Locate the airbag control module, typically found beneath the center console or beneath the driver's seat.
Ensure all connectors are securely attached.
If necessary, test the module using the appropriate diagnostic equipment to ensure it is functioning correctly.

5. Inspect Seat Belt Sensors

Check the seat belt buckle and pretensioner connectors.
Ensure that the sensors are functioning correctly and that there are no obstructions or damage.

6. Reconnect Battery and Test

Reconnect the negative battery cable.
Start the vehicle and observe if the airbag light remains illuminated.
Perform a test drive to ensure the light does not reappear and all systems function correctly.
