AutoAuth Secure Gateway Process
In 2018, Fiat Chrysler Automobiles (FCA US) (now Stellantis) implemented the Secure Gateway Module. This security feature protected many of the on-board control modules against security breaches by placing them behind a firewall. To access the Secure Gateway Module and perform required services, the diagnostic scan tool must be approved and certified by FCA US.
Hunter Engineering Company has worked with FCA US to provide independent shops and their technicians the ability to work within these security features and perform the necessary diagnostic procedures on FCA vehicles.
