Are you a proud owner of a vehicle from the Stellantis group (formerly Fiat Chrysler Automobiles – FCA)? Do you want to take control of your car’s diagnostics and maintenance beyond the basic OBDII scanners? Then the Alpha Obd2 App is the tool you need. Specifically designed for vehicles from 1994 to 2023 (Fiat, Alfa Romeo, Lancia) and 2005 to 2023 (Chrysler, Dodge, Ram, Jeep), this software offers in-depth access to your car’s Electronic Control Units (ECUs), going far beyond generic OBDII applications.
While standard OBD2 scanners provide limited information, primarily focusing on engine and transmission issues, the Alpha OBD2 app dives deep into various modules, including ABS, body control, climate control, and more. Available for both Windows PC (XP, 8, 8.1, 10, 11) and Android (OS 4.0.3 and above), the Alpha OBD2 app provides consistent functionality across platforms, making it a versatile choice for car owners and even professional mechanics.
Important Note: Be aware that there is an “Alfa OBD2 app” on the Apple App Store, but it is not the AlfaOBD version discussed here. It’s a completely different product unrelated to AlfaOBD. For Mac users, the Windows version of the app can be run through Parallels or Bootcamp. Note that on M1 Macs with Parallels, only WiFi OBD interfaces are compatible, while Intel Macs with Parallels support USB and WiFi. Bootcamp installations on Intel Macs support Bluetooth, USB, and WiFi OBD interfaces.
Key Features of the Alpha OBD2 App
The Alpha OBD2 app is packed with features to empower you with comprehensive vehicle diagnostics and control:
- Real-time Parameter Monitoring: Monitor a wide range of dynamic parameters from your engine, transmission, body, dashboard, ABS, climate control, and other systems. Visualize this data through customizable graphs and plots, allowing you to track performance and identify potential issues.
- Static Data Reading: Access crucial static data such as ECU identification, system status, and diagnostic trouble codes (DTCs). The app provides detailed fault code descriptions, potential causes, and freeze frame data where available, giving you a complete picture of any stored errors.
- Fault Code Management: Clear existing DTCs and continuously monitor your vehicle for the appearance of new faults. This proactive approach helps you stay ahead of potential problems and maintain your car’s health.
- Active Diagnostics and Configuration: Perform active diagnostic tests and configuration procedures for various systems controlled by ECUs. This includes service light resets, oil change reminders, DPF regeneration, ABS bleeding, air suspension maintenance, transmission calibration, and a wealth of other functions.
- Electronic Key and Remote Programming: On certain vehicle models, the Alpha OBD2 app allows for electronic key and RF remote control programming, offering convenience and control over your vehicle’s security features.
- Car Configuration and Proxy Alignment: Adjust your car’s configuration, enabling the activation of newly installed equipment within the Body Computer configuration. The Proxy alignment feature ensures all modules communicate correctly after configuration changes.
Hardware Essentials for Using the Alpha OBD2 App
To utilize the Alpha OBD2 app effectively, you’ll need specific hardware components:
1. Security Gateway Bypass (SGW) for Newer Models (2018+)
Since 2018 (and 2017 for Fiat 500L), Stellantis (FCA) vehicles have incorporated a Security Gateway Module (SGW) that restricts unauthorized diagnostics. Currently, the Alpha OBD2 app doesn’t offer a software bypass solution. Therefore, a hardware SGW bypass module is necessary for these newer vehicles.
For owners of Alfa Romeo Giulia/Stelvio, Fiat 500X/Argo/Chronos/Toro, Jeep Renegade/Compass MP, Ducato Serie 8, and RAM ProMaster 2022+, ensure your chosen bypass module supports the second high-speed CAN bus, connected to pins 12 and 13 of your car’s OBD socket.
Here are some recommended SGW bypass options:
North America:
- z Automotive 2018+ Dodge/Chrysler/Jeep Bypass
- z Automotive All Stellantis (FCA) Vehicles Bypass
- KAODTECH Security Module Bypass
- ECRI Security Module Bypass 2018+ Jeep/Ram
Europe:
Always verify compatibility with the bypass distributor or manufacturer if you choose an alternative bypass. For guidance on SGW location and bypass installation, refer to resources like:
It’s advisable to disconnect the bypass before visiting your dealership, as it may interfere with their diagnostic tools.
2. OBD Interface
You’ll need a compatible OBD interface to establish communication between your vehicle and the Alpha OBD2 app. Refer to the Supported Vehicles list for recommended interfaces and adapters for your specific car model.
Currently supported interface types include:
Note: KL-Line USB interfaces are not compatible with Android due to OS limitations. CAN USB interfaces are supported on Android via On-The-Go (OTG). Ensure your Android device supports OTG and acquire the necessary adapter.
Note: Some WLAN interfaces offer built-in Android support, such as OBDLink MX+ WiFi. WLAN connectivity for other interfaces on Android may require ad-hoc Wi-Fi support, potentially needing device rooting and modified Wi-Fi drivers. Verify WLAN interface compatibility with Android before purchase.
3. Colored Adapters
Depending on your car model, production year, and chosen OBD interface, you might need additional colored adapters. Consult the Supported Vehicles list for specific adapter recommendations.
The Alpha OBD2 app conveniently displays the required adapter type and suggested OBD interface on its selection screen before connecting to a control module. It also shows a “Connect adapter…” message when necessary.
Important: No “blue” adapter is needed when using OBDLink MX+/EX, ELS27, or Vgate vLinker FD/FD+/MC/MC+/FS interfaces. Simply close the “Connect blue adapter” message and proceed.
“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
Adapters are available from various suppliers, including:
- Electronic-Fuchs.de
- Obdauto.fr
- Gendan.co.uk
- Amazon and eBay
