Description And Operation: Description
The SGW module is a security hardware device located behind the radio to stop unwanted access and threats to the Controller Area Network (CAN) for the vehicle. The SGW module does not contain any drivers and therefore does not directly operate or control any vehicle components.
The complexity of vehicle networking has led to the development of a variety of bus standards and protocols that are specific to their communication domains. The SGW module serves as the information bridge between these communication domains and the diagnostic scan tool and the radio. Hardware security features of the SGW module are used to prevent unauthorized bus network access.
The SGW module is flash programmable. Failure to flash a newly installed SGW module will leave it in a locked mode. When in the locked mode, the SGW module will not operate.
