I did a search on SRS light staying on, but only found examples of older models...anyone have any experience with an '03 SRS light staying on?

I'll put it on a computer later in the week, but am I going to be looking at the same two codes that it seems to throw for older model years? If the problem is a low voltage issue, what is the fix for this? Is it a weak battery or do they seem to be losing the voltage somewhere in line? Everything else seems to be working fine, so I'm guessing the voltage may be getting lost in line and not from the battery???

Thanks for any advice anyone might be able to offer
