I just finished swapping a 06 l59 into my 99 suburban. I wrote a base tune for it and it fired up no issues. I walk inside to write a new tune on my desktop and get a 0684 error code when I went to flash it. I left the key on while inside writing the new tune so the battery almost died. Before hooking up the V2 I put a charger on it. What gives?
