Codes A3, 54-1, 64-1 - Technical Troubleshooting discussion in Forkliftaction's forums

Toyota 7FBCU25:
Codes A3, 54-1, 64-1

I have a 7FBCU25/70823. 48V system

The truck was originally throwing a F1 code, swapped the CPU board with a known good board. Now I'm getting codes A3, 54-1, 64-1 and truck has no functions. When you cycle the key "on" it doesn't pull in the line contactor or anything. A3 is saying incorrect voltage, but the board I swapped it with was also a 48V truck. It will not allow me to get into the dash menu. Any help is greatly appreciated.
