"Stop Car, Leave running" came on the screen?

"Stop Car, Leave running" came on the screen with a battery symbol. I figure it needs a new battery. My question: Is the computer resetting something I can do after installing the battery? The dealer wants $650 but the battery is $170 at Costco. Almost $500 to reset battery. Ridiculous. Is there a link I can follow or instructions you can provide to reset the computer?

I am including a screen shot of a diagnostic from Auto Zone, might this play into the "Stop Car?" I am going to replace the plugs and ignition coil in a few days. Also, Battery Voltage read 14.77, they said it was still good.

Thank you so much.
