Discussion:
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.

Fact of the week
The two internal cavities in our nose called nostrils function as separate organs. Each nostril has its own set of turbinates and olfactory receptors. The two independent organs work together through a mechanism called the nasal cycle, where one nostril is dominant for air intake while the other rests and is better at detecting scents.
