Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to avoid accidental airbag deployment.
Allow the vehicle to sit for at least 10 minutes before proceeding to ensure system discharge.

2. Inspect and Repair Wiring

Tools Required: Multimeter, wire crimping tool, electrical tape.
Check all relevant wiring harnesses for continuity using a multimeter.
Repair or replace any damaged wiring or connectors identified during the inspection.
Secure all connections with electrical tape to prevent exposure to moisture.

3. Replace Faulty Components

Parts Required: Airbag module or seatbelt sensor (if identified as faulty).
Remove the driver's and passenger's seats if necessary to access seatbelt sensors.
Disconnect the old component, ensuring to note any connector positions.
Install the new component, making sure all connections are secure and properly seated.

4. Clear Codes and Test

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any DTCs from the airbag system.
Start the vehicle and observe if the airbag light remains off after a few minutes of operation.
