AI ELM: OBD2 Car Scanner

Check Engine light on? Find out why in a minute: AI ELM reads the fault codes (P0420, P0171, P0300…) and explains in plain words what they mean, how urgent they are and what to check first.

AI ELM turns a cheap ELM327 adapter into a clear car diagnostic tool. Plug it into the OBD-II port, connect over Bluetooth or Wi‑Fi and see what your car is telling you — in plain words.

FAULT CODES WITH MEANING
• Stored, pending and permanent codes with a description
• Freeze frame: the engine conditions when the code was set
• Readiness monitors and how often self-tests run
• Clear codes — after the app saves a report

LIVE DATA AND RECORDING
• Engine speed, temperatures, fuel trims, load and more
• History graphs and min/max for every value
• Record a drive with markers and export it as CSV
• Recording keeps running in the background

CHECK A USED CAR BEFORE BUYING
• VIN check and control unit software
• Recently cleared codes and incomplete monitors — what a seller may be hiding
• A report you can share with a mechanic

AI EXPLANATION
• The AI reads codes, live values and your notes and explains the likely cause and next steps
• Pay only for what you use: credits or a subscription

FREE AND FAIR
• Reading codes, live data and reports are free
• Fault codes with descriptions and freeze frame are free; the used-car check, recording and monitor tests open for a short video or a credit

WORKS WITH YOUR ADAPTER

AI ELM reads standard OBD-II data available on petrol cars sold in the EU since 2001, diesels since 2004 and US cars since 1996. AI conclusions do not replace an inspection at a workshop.
