Free with a 1-year subscription, the ChatMecano OBD2 connector reads active and hidden (pending) Check Engine codes before the light even comes on — an extraordinary tool for mechanics, DIY repairers and any driver who wants to know their vehicle.
An AI assistant for mechanics is powerful. But an AI assistant that actually gets inside the vehicle is something else entirely. That's exactly what the ChatMecano OBD2 connector — free with a 1-year subscription — delivers: plugged into the vehicle's OBD2 port, it gives the AI direct access to engine and electronic system data, for diagnostics that are far more precise and far more meaningful than a description of symptoms alone.
Its most spectacular strength? Reading active AND hidden Check Engine codes. Hidden codes — pending and permanent codes — don't light up the dashboard yet, but they're already stored in the vehicle's computer. The ChatMecano connector reveals them, and the AI translates them into plain language: likely cause, severity, checks to run and the recommended repair. You diagnose before the breakdown, not after.
It's an extraordinary tool for the professional mechanic, who saves precious time by arriving at the vehicle with the likely cause already identified. For the DIY repairer, it's the confidence of knowing exactly which part to check before taking anything apart. And for the everyday driver or the tourist, it's the freedom of having complete information about their vehicle at all times — before a long road trip, when buying a used vehicle, or simply whenever something feels different behind the wheel.
Plugged in under the dashboard in seconds, the connector talks over Bluetooth to the ChatMecano app on any mobile phone. The AI then combines the codes it reads with photo VIN decoding, recommended maintenance and manufacturer specifications: a complete picture of the vehicle, from engine to transmission, always at hand. Discover the OBD2 Check Engine AI analysis.
And because we believe this tool belongs in the hands of everyone who looks after a vehicle, the OBD2 connector is free — shipping included in Canada, the United States, Mexico and France — with every annual ChatMecano subscription. A small device plugged in once, monitoring your vehicle permanently.
