2010 Prius with error codes B1826 and B1821

Bought a 2010 in Feb, for uber purposes. Now, thanks to covid (and elderly person lives with me), I feel I shouldn't be driving uber right now, so I'm selling it.

The car has given me ZERO issues and I like it, but I don't need two cars. So, I'm all ready to sell it, have it sitting in my yard for the "FOR SALE" sign, a few have looked at it, all have liked it. It's clean and no issues.

I did have a dash cam set up, with the wire going in the upper part of the windshield, down the passenger side door frame (just inside the weather strip), behind the glove box and plugged into the power outlet.

All of the sudden, the SRS light comes on and stays on! Wth? I took it to my brother, who's a mechanic (but has never worked on Prius, neither have the guys at his shop), he plugs in his gizmo and we get the error codes B1826 and B1821. Obviously it's the airbag system. So we did a quick google search and several people said to unplug the wire harness.

He unplugged the wire harness under the passenger seat and plugged back in, we still have the code.

He hasn't had time to dive deep into it so I'm trying to do some leg work to see if this is an easy fix.

I've read countless articles and posts, but haven't seemed to find out what the fixes for these error codes are. Can someone help? Or at least direct me to a place where it can find out how to fix it?

I can't believe it's anything major as the car has hardly moved in the last week or so. Just, all the sudden, those error happen. HELP!

 

Well, this was strange......

I read somewhere that if you drive the car for a while (which it hasn't been driven more than 1/2) in the last week, that the warning light might go away. So, I went out go for a longer ride, started the car, and the light went out! LOL! I guess something fixed itself. Keeping my fingers crossed it won't happen again!
