A SGW Bypass (Secure Gateway Bypass) is an important component for those who want to perform advanced troubleshooting, service reset, or programming on modern vehicles from brands such as Fiat, Chrysler, Jeep, Alfa Romeo, and Dodge. These cars are equipped with a Secure Gateway (SGW) module, which restricts access to the vehicle's control system via the OBD2 port.
With an SGW Bypass cable or module, you can temporarily bypass this lock and use third-party diagnostic tools such as AlfaOBD, Multiecuscan, Autel, Launch, and ELM327 – without being stopped by the car's security system.
What is SGW and why is a bypass needed?
🔒 SGW stands for Secure Gateway – a security module that FCA (Fiat Chrysler Automobiles) began implementing in its cars from approximately 2018 onwards. It protects CAN bus communication between the car's modules and the OBD2 port to prevent unauthorized access.
🛠️ The problem?
SGW only allows limited communication with the vehicle if you use a regular code reader or ELM327 adapter. You can often read fault codes – but not clear them, reset service intervals, or perform coding.
✅ The solution: SGW Bypass
By connecting a bypass module directly to the SGW connectors in the car, you get full access to the car's control system via OBD2 – just like before SGW.
For which car brands is SGW Bypass needed?
SGW is used by vehicles from the following brands:
-
Fiat (500e, Ducato, Tipo, Panda, etc.)
-
Jeep (Renegade, Compass, Cherokee, Wrangler)
-
Chrysler
-
Dodge
-
Ram
-
Alfa Romeo (Giulia, Stelvio, Giulietta)
✅ If your car was manufactured from 2018 onwards, it is very likely to have SGW and therefore requires a bypass module for advanced diagnostics.
Common uses for SGW Bypass
-
🔄 Erase fault codes from engine, ABS, airbag, etc.
-
🔧 Reset service indicator or oil change interval
-
⚙️ Code comfort functions (e.g., DRL, locks, lighting)
-
🔍 View live data from engine and sensors
-
🛠️ Adapt ECU or perform software updates (depending on the tool)
How does the installation work?
An SGW bypass module connects directly between the car's two CAN cables, often behind the dashboard where the SGW box is located. There are also adapter cables with 12+8 pin connectors that can be easily plugged in between the car's OBD port and the diagnostic tool – without you needing to disassemble the interior.
🔧 Step-by-step:
-
Turn off the ignition and disconnect the car's battery
-
Locate the SGW module (usually behind the steering wheel or in the fuse box)
-
Disconnect the SGW and connect the bypass adapter in its place
-
Reconnect the battery
-
Connect the diagnostic tool via OBD2 – now you have full access
-
Don't forget to restore the original connection afterwards
💡 Some models use 12+8 adapters that make installation easier – you don't have to open panels.
Important considerations
⚠️ SGW Bypass should only be used temporarily during diagnosis or programming. After the procedure is complete, the car's original connection should be restored to preserve the security function.
⚠️ Only use with compatible software and devices. Examples:
-
AlfaOBD (for Fiat/Jeep/Alfa)
-
Multiecuscan
-
Autel/Launch (with SGW bypass support)
-
Forscan for some Chrysler/Jeep models
