Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a flat surface and the ignition is off.
Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, safety glasses, and gloves.

2. Disconnect Battery

Disconnect the negative terminal of the battery to prevent accidental deployment of airbags.
Wait at least 15 minutes after disconnection to ensure systems are powered down.

3. Inspect and Repair Airbag Connectors

Remove the seat from the passenger side (if applicable) to access airbag connectors.
- Sub-steps:
  1. Use a socket set to unbolt the seat from the floor.
  2. Disconnect the electrical connectors carefully.
  3. Inspect for corrosion or loose connections; clean or reseat as necessary.
Reconnect connectors securely and reassemble the seat.

4. Replace Faulty Components

If error codes indicate a faulty seatbelt sensor or airbag module:
- Sub-steps:
  1. Remove the old seatbelt sensor or airbag module using a socket set.
  2. Install the new component, ensuring all connectors are properly secured.
  3. Torque bolts to manufacturer specifications (check repair manual for specific torque values).

5. Final Checks and Battery Reconnection

Reconnect the battery terminal.
Clear any error codes using the OBD-II scanner.
Start the vehicle and monitor the airbag light to ensure it does not illuminate.
