Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench.
Disconnect the vehicle battery and wait at least 10 minutes to allow the airbag system to discharge.

2. Scan for 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 and note down any airbag-related trouble codes.

3. Inspect Wiring and Connectors

Remove the driver's side lower dash panel to access airbag wiring.
Visually inspect the wiring harnesses and connectors for signs of wear, corrosion, or disconnection.
Use a multimeter to test continuity in the wires.

4. Check Seatbelt Sensors and Pretensioners

Locate the seatbelt pretensioner connectors and inspect for proper connection.
If codes indicate a faulty pretensioner or seatbelt sensor, disconnect and replace the affected component as necessary.
Reconnect and ensure all connectors are secure.

5. Verify Airbag Control Module Function

If there are error codes related to the airbag control module, consider resetting the module.
If the light remains on after resetting, replacement of the airbag control module may be necessary.
Follow the specific manufacturer guidelines for module replacement and programming.
