Start-up Long Beep + Airbag Light

[brake checker]

Hello,

Fun one here... Looking for some insight and help. Done some digging on what these might be, but I'm still not sure. Two situations might be related, but most likely not.

Situation 1: On startup car makes this loud beeeeeeep noise. (having trouble uploading video, but could text if someone cares enough) wondering if it is ABS related (See Codes Photos)

Situation 2: My airbag light has been on since I've owned the truck. Just a solid light (no blinking etc.), all steering wheel functions work, so I do not want to point to the clock spring assembly behind the wheel just yet, but some codes B1181(See Codes Photos) point to that?

Nothing crazy, some 2 little gremlins that I want to take care of. Could be crazy if my airbags don't deploy lol...

Thanks.

sounds like your brake booster is failing?

the psqibs on the airbag light are the pretensioners failing/failed. you can take the seatbelts out and send them to a company to have them repaired/refurbished

Brakes have been good, no weird noises from ABS or any other lights. Still on the original unit though...

As far as seat belts, wondering if anyone has done this repair/refurbished themselves?

From some reading up, it might all just be cascading from a Rear Passenger Side Wheel Speed Sensor issue. Going to mess around and see if cleaning the connection helps.
