Have heard low battery can cause gremlins, what is the state of the battery now you've jump started it
Did it go flat because its old and near end of life.
Is there any option of swapping in a known good battery and seeing if that makes any difference
Can you try taking it out and properly charging it while leaving car without battery for a while. You might find on reconnecting it the faults go away
I messed around with mine one time and ended up with a Christmas tree dash, throttle errors, abs, srs, all sorts.. Disconnect 1hr, reconnect, back to normal
If nothing else it doesn't cost you anything to try it. Key in pos2 for reconnect to allegedly stop airbags blowing or causing other issues
AUM is audio module, if you've upgraded to a better head unit you'll probably have to just live with knowing that fault exists, me too
Also generally best to say what the car is, model, age, etc
