In 2018, the Security Gateway Module (SGW) was implemented by FCA USA to prevent unauthorized access. FCA said that SGW was developed to limit "the ability of non-registered and non-authenticated users to perform intrusive diagnostics such as bi-directional controls", so users cannot directly clear the DTC, as well as any bi-directional control test (including actuation, relearn and calibration) on vehicles equipped with SGW.

Xtool users can now access the SGW module and perform previously restricted operations simply by registering with the authentication service AutoAuth, without requiring additional accessories. Users can register via AutoAuth's web-based registration portal, selecting the desired package. Then add the Xtool diagnostic tool.

Xtool will release the software to specific professional diagnostic tools in the North American market that have subscribed to the software. Users whose subscription period has expired can renew their subscription through their authorized Xtooltech reseller to update the FCA software.
