Autel’s FCA AutoAuth solution is a critical tool for technicians working on 2017+ Chrysler, Dodge, Jeep, Fiat, and other Stellantis (formerly FCA) vehicles—unlocking restricted diagnostic functions blocked by the vehicle’s Secure Gateway Module (SGW). Below, we break down what FCA AutoAuth is, why it’s essential, and how to use it with your Autel scanner to restore full diagnostic capabilities.
Ⅰ. What Is FCA AutoAuth?
FCA AutoAuth is a secure authentication service developed by Stellantis (formerly FCA) to regulate access to modern vehicle networks. Think of it as a digital credential that allows your Autel diagnostic scanner to bypass the SGW—a built-in security “firewall” installed on most 2018+ FCA vehicles to prevent unauthorized access to critical vehicle systems.
Without AutoAuth authorization, you’ll be locked out of core diagnostic functions for FCA vehicles, including:
- Clearing Diagnostic Trouble Codes (DTCs): Removing error codes from vehicle modules
- Bi-Directional Controls: Testing actuators, solenoids, and other components in real time
- Module Programming & Calibration: Relearning or coding ECUs, ADAS systems, TPMS, and more
- Advanced System Scans: Full access to powertrain, chassis, and body control modules
Ⅱ. Why Do You Need FCA AutoAuth for Your Shop?
FCA implemented the SGW to protect vehicles from cyber threats and tampering, but this security measure also restricted access for independent repair shops and technicians. AutoAuth solves this problem by providing a compliant, official way to access restricted systems—ensuring you can service late-model FCA vehicles without limitations. All Autel MaxiSYS series scanners (including Ultra, MS909, and MS919) are fully certified for FCA AutoAuth compatibility.
Ⅲ. How to Set Up & Use FCA AutoAuth with Autel Scanners
Getting started with AutoAuth is straightforward and only requires three key steps:
- Create an AutoAuth Account: Visit the official AutoAuth portal at https://webapp.autoauth.com to register your shop/technician profile. The annual subscription starts at $50 for up to 6 users, with additional users costing $2 each per year.
- Link Your Autel Scanner: Once your AutoAuth account is active, add your Autel diagnostic tool’s serial number to your profile. This links your scanner to the AutoAuth service and enables SGW communication.
- Update Your Scanner Software: Autel automatically pushes SGW access software to North American market scanners with active Total Care Program (TCP) subscriptions. If your subscription is expired, renew it through an authorized Autel dealer to unlock AutoAuth functionality.
