Problem CEL on P0563 VBU high voltage

-hi i have an CEL on P0563, i already checked on a topic here in the forum and already checked the wiring on the fuel pump and main relay. Everything is connected properly between the relay and ecu.

- i removed the k20a engine from my previous car honda fit GD with the k-pro, all worked fine, there's no CEL. so i think theres no problem with it being a bad ecu.

- is it ok to drive the car having this CEL.

thanks

Try the ECU in a known good vehicle.
