Solution

1. Preparation

Ensure the vehicle is parked on a flat surface with the ignition off.
Disconnect the negative battery terminal to prevent accidental airbag deployment.
Gather tools: OBD-II scanner, socket set, multimeter, and screwdrivers.

2. Diagnose and Clear Codes

Connect the OBD-II scanner to the vehicle’s OBD port.
Retrieve and document any airbag-related error codes.
Clear the codes and see if the airbag light returns after a test drive.

3. Repair Faulty Components

If error codes indicate specific components (e.g., seatbelt buckle, airbag module), replace them as necessary.
- Example for seatbelt buckle:
  1. Remove the seat cushion or trim to access the seatbelt buckle wiring.
  2. Disconnect the old buckle and install the new one, ensuring connections are secure.
  3. Reassemble the seat cushion or trim.

4. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check if the airbag light remains off.
Conduct a test drive to ensure airbag system functionality.

5. Final Inspection

If the airbag light remains illuminated, further diagnostics may be needed.
Inspect all connections and components again for any overlooked issues.
