Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative terminal of the battery to prevent accidental airbag deployment.

2. Retrieve and Address 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 any error codes indicating the airbag issue.
Depending on the error code, proceed to the next steps to troubleshoot specific components.

3. Inspect and Clean Seatbelt Connections

Remove the seat covers or trim panels if necessary to access the seatbelt connectors.
Disconnect the seatbelt connectors, clean the terminals with electrical contact cleaner, and reconnect them securely.
Ensure that the seatbelts are functioning properly and not frayed or damaged.

4. Check Airbag Control Module

Locate the airbag control module (usually under the center console or dashboard).
Inspect it for any signs of physical damage or corrosion.
If necessary, replace the airbag control module with a compatible unit according to the manufacturer's specifications.

5. Reconnect Battery and Clear Codes

Reconnect the negative terminal of the battery.
Use the OBD-II scanner to clear any stored airbag error codes.
Turn on the ignition and check if the airbag light remains off.
