Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Ethernet Communication
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.
