Solution

1. Preparation

Gather tools and parts: OBD-II scanner, socket set, multimeter, torque wrench, and a replacement airbag sensor if needed.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the negative terminal of the battery to disable the airbag system.

2. Retrieve and Clear Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Retrieve any error codes related to the airbag system and write them down.
Clear the codes and check if the airbag light remains off after starting the vehicle.

3. Inspect Wiring and Connectors

Visually inspect the wiring harnesses leading to the airbag modules and sensors.
Look for frayed wires, corrosion, or loose connections.
Use a multimeter to check for continuity in the wires and proper voltage at the connectors.
Repair or replace any damaged components as necessary.

4. Check Seatbelt and Impact Sensors

Test the seatbelt buckles for proper operation using the multimeter.
Ensure that the impact sensors are securely mounted and undamaged.
Replace any faulty seatbelt buckle or impact sensor as needed.

5. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Start the vehicle and check if the airbag light remains off.
If the light remains illuminated, further diagnostics may be needed, or consider replacing the airbag control module.
