Additionally, the app can show and reset DTC fault codes and includes a large database of DTC code descriptions.

Car Scanner also allows you to read free-frames, which are sensors states when a DTC is saved. It also offers Mode 06, which provides ECU self-monitoring test results to help you fix your car and keep repair costs down. The app can also check if your car is ready for emission tests and display all sensor readings on one screen.

Car Scanner is compatible with any vehicle that uses the OBD 2 standard, which includes most vehicles built after 2000. It can even work for vehicles as far back as 1996. The app also includes a variety of connection profiles for different car brands, such as Toyota, Mitsubishi, GM, and more.

In addition to its diagnostic capabilities, Car Scanner also offers a HUD mode to project data onto your windshield, as well as a tool for accurate acceleration measurements and trip computer features. It even supports coding for certain car models, allowing you to change hidden settings.

To use the app, you will need a Wi-Fi or Bluetooth OBD2 ELM327 compatible adapter. It is recommended to use reputable brands such as OBDLink, Kiwi 3, or V-Gate. Cheap Chinese adapters may also work, but they may have bugs and can potentially cause issues with your car's engine.

It is important to note that the app's features may vary depending on the sensors supported by your vehicle's ECU. Some adapters may also have trouble connecting to the app or your car, so it is recommended to use genuine or recommended brands for a smoother experience.
