Cutter offsets use the same table as tool length offsets just different offset numbers as stated above.
Try placing the D offset code in the line with the G41 (which I believe is normal programming practice) and not in the same line with the H length offset code.
I've found some of the Fanuc T controllers need an F code somewhere near the start of the program before a G1, but haven't come across that with any Fanuc M controllers yet.
