2013 Honda Civic LX got a flat and put donut on drove 10 miles to get replaced. Got home and saw check tire pressure light on dash. So, I scanned the car and got the 2 codes below. I disconnected the battery and rescanned, but the codes are still there, battery voltage when off was 12.2 and when running was 12.9 and tire pressure is correct. I charged battery and the 85-01 code no longer appears but still have 71-11 code. My guess is the battery is on its way out but before I buy new battery any thoughts on these codes? Thanks !

You are on the right track; I would get the new battery and then clear the codes or do a hard system reboot to help clear the modules. This guide can show you how:
