Ethernet Communication
WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
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 TCU and the GWM and other connected modules such as the APIM and IPC 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.
