EEP2 error, speedo over read & ECU warning light

[usernothername]

Only other nugget of information gleaned is the live readouts. These look OK as a photo but actually on the first screen the circuit 1 sensor would jump around a bit from -0.27 to +0.36 and the yaw rate would also flicker around a bit. On the second screen the voltage would flicker, dropping from 9.9 to zero for a tiny fraction of a second. it seems to me unlikely that both the brake pressure sensors and the yaw sensor have given up at the same time, so maybe all related to the power <9v error, maybe a loose connection somewhere?

Yes, looks like so... Worth checking ground point locations maybe?
