92 Accord SRS light on

My 92 has the SRS warning light on. Although it's an old car (21 years old, 230K miles), it's still very strong and would like to keep it.

Anyone knows how to diagnose/trouble shoot? Thanks.

It could be the drivers side seat belt switch. From what I've read on other forums the seat belts are covered by lifetime warranty. There is a way to read the SRS code to get closer to the problem, but it is a special reader. Not a OBD-II reader. I don't know if part stores have them to borrow, never had to use one.
