A9AC CODE intermittent voltage spikes

So far i replaced voltage regulator and that didnt work

so i got a loaner battery from interstate while they test mine (tested good) that didnt work

I just repalced the alternator and im still getting this code and the symptoms i have are annoying

Radio screen flashes and music pauses then i get dsc malfunction for this all last between 1-3 seconds per episode

Car fires right up and drives smooth i check my battery cable to make sure its secure and its good i also checked the battery strap and its not torn.

If anyone has any idea what could be happening please leave a comment thank you for your help.
