AlfaOBD stands out as specialized diagnostic software tailored for vehicles from the Stellantis group, formerly known as Fiat Chrysler Automobiles (FCA). Specifically, it offers in-depth diagnostics for 1994 – 2023 Fiat, Alfa Romeo, and Lancia models, along with 2005 – 2023 Chrysler, Dodge, Ram, and Jeep vehicles. For detailed compatibility, refer to the Supported Vehicles list.
Designed to meet the needs of car owners while incorporating features typically found in professional scanners, AlfaOBD goes beyond generic OBD2 applications. Unlike standard OBDII/EOBD tools that provide limited access primarily to engine and transmission systems (and sometimes ABS), AlfaOBD directly supports a wide array of Electronic Control Units (ECUs).
AlfaOBD is versatile, available for both Windows PC (XP, 8, 8.1, 10, 11) and Android (4.0.3 and later) platforms. Functionally identical across both platforms, the choice between Windows and Android versions largely depends on user preference and convenience.
Important Note: Be aware that the “Alfa OBD2 app” on the Apple App Store is a separate, unrelated product and not the authentic AlfaOBD software for iPhones.
For Mac users, the Windows version of AlfaOBD can be run through Parallels or Bootcamp. However, on M1 Macs using Parallels, only WiFi OBD interfaces are compatible. Intel Macs using Parallels support USB and WiFi interfaces. For Bluetooth/USB/WiFi interfaces on Intel Macs, Bootcamp Windows installation is required.
Key Features of AlfaOBD for Enhanced OBD2 Diagnostics
AlfaOBD provides a comprehensive suite of features that elevate OBD2 diagnostics, offering capabilities far beyond basic code reading:
- Real-time Parameter Monitoring: Track a wide range of dynamic parameters from engine, transmission, body, dashboard, ABS, climate control, and more. Data can be displayed graphically as customizable plots for easy analysis.
- Static Data Retrieval: Access crucial static information such as ECU identification, system status, and fault codes (DTCs) accompanied by potential causes and environmental data (freeze frames) when available.
- Fault Code Management: Clear stored fault codes (DTCs) and actively monitor the system for the reappearance of any new issues.
- Active Diagnostics and Configuration: Perform active diagnostic tests and configuration procedures for various vehicle systems managed by ECUs. This includes service light resets, engine oil change procedures, DPF regeneration, ABS bleeding, air suspension maintenance, transmission calibration, and numerous other functions.
- Electronic Key and RF Remote Programming: Program electronic keys and RF remote controls for certain vehicle models, adding convenience and security.
- Vehicle Configuration Adjustment: Modify vehicle configuration settings, enabling the activation of newly installed components within the Body Computer configuration through Proxy alignment. This is crucial for customizing and upgrading your vehicle’s features.
Essential Hardware for Using AlfaOBD with Your Vehicle
To fully utilize AlfaOBD’s capabilities, you will need specific hardware components to interface with your vehicle’s OBD2 system:
1. Security Gateway Bypass (SGW) for Newer Models (2018+)
For vehicles manufactured from 2018 onwards (starting with the 2017 Fiat 500L), Stellantis (FCA) implemented a Security Gateway Module (SGW) to prevent unauthorized diagnostics. Currently, AlfaOBD does not offer a software-based bypass solution. Therefore, a hardware SGW bypass module is necessary to circumvent this security measure.
Owners of Alfa Romeo Giulia/Stelvio, Fiat 500X/Argo/Chronos/Toro, Jeep Renegade/Compass MP, Ducato Serie 8, and RAM ProMaster 2022+ must ensure their chosen bypass module supports the second high-speed CAN bus, which is connected to pins 12 and 13 of the OBD port.
Here are some recommended SGW bypass options categorized by region:
North America:
- https://www.zautomotive.com/product/z_dbp/ – For 2018+ Dodge/Chrysler/Jeep vehicles.
- https://www.zautomotive.com/product/z_sgw/ – Universal for all Stellantis (FCA) vehicles, including Alfa Romeo and Fiat platforms with the second High-Speed CANBUS (e.g., Alfa Romeo Giulia/Stelvio, Fiat 500X/Toro/Jeep Renegade/Compass MP).
- https://www.kaodtech.com/product-page/security-module-bypass – For RAM/Dodge/Jeep.
- https://ecri.app/products/ecri-security-module-bypass-2018-jeep-ram – Specifically for 2018+ Jeep and RAM models.
Europe:

- https://www.obdauto.fr/cable-sgw-special-vehicules-fca-8-voies-12-voies-c2x29793057
While other compatible bypass modules may work, always verify compatibility with the distributor or manufacturer to ensure proper function.
For guidance on SGW location and bypass installation, consult resources such as:
It is advisable to disconnect the SGW bypass before taking your vehicle to a dealership, as diagnostic tools used by dealers may not function correctly with the bypass installed.
2. OBD Interface
To establish communication between AlfaOBD software and your vehicle, you will need a compatible OBD interface. The specific interface and any necessary colored adapters depend on your vehicle model. Refer to the Supported Vehicles list for recommendations tailored to your car.
AlfaOBD currently supports several interface types:
Note: K-Line USB interfaces are not compatible with Android due to operating system limitations. CAN USB interfaces are supported on Android devices via On-The-Go (OTG). Ensure your Android device supports OTG and acquire a suitable adapter if needed.
Note: Some WLAN interfaces offer built-in Android support, like OBDLink MX+ WiFi. WLAN connectivity with other interfaces on Android may require devices with ad-hoc Wi-Fi support enabled, which often necessitates rooting the device and replacing the Wi-Fi driver with a modified version. Before purchasing a WLAN interface for Android AlfaOBD, confirm your device’s ad-hoc Wi-Fi capabilities.
3. Colored Adapters
Depending on your vehicle model year and the OBD interface you choose, additional colored adapters may be required. Again, the Supported Vehicles list provides guidance on recommended adapters for specific vehicles.
AlfaOBD conveniently displays the necessary adapter type and suggested OBD interface on its selection screen when you choose a control module. The app also prompts with a “Connect adapter…” message before initiating a connection.
Important Note: When using OBDLink MX+/EX, ELS27, or Vgate vLinker FD/FD+/MC/MC+/FS interfaces, a “blue” adapter is generally not needed. Simply close any “Connect blue adapter” prompts and proceed with the connection.
“Grey” Adapter Required for:
- Alfa Romeo Giulia/Stelvio
- Fiat 500E (2020+)/500X/Argo/Chronos/Ducato Serie 8 (2022+)/Toro
- Jeep Renegade/Compass (MP)
- RAM Pro Master (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 (types 250 and 290 before 2022)/Doblo (type 152/263)
- RAM Pro Master (before 2022)/Pro Master City
These adapters are readily available from various suppliers, including:
- Electronic-Fuchs.de
- Obdauto.fr
- Gendan.co.uk
- Amazon and eBay
