3. Remove the fuses and visually inspect them for damage.
4. Replace any blown fuses with the correct amperage.
5. Reconnect the battery and check if the airbag light is still on.

3. Check Airbag Module and Wiring

Sub-steps:
1. Locate the airbag module, typically under the center console or near the driver's seat.
2. Disconnect the module connector and inspect for corrosion or damage.
3. Use a multimeter to test the wiring for continuity and check for shorts.
4. Repair or replace any damaged components as necessary.
5. Reconnect the module, ensuring it is secure and properly seated.

4. Inspect Seatbelt Sensors

Sub-steps:
1. Locate the seatbelt sensors, usually found in the buckle or latch assembly.
2. Disconnect the connectors and visually inspect for any damage.
3. Use a multimeter to test the sensors for proper operation.
4. Replace any faulty sensors with OEM parts.
5. Reconnect the sensors and check for secure fitment.

5. Clear Codes and Test

Sub-steps:
1. Use the OBD-II scanner to clear any error codes related to the airbag system.
2. Reconnect the battery.
3. Start the vehicle and observe the airbag light during the ignition cycle.
