5 CANbus Communication Troubleshooting
The CANbus network health is indicated on the Home screen via the CANbus status icon.
Figure 5.1 CANbus Status Icon
When the icon indicates a network fault (red), view the network status screens to determine which devices on the network are
not communicating. The mode will indicate Comms Fail. If these devices are not intentionally powered off or not intentionally
disconnected from the network, check network cabling and CANbus configuration.
