My Aria won't start.

It showed several errors on the display glowing yellow and turned off after a few seconds. When the screen went off, it remained glowing yellow "Servo control problem"
He did all this three times and I left the car.
I came back after 30 minutes and everything was fine.
I was wondering if there is a way to reboot the system as this seems to be a software bug?

Most of these odds behaviors are on most cases due to a faulty or near faulty 12V battery that messes up the systems.
The only way to do a full reboot is disconnecting the 12V for a few minutes and connecting it back.
