This code is FU9 open circuit or M1 (traction motor) circuit open.
Check the FU9 which is located on the front wall of the power unit. Should be 3 250A fuses next to each other, it is the far right of the three. If that fuse is good check the Emergency Disconnect Contactor/Tips. Lastly check for an open circuit between battery positive, ED tips, FU9, and Access 3.
