Hi...welcome to the forum!
Two points that jump out at me from those readings...
1. The vehicle speed is registered at 255kmp? surely not!
2. The voltage at terminal 30 is only 9.0 volts...which would suggest a poor earth, grubby connections or old/defective battery.
I would go back to basics and test the battery, any connections from the battery and to the starter and if the battery is low on discharge test, I would replace it.
Let us know how you get on with it
