Air bag light flickering

Hey all..I have a 1994 F-150 4x4 single cab truck. The air bag light was coming on and giving a code 12, which I know is low battery voltage..But recently it air bag light will flicker and be accompanied by a buzz, or what sounds like ham radio interference..
No codes, just a flicker. It does this for a couple minutes, then goes away and doesnt come back on..
I'm gonna check my grounds and all connections I can get to..Has anyone else had this issue?

The control module itself can go bad, but checking the connections and grounds is always a good place to start.

My initial reaction was the control module..but now the flickering has me questioning connections. Do you know if the buzz is a by product or is that usually associated with these air bag light issues? Perhaps there are more issues going at once?

If I recall the system is supposed to be able to chime... or beep as a secondary way to indicate trouble. But no buzzing...
