FCA Bypass SGW – Gain Full Access to Your Car's Diagnostic System
Vehicles from the FCA Group (Fiat Chrysler Automobiles) have been equipped with a security feature called SGW – Secure Gateway since 2018. This is a digital barrier that restricts access to the car's control system via the OBD2 port. To perform advanced diagnostics, coding, and service resets, an FCA Bypass SGW module or cable is required.
With an SGW-bypass for FCA, you get full access to the car's communication network, allowing you to use your own diagnostic tools – without being forced to go to an authorized workshop.
What is SGW and why does it exist?
🔒 SGW (Secure Gateway) is a security module that protects the car's internal CAN bus from unauthorized access via the OBD2 port.
🛠️ This means that even if you can read some fault codes, important functions such as:
-
Clearing fault codes
-
Service reset
-
Live data
-
Adaptations or coding
✅ The solution is an FCA SGW Bypass – a physical connection that temporarily bypasses the SGW module and allows you to work freely with your tools.
When is an FCA SGW Bypass needed?
You need a bypass if you have a Fiat, Jeep, Chrysler, Dodge, Ram, or Alfa Romeo from 2018 onwards and want to:
-
🔧 Perform full troubleshooting
-
🔄 Reset oil service
-
⚙️ Program or code settings
-
🧠 Use advanced apps like AlfaOBD or Multiecuscan

How does FCA SGW Bypass work?

When the bypass is connected, full communication between your OBD2 device and the car's control system is allowed.
💡 No reprogramming is often required – it's "plug and play," but should only be used during active diagnostics.

✅ AlfaOBD (Android/Windows) – recommended for Fiat, Jeep, and Dodge
✅ Multiecuscan – primarily for Fiat and Alfa Romeo

Frequently asked questions
Is it safe to use a bypass?
Yes, as long as you use it temporarily and only during diagnostics or coding. The SGW protection should be restored after use.
Should I use a 12+8 adapter or an internal cable?
12+8 is easiest – no disassembly required. However, some models require a direct connection to the SGW box.
How do I know if my car has SGW?
If the car is FCA and manufactured in 2018 or later, it almost certainly does. Some apps (e.g., AlfaOBD) can also show SGW status upon connection.
Can I leave the bypass installed permanently?
It is not recommended. SGW exists for security reasons. Use it only when needed, then restore the original connection.
