Looking help with electronic power system??

Hello,

Last night, while driving, the EPS light came on and car kinda lost power. I stopped at a gas station, turned the car off and back on again. The light was gone. But when I read the manual it said that after the light comes on the car runs on a backup system. Do I need to do anything else now that the light is off? Maybe not the best idea to make it that complicated, but taking some inspiration from that would be cool in my opinion.

So let me know what you think and why!Please share any more information if anyone can and even a Power System Video will help.

Any help will be appreciated.
Thank you.
