AlfaOBD is specialized diagnostic software designed for vehicles from the Stellantis group, formerly known as Fiat Chrysler Automobiles (FCA). This includes a wide range of models from 1994 to 2023 for Fiat, Alfa Romeo, and Lancia, and from 2005 to 2023 for Chrysler, Dodge, Ram, and Jeep. For a comprehensive list of supported models, please refer to the Supported Vehicles list on the official AlfaOBD website.
While AlfaOBD is user-friendly and caters to car owners, it’s packed with features typically found in professional-grade scanners. What sets AlfaOBD apart from generic OBDII/EOBD diagnostic applications is its native support for Electronic Control Units (ECU). Standard OBD2 scanners often provide limited access, mainly focusing on engine and transmission modules, and sometimes ABS. AlfaOBD, however, delves deeper into your vehicle’s systems.
AlfaOBD is available for both Windows PC (XP, 8, 8.1, 10, 11) and Android (OS 4.0.3 and up) platforms. The functionality is identical across both versions, allowing you to choose based on your convenience.
Important Note: Be aware that the “Alfa OBD2 app” on the Apple App Store is not an official AlfaOBD product for iPhones. It is a separate, unrelated application.
For Mac users, the Windows version of AlfaOBD can be used via Parallels or Bootcamp. However, on M1 Macs with Parallels, only WiFi OBD interfaces are compatible. Intel Macs offer more flexibility, supporting USB and WiFi interfaces through Parallels, and Bluetooth/USB/WiFi interfaces when using Bootcamp Windows installation.
Key Features of AlfaOBD:
- Real-time Parameter Monitoring: Monitor a vast array 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 Reading: Access crucial static information such as ECU identification, system status, and diagnostic trouble codes (DTCs). Fault codes are presented with probable causes and freeze frame data where available, providing valuable context.
- Fault Code Management: Clear existing DTCs and actively monitor the system for the occurrence of new faults. This allows you to track down intermittent issues and verify repairs.
- Active Diagnostics and Configuration: Perform active diagnostic tests and configuration procedures for various vehicle components controlled by ECUs. This includes service light resets, oil change procedures, DPF regeneration, ABS bleeding, air suspension maintenance, transmission calibration, and many other advanced functions.
- Electronic Key and RF Remote Programming: On select vehicle models, AlfaOBD enables electronic key and RF remote control programming, offering a cost-effective solution for key replacement or adding extra keys.
- Car Configuration Adjustment (Proxy Alignment): Adjust vehicle configuration settings, enabling activation of newly installed equipment within the Body Computer configuration. This process, known as Proxy Alignment, ensures all modules communicate correctly after modifications or component replacements.
Hardware Requirements for Using AlfaOBD:
To effectively use AlfaOBD with your vehicle, you will need the following hardware components:
1. Security Gateway Bypass (for 2018 and newer vehicles):
Starting with the 2018 model year (and 2017 Fiat 500L), Stellantis (FCA) implemented a Security Gateway Module (SGW) to prevent unauthorized access to vehicle systems. Currently, AlfaOBD does not offer a software bypass solution. Therefore, a hardware SGW bypass module is necessary for diagnostic access on these newer vehicles.
Owners of specific models like Alfa Romeo Giulia/Stelvio, Fiat 500X/Argo/Chronos/Toro, Jeep Renegade/Compass MP, Ducato Serie 8, and RAM ProMaster 2022+ should ensure the bypass module supports the second high-speed CAN bus, which is connected to pins 12 and 13 of the OBD socket.
Recommended SGW Bypass Options:
-
North America:
- zAutomotive – 2018+ Dodge/Chrysler/Jeep – Specifically for 2018 and newer Dodge, Chrysler, and Jeep vehicles.
- zAutomotive – All Stellantis (FCA) Vehicles – Compatible with 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).
- KaodTech – RAM/Dodge/Jeep – Designed for RAM, Dodge, and Jeep vehicles.
- ECRI – 2018+ Jeep/RAM – Bypass module for 2018 and newer Jeep and RAM models.
-
Europe:
- Electronic-Fuchs – Offers a range of bypass solutions.
- OBDauto.fr – SGW Bypass Box – SGW bypass box for FCA vehicles.
- OBDauto.fr – SGW Bypass Cable – SGW bypass cable for FCA vehicles with 8 and 12-pin configurations.
Ensure compatibility with your specific vehicle model by confirming with the bypass distributor or manufacturer if you are unsure.
For guidance on SGW location and bypass installation, refer to resources like:
It is advisable to disconnect the bypass module before taking your vehicle to a dealership, as it may interfere with their diagnostic tools.
2. OBD Interface:
You will need a compatible OBD interface to establish communication between your vehicle and the AlfaOBD software.
Refer to the Supported Vehicles list for recommended OBD interface and adapter options specific to your vehicle model.
AlfaOBD currently supports the following interface types:
- ELM327: A widely available and versatile interface.
- OBDLink MX+ / EX: High-performance interfaces offering enhanced speed and reliability.
- ELS27: Another popular and capable interface option.
- Vgate vLinker FD / FD+ / MC / MC+ / FS: A range of Vgate interfaces with varying features and compatibility.
- OBDKey multipin: A specialized interface with multi-protocol support.
- KLLine USB interfaces: USB interfaces for K-Line communication (Note: Not supported on Android).
- CAN USB interfaces: USB interfaces for CAN bus communication (Supported on Android via OTG).
- WLAN interfaces: Wireless (WiFi) interfaces for connection (Compatibility varies with Android devices).
- Bluetooth interfaces: Wireless (Bluetooth) interfaces for connection.
Note: KLLine USB interfaces are not supported on Android due to OS limitations. CAN USB interfaces are supported on Android devices via USB On-The-Go (OTG). Verify OTG compatibility of your Android device and acquire a suitable adapter if needed.
Note: Some WLAN interfaces, like OBDLink MX+ WiFi, have built-in Android support. For other WLAN interfaces on Android, ad-hoc Wi-Fi support may be required, potentially involving rooting the device and replacing the Wi-Fi driver. Check WLAN interface compatibility for Android use before purchase.
3. Colored Adapters:
Depending on your car model, production year, and OBD interface, additional colored adapters or adapter sets might be necessary.
Consult the Supported Vehicles list for recommended OBD interface and adapter combinations for your specific vehicle.
The AlfaOBD app conveniently displays the required adapter type and suggested OBD interface on its selection screen when connecting to a control module. It also shows a “Connect adapter…” message before attempting connection.
Important Note: When using OBDLink MX+/EX, ELS27, or Vgate vLinker FD/FD+/MC/MC+/FS interfaces, a “blue” adapter is not needed. Simply close the “Connect blue adapter” message and proceed with the connection.
