a clear BUY, CAUTION, or DON'T BUY verdict. Print the report and negotiate the price down — or walk away.
Add your shop name, logo, and contact info to every health report. Hand customers a professional printout that looks like a $5,000 diagnostic setup.
Replacing a module? Backs up the old config, writes it to the new one, and verifies the transfer — just like the dealer does.
No adapter? No problem. Describe your symptoms in plain English and the AI mechanic tells you what's likely wrong, what to check first, and whether it's safe to drive. Works without any OBD connection.
Snap a photo of a warning light, a leaking part, or visible damage. AI analyzes the image and tells you what it is, what caused it, and what to do about it.
759 fixes built from real repair data. When you get a trouble code, ScanFixAI shows the most likely fix with a percentage — not a guess, a statistic from actual repairs.
ScanFixAI automatically checks for open recalls after every scan — no extra step needed. If your VIN has an active safety recall, you'll know immediately. Don't find out about a dangerous defect the hard way.
"Is it safe to drive?" — the first question everyone asks. ScanFixAI rates 163 common trouble codes by severity: Critical (pull over now), Moderate (schedule repair soon), or Low (monitor it). No more panic over a loose gas cap, no more ignoring a failing catalytic converter.
16 maintenance items tracked across 20+ makes with make-specific intervals. Oil, brakes, spark plugs, transmission fluid, coolant, belts, and more — with safety-critical flags so you know which services actually matter for keeping the car reliable vs. which ones the dealer is just trying to sell you.
Running a used car check? Generate a professional PDF inspection report with health score, mileage verification, code history, and a clear BUY/CAUTION/DON'T BUY verdict. Hand it to the seller or keep it for your records.
Heads-up display mode for driving. Shows speed, RPM, coolant temp, and active warnings in a clean, glanceable layout designed for the road.
Automatically logs your trips with GPS tracking. Review routes, distances, and driving stats. Great for mileage tracking, fleet management, or just seeing where you've been.
Track real-time and average fuel consumption using live OBD data. See how your driving habits affect fuel economy and find out what's costing you at the pump.
Search a database of 95,630 real complaints filed with NHTSA by actual vehicle owners. See what problems other people are having with your exact year, make, and model — before they happen to you.
Every service reset and bidirectional function shows a confidence badge: VERIFIED (confirmed via CAN captures on real vehicles), COMMUNITY (reported working by users), or EXPERIMENTAL (untested). We don't pretend everything works perfectly on every car — we tell you exactly what's been proven. Verified coverage: Ford, GM, BMW, VW/Audi. Growing daily from user reports.
