1. Disconnect the battery. This will clear the error codes from the airbag module and turn off the airbag light. To do this, open the hood of your car and locate the negative battery terminal (usually marked with a "-" sign). Use a wrench to loosen the nut that holds the negative battery cable in place and remove the cable from the terminal.
2. Wait for a few minutes. This will allow the airbag module to reset.
3. Reconnect the battery. Reattach the negative battery cable to the terminal and tighten the nut.
4. Start your car and check the airbag light. The light should now be off.
If the airbag light is still on, there may be a more serious problem with your airbag system. In this case, you should take your car to a qualified mechanic for diagnosis and repair.
Please note that tampering with the airbag system can be dangerous. If you are not comfortable performing these steps, you should consult a qualified mechanic.
