LS MT125
When trying to start the engine won't turn over. It reports 4-1 over u001 on the display.
I took out the battery. It has a green light on top and measures just under 13 volts.
Does anyone have the service manuals or error code list?
Same tractor as MT122 with more horsepower.
Someone on the LS service group had this question (Google shows me part of the question) I requested access and will check there when I get approved.

It was the battery. It measured at 13 volts, but after charging it the tractor started right up.

Replace the battery or you'll have the same issue again. Some batteries last, some don't. 13 volts isn't enough, you need 14 standing.
