John Deere 333G codes DCU 523588.07 and DCU 523636

My John Deere 333G was running fine with no problems on Monday(04/21/22). Used it for a few hours and parked it. Got in it today(04/23/22) and it is throwing two codes. DCU 523588.07(def system fault)and DCU 523636.00. Tried clearing the codes and they just come right back up. Wondering what the easiest and fastest fix was for them. Thank you

    Welcome to HEF Koty ! Serial number would be of great help. Post a picture of the wiring and more specifically, the wire loom at the dosing injector.
