These are communication error codes in the CAN and LAN circuits. It could be a loose or bad ground, weak ground, bad battery or alternator or one of the modules is having issues.
Check the amperage output of the battery.
Check ground conductance between battery and engine block, battery and body and battery and firewall.
Check the alternator output and performance.
If those check good, follow the chart attached. If you find something that leads you to check something off the chart, let me know and I'll post that chart.
