My girlfriends 04 honda civic ex has problem with seatbelt sensor problem it keeps beelping and light still come on when we are buckled up, I checked the wiring under seat and there were 2 wirling there and they both are plugged I tried to figure out which one it was I unplugged the yellow plugs and airbag light came on in the gauge and I plugged it back in it won't go off and I umplugged the grey plugs and seatbelt light came off I rather it to be unplugged because it make so much noise and soo annoying while we were driving it and still buckled up so we got tired of hearing it annoy beeps so I'm trying to get airbag light go off?

 

Check with a dealer. I think there is a lifetime warranty on seat belt related systems.

Disconnect the battery, plug everything back in properly then reconnect battery. Hopefully that will reset the airbag light. Don't tell the dealer that you were unplugging stuff of course.
