I get a 121 error when cell is reversing. No error when cell is in normal mode. If I reverse the DC cable, I get a 120 error when the cell is in normal mode, and no error when the cell is reversing. I'm not sure if this is a cell issue or a board issue. Any help is greatly appreciated.

As an FYI, removed thermal regulator and all was well. Replacement ordered.

Just to clarify, the regulator was the only part replaced. You did not replace HLS or AGS.

I have the same issue, but not sure which switch is which. On the attached diagram, from what I've read, the HLS is either 5, 6, or 7. Was it easy to replace?
