I think you mean 2D?
2D is field current senser out of range. Could be bad connection at power card, broken sensor...this is a plastic loop that is mounted to heat sink. power cable goes through it. Check for shorts to ground first. Remove heat sink and check for holes in insulator. A small hole causes short or arcing to frame.
