The GWM serves as the programming manager for over the air software updates completed for target modules. Depending on the modules involved the gateway module may store the update or just relay the update to the target module. The gateway module acts as a router or hub for the Ethernet networks and is also connected to the vehicle CAN. Software updates can be deployed from the GWM to target modules using either CAN or Ethernet networks.
The GWM requires PMI when replaced.
