M126X won’t start. Showing E-ENG and specific code 1830. Initially would crank and was showing code 2220, now won’t crank and showing 1830. Any guidance appreciated.

@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.

Start by pulling the battery and having it load tested.
Then check both ends of both battery cables.

Check back on what you find.
