ELM OBD2 Car Scanner

Discover what your car is doing in realtime. Read OBD fault codes, monitor car performance, access sensor data and much more!

Car Scanner is a vehicle diagnostics, car performance, trip computer and scanner tool that connects to your OBD2 engine management system / ECU through an OBD II Wi-Fi or Bluetooth adapter.

Car Scanner provides a wide range of useful features:

1. Create and customize your own dashboard using the gauges and charts you prefer.

2. Add custom extended PIDs to access information that may be hidden by the car manufacturer.

3. Read and reset DTC fault codes directly from your phone, just like a diagnostic scantool. Car Scanner also includes a large database containing DTC codes and their descriptions.

4. View freeze-frame data to check the state of available sensors at the moment a DTC fault code was stored.

5. Use Mode 06 to access ECU self-monitoring test results. This information can help you understand vehicle issues and reduce unnecessary repair costs.

6. Check whether your car is ready for an emission test.

7. View all available vehicle sensors together on one screen.

A compatible OBD2 ELM327 adapter is required for the app to work. Supported connection types include Wi-Fi, Bluetooth and Bluetooth 4.0 Bluetooth LE.

The ELM327 device connects to the diagnostic socket inside your car and allows your phone to communicate with the vehicle diagnostics system.

Compatible adapter brands may include OBDLink, Kiwi 3, V-Gate, Carista, LELink and Veepeak.

When purchasing a low-cost OBD2 ELM327 adapter from eBay, Amazon or another marketplace, check whether it is marked as version 2.1. These adapters may be supported, but some models can contain hardware or connection issues.

PLEASE NOTE:

Vehicle ECUs differ in the number and type of sensors they support. Car Scanner cannot display information that is not provided by your vehicle.

ADAPTER WARNING:

Some low-quality or cloned adapters may fail to connect correctly to the smartphone or vehicle. They may also lose connection, increase the delay when reading data or cause unstable communication with the car engine.

For more reliable diagnostics and connection stability, use a genuine ELM327 device or a compatible adapter from a recognized manufacturer.
