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 ā your AI shop foreman ā 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: ⢠Real fault codes pulled straight from your car's computer ā engine and control modules ⢠Automatic VIN read directly from your vehicle's ECU ⢠AI-powered diagnosis with evidence and an action plan ā not just a code definition ⢠Fault code descriptions verified against the web for accuracy ⢠View Conditions: see the mileage, battery voltage, and speed recorded when each fault set ⢠Live engine data ā RPM, coolant temp, battery voltage, throttle, and more ⢠Odometer tracking with every scan ⢠Scan history so you can track issues over time ⢠DIY repair guidance and YouTube repair video suggestions for your exact vehicle ⢠Ask AXEL follow-up questions about your specific car ⢠Works with older, pre-2008 (K-line) vehicles too ⢠The entire app in English or Spanish ā 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 ā 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 ā it's information and guidance, not a substitute for a professional inspection when safety is on the line.
