Secure Gateway (SGW) Support
Perform Full Diagnostics without Restrictions


What Is a Secure Gateway (SGW)?
A Secure Gateway (SGW) is a cybersecurity system installed by vehicle manufacturers to protect critical vehicle networks. It functions like a firewall, restricting access to certain control modules unless the technician is properly authenticated. On SGW-equipped vehicles, advanced diagnostic functions—such as coding, bidirectional controls, and module adaptations—may be limited without authorization.


Why Do Diagnostic Tools Need Secure Gateway Access?
Many vehicle manufactuers now require aftermarket diagnostic tools to authenticate through their official Secure Gateway systems before advanced diagnostics, service functions, coding, or programming can be performed. Without authentication, access to these functions remains restricted.
