Diagnose and reset your car's trouble codes with ease using the OBD Arny diagnostic scanner. This simple-to-use app adheres to the OBD2 standard, providing valuable insights into your vehicle's health.
Important Notes:
- You'll need an ELM327 Bluetooth or Wi-Fi adapter to connect to your car's OBD2 port.
- Ensure your vehicle is OBD2 compatible.
- ELM adapter version 1.5 is recommended; version 2.1 adapters are prone to corruption.
Getting Started:
- Download the Obd Arny app.
- Enable Bluetooth on your device.
- Discover your ELM adapter (Bluetooth versions only).
- Select your adapter in the app's settings.
- Begin scanning your car.
Diagnostic Capabilities:
Using Obd Arny with your Bluetooth/Wi-Fi ELM327 adapter, you can:
- Scan and read basic vehicle information according to the OBD2 standard.
- Perform diagnostics, reading and clearing trouble codes (DTCs) from the Electronic Control Unit (ECU).
- Access live data, including speed, RPM, engine coolant temperature, engine load, short/long term fuel trim, fuel and air pressure, and more.
A demo mode is available to explore the app's features without connecting to a vehicle (ELM327 adapter not required).
Full Version Features:
The free version has limited functionality. Upgrade to the full version for:
- Ad-free experience.
- Access to diagnostic trouble codes hidden in the free version.
- Ability to select up to 10 live data parameters (instead of 3).
- Freeze frame data access.
Note: The number of supported live data parameters depends on your vehicle, not the app version.
