Before you start.
And for the road ahead.

Plug a compatible OBD2 adapter into the diagnostic port, then follow Car AI’s connection steps. Check Bluetooth permissions and stay near the parked vehicle.

Powertrain, year, vehicle market and adapter affect the data you can access. An OBD2 port alone does not guarantee access to every system.

Start with something you can see: “What does this code mean?”, “What should I keep for maintenance?” or “How should I interpret this reading?”. Continue the conversation by text or voice.

Check that it is plugged in and powered, then check phone permissions and Bluetooth. Stay near the vehicle. Restart the search in Car AI, following the manufacturer’s instructions; some adapters use a specific pairing method.

Ignition state, vehicle initialization and supported sensors affect what is displayed. Check the latest update and wait for the connection. Missing data does not necessarily mean a fault.

Move the phone closer to the vehicle and check that the adapter remains powered. Check app permissions and your adapter’s instructions. If the problem persists, send us the adapter model, phone model and Car AI version.

Keep the exact code, date and observed symptoms. A persistent fault should be reviewed with the professional who carried out the repair. Clearing the code does not confirm that its cause has gone away.
