Hello everyone I'm new to the site, looks like an excellent source of information, I hope to get help with my problem. I recently installed a new battery in my 1992 toyota camry and now the (air bag ) light stays on, any advise? Thank you.

The code just needs to be cleared. With that said, it's not easy to clear. It has to be done at the dealer with a service tool used to clear these early airbag codes.
You should have code 22 which is a power interrupt code.
