AlfaOBD is a powerful diagnostic software designed for vehicles manufactured by Stellantis (formerly Fiat Chrysler Automobiles). This comprehensive guide will cover everything you need to know about using a mini OBDII device with AlfaOBD on your Android device, empowering you to diagnose and customize your vehicle like a pro.
Compatibility and Supported Vehicles
AlfaOBD supports a wide range of vehicles, generally including:
- Fiat/Alfa Romeo/Lancia: 1994-2023 models
- Chrysler/Dodge/Ram/Jeep: 2005-2023 models
For a detailed list of supported models, refer to the official AlfaOBD website’s Supported Vehicles page. Unlike generic OBDII/EOBD apps that offer limited access to engine and transmission modules, AlfaOBD provides in-depth access to various Electronic Control Units (ECUs), enabling comprehensive diagnostics and customization.
Important Note: The “Alfa OBD2” app available on the Apple App Store is not affiliated with AlfaOBD and is a different product.
AlfaOBD Features
AlfaOBD boasts a wide array of features, including:
- Live Data Monitoring: Monitor dynamic parameters of the engine, transmission, body, ABS, climate control, and more, with adjustable graphical plots.
- Diagnostic Trouble Codes (DTCs): Read and clear fault codes, along with probable causes and freeze frame data.
- Active Diagnostics and Configuration: Perform service light resets, oil changes, DPF regeneration, ABS bleeds, air suspension maintenance, transmission calibrations, and more.
- Key Programming: Program electronic keys and RF remote controls on select models.
- Vehicle Configuration: Adjust car settings and activate newly installed equipment.
Hardware Requirements
To use AlfaOBD on your Android device, you’ll need the following:
1. Security Gateway Bypass (for 2018+ Models)
Stellantis vehicles from 2018 onwards often include a Security Gateway Module (SGW) that blocks third-party diagnostics. To bypass this, you’ll need a hardware SGW bypass module. Ensure the bypass supports the second high-speed CAN bus (pins 12 and 13 of the OBD socket) for vehicles like Alfa Romeo Giulia/Stelvio, Fiat 500X/Argo/Chronos/Toro, Jeep Renegade/Compass MP, Ducato Serie 8, and RAM ProMaster (2022+).
Recommended SGW bypasses include:
- North America: Z Automotive, KAOD Tech, ECRI
- Europe: Electronic-Fuchs, OBDAuto
Consult your bypass manufacturer for compatibility confirmation.
2. OBD Interface
You’ll need a compatible mini OBDII interface to connect your Android device to your vehicle. Recommended interfaces vary depending on the car model. Consult the AlfaOBD Supported Vehicles page for specific recommendations.
Important Notes:
- KLLine USB interfaces are not supported on Android. CAN USB interfaces are supported via On-The-Go (OTG).
- Some WiFi interfaces require ad-hoc Wi-Fi support, which may require rooting your Android device.
3. Colored Adapters
Depending on your car model and OBD interface, you may need a colored adapter. The AlfaOBD app will indicate the required adapter type.
- Grey Adapter: Required for Alfa Romeo Giulia/Stelvio, Fiat 500E (2020+), 500X/Argo/Chronos/Ducato Serie 8 (2022+), Toro, Jeep Renegade/Compass (MP), RAM ProMaster (2022+).
- Yellow Adapter: Required for Alfa Romeo Giulietta/Mito/4C, Fiat 500/500E (before 2020)/500L/Panda (2012+)/Punto EVO/Grande Punto, Fiat Professional Ducato (pre-2022)/Doblo, RAM ProMaster (pre-2022)/ProMaster City.
Adapters are available from various online retailers.

AlfaOBD, combined with a mini OBDII adapter for Android, offers a powerful and versatile solution for diagnosing and customizing your Stellantis vehicle. By understanding the hardware requirements and leveraging the software’s extensive features, you can unlock a new level of control over your car’s maintenance and performance.
