@North Idaho Wolfman will probably better resource here than me.
From what I can find, it seems to me that 2220 was saying there was a communication error with the ECM, then 1830 indicated ECM was not getting sufficient power.
I'd start with checking my fuses, particularly relating to the ECM, and checking for corrosion on battery terminals/ Weak battery.
But I am not an expert here, my tractor was 35 years prior to the ECM era.
