Check the connections under the driver and passenger seats for the airbag harness.
Ensure all connectors are secure and free of corrosion.

4. Resetting the Airbag Light

Turn the ignition switch to the "ON" position without starting the engine.
Wait for about 10 seconds, then turn the ignition switch to the "OFF" position.
