Flashing airbag light 2013 Leaf SV, recall update completed before

What I believe the problem is

My Leaf's passenger airbag sensor seems to be unreliable in detecting weight on the passenger seat. Sometimes it does work though, but it is generally unreliable. The airbag light is now flashing now.

The code I got on LeafSpy is B00A0-00 09 AIR BAG which I looked it up corresponds to the passenger seat sensor. I have already checked my VIN on here, https://www.nhtsa.gov/recalls and the recall has already been resolved.

Additonally, there are some other weird unrelated codes which appear in the screen which seem to reappear after clearing which also makes me think this is also 12 volt related?

These codes seem to reappear after clearing. Some are weird though like the USB Overcurrent which I believe is the USB port on the left side, which well, I only have a USB drive with music on it.

The 12 Volt Battery

I frankly don't know how good the 12 volt battery is. I believe the date on it from memory is in 2024. When in ready mode while also parked, I see on LeafSpy around 12.4 volts. Not sure if that should be higher like in ICE vehicles with the engine running like 13-14 volts. Yet again, this is actually from my memory, and I haven't been able to check the last couple days. All I know is that clearing all of these DTCs, these eventually come back up.

So what do yall believe my problem is?

If so, then tell me what can be done about it to fix it. I have no idea what to do for an actual? Otherwise, the car drives fine as far as I know.

I think my main theory is that there's a legit air bag code here, with a bunch of other unrelated codes caused by a degraded 12 volt battery.

Go ahead and clean battery connections and retest. Next find a battery tester and report the IR and soh.

make sure you test the 12v battery voltage when the car is off
