My wife has a 2002 Honda Civic EX and the SRS light has come on. From what I've read, the SRS light has to do with the seat belt tensioners or the airbags. I've found a couple TSBs that might address my problem.

TSB# 020103
SRS INDICATOR ON WITH NO SRS DIAGNOSTIC TROUBLE CODES (DTC) SET. *TT *JB
If you know a link to this actual TSB in PDF that would be great!

TSB# 06-009
Warranty extension OPDS Unit or OPDS Sensor Triggers SRS DTC(s) 15-1, 15-2, 15-3
Also, here's a link I found to the actual TSB for this one...

It seems like if there are SRS diagnostic codes present, I might be able to have this covered under an extended warranty. But if no codes are present, I might be SOL. How can I find out if SRS diagnostic codes are present? I only have an OBD-II code reader. Would AutoZone be able to read this for me?
Money is kind of tight right now and I'd really hate for Honda to bend me over right now.

Autozone will get the codes and print what they mean and possible resolutions.

Your reader should be able to get the codes, but possibly not an explanation.

Hondas and Acuras have the SRS issue coming up in their 2000 - 2003 models.

Mine, especially, is due to the internal neon lighting system I installed... do you have anything plugged into the electric socket?
