Angry SRS Light Constant ON!

Today I was leaving the grocery store, and I noticed my SRS light was on... and it didn't turn off! I stayed in the car for about 5 minutes hoping it would turn off (lesser malfunction when only on for temp time at startup)... so I have a constant SRS light now! Everything else is fine with the car.
I do have one thought though... about 1/3 of the time, when I engage the rear defroster, the light flashes, indicating a low voltage.. it always will come back on (steady) a few moments later. My chargine system seems just fine though... along with my really new MB battery. No other low voltage/no starting symptoms whatsoever. Well I decided to check out my owner's manual, and it said that low voltage could trigger the SRS light.
My question, how low must the voltage go for the SRS system to detect a malfunction? My ABS light is not/nor was on at all. So if this is the case, I'm thinking that the voltage would have to be the min voltage that the ABS needs to function properly.
I hope that made sense.. thanks!
