Yellow airbag/seatbelt warning light illuminated and then went out, what may cause this?

If the airbag it's been deploy , check the crash sensor , if comes on during driving, some cars the seatbelt on passemger side its integrated , disconnect the batter before you go messing with it, depending on year make model, autozone will scanned it and can turn it off, if after a drive cycle comes back on,check crash sensors seatbelt plugs, or plugs on the airbags itself.hope this helps

Ignition switch or the prove out circuit control that times the lights off may be bad.

It will need to be scanned by a shop. Most common problem is the passenger occupancy seat mat.

Pull the fuse it won't affect the seatbelts from working correctly. otherwise you have to disconnect each seatbelt lock to find the defaulted lock. As for the airbag light; do you have the type that can be turned off with a key? It may be permanently turn off and needs to be turned back on with the key.

You need to replace the airbag control module, it is a one time use device.

check your seat belt stork , check wiring to stork ,

yes, you can use the a home remedy to reset it, this tool may be help.

the seatbelt light/warning illuminates only if driver has not buckled up also the belts are pretension if car has front impact along with air bags so may i suggest that you check under front seats that the wires for seatbelt actuation have not come loose ?either at plug or the belts lockup at side of seats check also for damp on carpets this too causes elec/s malfunctions

the red one i belive is your seatbelt warning..... put on your seatbelt it should go out... the yellow may be the check engine light.... stop in at your local autozone and have them read the codes (free) and write down what they are and post them here.. they will probably tell you too what the problem might be ... i'll have a look for the user manual too.
