Are you looking to understand what’s happening under the hood of your car in real-time? Do you want to decode those mysterious OBD fault codes without a trip to the mechanic? Car Scanner is your powerful vehicle performance, trip computer, and diagnostic tool, functioning as a scanner using an OBD II Wi-Fi or Bluetooth 4.0 adapter to connect to your car’s OBD2 engine management system, or ECU. This app delivers a wealth of features, and remarkably, offers a wide array of them for free.
Car Scanner isn’t just another OBD2 app; it’s designed to give you unparalleled insight into your vehicle’s operation. Here are some of the standout features you can access, many of them completely free:

Getting Started with Your Free OBD2 Scan App
To unleash the full potential of Car Scanner, you’ll need an OBD2 ELM327 compatible adapter. This device is essential for creating the connection between your car and your smartphone.
-
Choosing the Right OBD2 Adapter: The app requires a Wi-Fi or Bluetooth 4.0 (Bluetooth LE) OBD2 ELM327 compatible adapter to function. These adapters plug into your car’s diagnostic socket, providing your phone with access to vehicle diagnostics. Recommended adapter brands include Kiwi 3, Viecar, V-Gate, Carista, LELink, and Veepeak.
-
Adapter Cautions: Be cautious of very cheap, unbranded OBD2 ELM327 adapters, particularly those marked as v.2.1 from online marketplaces. While some may function, they are often plagued with bugs, potentially causing connection issues, unstable engine operation, data lag, and other problems. It’s advisable to invest in genuine ELM327 adapters or those from the recommended reputable brands for reliable performance.
Free vs. Paid: Unlocking Even More Power
Car Scanner ELM OBD2 is generously offered for free, providing a vast array of features that surpass many other apps in the market. However, to unlock the full spectrum of capabilities, including advanced features and in-depth customizations, a one-time purchase or subscription is available. The free version itself is incredibly robust, making it an excellent starting point for anyone interested in OBD2 diagnostics.
Important Usage Note: It’s crucial to understand that the amount of sensor data accessible varies depending on your vehicle’s ECU capabilities. Car Scanner can only display information that your car’s manufacturer makes available.
