FCA SGW (Secure Gateway) Access

What Is FCA SGW Access?

FCA vehicles (Fiat Chrysler Automobiles) use a Secure Gateway (SGW) module — introduced in 2017 — to prevent unauthorized diagnostics and security attacks. Without authorized tools, diagnostic capabilities (including bi-directional testing and DTC clearing) are restricted. The SGW must be unlocked by an authenticated diagnostic tool.

FCA US now manages access via Automatic Authentication Authority (AutoAuth).

Bi-Directional Control (Active Test) — Lifetime Free Update
