Your check engine light is on. Now what? Auto AI Diagnostics turns your iPhone into an AI-powered car diagnostic tool. Plug a Bluetooth OBD2 adapter into the port under your dash, tap scan, and AXEL โ your AI shop foreman โ reads the fault codes straight from your car's computer and explains what's going on in plain English or Spanish: what's happening, how serious it is, whether it's a DIY fix or a shop job, and what to do next. FEATURES: โข Real fault codes pulled straight from your car's computer โ engine and control modules โข Automatic VIN read directly from your vehicle's ECU โข AI-powered diagnosis with evidence and an action plan โ not just a code definition โข Fault code descriptions verified against the web for accuracy โข View Conditions: see the mileage, battery voltage, and speed recorded when each fault set โข Live engine data โ RPM, coolant temp, battery voltage, throttle, and more โข Odometer tracking with every scan โข Scan history so you can track issues over time โข DIY repair guidance and YouTube repair video suggestions for your exact vehicle โข Ask AXEL follow-up questions about your specific car โข Works with older, pre-2008 (K-line) vehicles too โข The entire app in English or Spanish โ including AXEL's AI diagnosis. Switch anytime. WHAT YOU NEED: A Bluetooth OBD2 adapter (ELM327-compatible, sold separately). It plugs into the OBD port under the dashboard on the driver's side โ and on iPhone there's no pairing needed, the app finds it automatically. Works with most gas-powered cars and light trucks sold since 1996 (OBD2), including many pre-2008 K-line vehicles. Auto AI Diagnostics helps you understand your car and make informed decisions โ it's information and guidance, not a substitute for a professional inspection when safety is on the line.
