why does the check airbag warning light come on in my toyota corolla 2010

Hello, You have an error somewhere in your SRS (airbag and seatbelt) system. You will need the vehicle scanned to identify the failure, and that system should be serviced by a professional. If an occupant position sensor needs to be replaced, you could do this yourself, but you may still need to have the dealer reset the airbag light for you.
