The Secure Gateway (SGW) module in Fiat Chrysler Automobiles (FCA) vehicles, implemented since 2017, safeguards against unauthorized access and potential security breaches. This module restricts diagnostic capabilities, requiring authorized tools and authentication to perform functions like bi-directional testing and clearing Diagnostic Trouble Codes (DTCs). This article explains how the Fca Gateway works and how to unlock it using approved diagnostic tools.
Understanding the FCA Gateway and AutoAuth
The FCA gateway acts as a gatekeeper, preventing unauthorized access to the vehicle’s critical systems. To gain access, technicians need to utilize the Automatic Authentication Authority (AutoAuth) system. AutoAuth manages user accounts and grants access to FCA SGW-equipped vehicles.
For shop owners, this involves registering as a technician and then registering their shop for an annual fee. This membership allows for multiple users and scan tools under a single account. Technicians can create free AutoAuth accounts and link them to their shop’s membership, enabling them to use the registered tools. This system applies to FCA vehicles in the United States, Mexico, and Canada.
