Ethernet Module Communications Network - System Operation and Component Description: Overview

The Ethernet communication network is a high speed communication network providing high bandwidth data transfer and improved data security to support module updates over the air, driver assistance systems, multi media systems and improved connectivity. The Ethernet communication network connects the GWM to the TCU, the APIM and other connected modules, dependent on the vehicle configuration.

The network is primarily utilized for the update over the air feature to quickly and securely transfer data from the connected external source (data cloud) through the TCU to the GWM where it is distributed to the receiving module on the vehicle.
