Module, Security Gateway (SGW): Operation

WARNING: This page is about a different car, the 2020 Chrysler 300 and 2019 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

The Security Gateway (SGW) module, located on the Controller Area Network (CAN) architecture between the Data Link Connector (DLC), telematics module and the radio, prevents threat to the CAN bus systems through the DLC and the radio access points. A secure connection must be present to allow authentication between the SGW module and the diagnostic scan tool. The SGW module contains up to eight dual wire CAN bus channels that comply with the industry standard CAN-Flexible Data-rate (CAN-FD) bus architecture. The SGW module does not support partial networking functionality. Since the SGW module is a frame gateway, it also does not provide signal gateway functionality.

For diagnostics of the SGW module. Refer to COMMUNICATION - NON-DTC BASED DIAGNOSTICS .
