C30 Electrics : - Alarms V30

Good day Gentlemen
My daughters C30 SD 2009 developed an electric problem a few weeks ago, diagnosed as the ECU at fault, the alarms showing and flashing are the AntiSkid, ABS and brakes. also the wipers tend to come on erratically?
I removed the ECU and sent for testing and it came back as 'no faults found'.
Today, i refitted the ECU, started the car and let it run for ten minutes, all seemed ok, then I took the revs to 2200 and suddenly everything started flashing again. I took the revs a little higher then removed my foot from pedal and for a fraction the revs still increased.
Once revs back to tickover the alarms disappeared.
Another thing I noticed is the LCD readout, for radio etc is flickering, even at tickover, increasing revs makes no difference.
My suspicion is the increased engine revs cause vibration and maybe a loose connection is causing problem.
Any ideas would be welcome?
Thank you in advance gentlemen
