Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and a flathead screwdriver.
Disconnect the negative terminal of the battery to ensure safety while working on the airbag system.

2. Inspect and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Use the fuse puller to remove any fuses related to the airbag system and check for continuity using a multimeter.
Replace any blown fuses with the same amperage rating.

3. Check and Secure Seatbelt Connections

Inspect the seatbelt buckle connectors for proper engagement.
Disconnect and reconnect the connectors under the seats to ensure a good electrical connection.
If necessary, replace any damaged seatbelt buckles.

4. Examine Wiring and Connectors

Remove the seat cushions if needed to access the wiring harness under the seats.
Look for frayed wiring or loose connectors; repair or replace as necessary.
Ensure all connectors are fully seated and locked into place.

5. Clear Codes and Test

Reconnect the battery terminal.
Use the OBD-II scanner to clear any error codes from the airbag control module.
Take the vehicle for a test drive to check if the airbag light reappears.
