By using OBD2 Scanner Pro you agree to the terms below. This text is provided for transparency and is not legal advice.
The app is an informational diagnostic tool. It reads data your vehicle makes available over generic OBD-II and presents it. It is not a mechanic, an inspection authority, a safety system or a vehicle-control system.
Diagnostic trouble codes identify where a fault was detected. They do not confirm which component failed. The app does not guarantee any diagnosis, and readings can be delayed or inaccurate depending on the adapter, vehicle and conditions. Consult a qualified service professional for repairs.
Clearing diagnostic codes erases stored emissions information and resets readiness monitors. It does not repair the vehicle, and a code will return if the underlying condition persists. Do not use code clearing to obscure a fault before an emissions inspection.
Do not interact with the app while driving. Mount your device securely. Performance tests must only be used where they are legal and safe.
The app supports Wi-Fi ELM327-compatible adapters over TCP and BLE/GATT ELM327-compatible adapters. Compatibility depends on the adapter, vehicle, ECU and the OBD-II modes and PIDs that vehicle supports. Compatibility with every adapter on the market is not guaranteed.

Use of the app is governed by Apple's Standard End User Licence Agreement, available from Apple.
