FAQ

Q: How do I establish a connection between my phone and my vehicle?

A: To get started, you will need a separate ELM327-compatible adapter that plugs into your car’s OBD2 diagnostic port, which is usually located under the dashboard near the steering wheel. Once the hardware is plugged in, you can connect the app to the adapter via Bluetooth, Bluetooth Low Energy (BLE), or Wi-Fi depending on the specific model of adapter you have purchased.

Q: Will this app work with my specific car model?

A: The software is designed to be compatible with all OBD2 and EOBD compliant vehicles sold across the globe, which generally includes most gasoline cars manufactured after 1996 in the United States and after 2001 in Europe. However, because every vehicle is a bit different, the specific parameters and sensors you can view will ultimately depend on what your car's electronic control unit is programmed to share.

Q: Can I use this tool to turn off my Check Engine light?

A: Yes, one of the most helpful features of the app is the ability to read Diagnostic Trouble Codes and reset the Check Engine light once you have fixed the underlying problem. It also provides freeze frame data, which captures a snapshot of sensor values at the exact moment a fault occurred to help you diagnose the issue with much higher accuracy.
