Network Message Chart
The displays that appear on the HUD are based on messaged inputs to the HUD module from the IPC or other network modules. The HUD module and the IPC communicate on the HS-CAN3. If the originating module communicates on a network other than the HS-CAN3, the messaged signals will be sent to the GWM first, then to the HUD module.
