Solution

1. Preparation

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

2. Retrieve and Clear DTCs

Connect the OBD-II scanner to the vehicle's diagnostic port.
Power on the ignition without starting the engine and navigate to the airbag module.
Retrieve any stored DTCs and note them for further analysis.
Clear the DTCs and monitor if the airbag light returns after driving the vehicle.

3. Inspect and Repair Connectors

Remove the front seat(s) if necessary to access connectors beneath them.
Carefully disconnect and inspect the connectors related to the airbag system for corrosion or damage.
Clean any corrosion with electrical contact cleaner and reconnect securely.
If connectors are damaged, replace with new OEM parts.

4. Replace Blown Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the airbag system fuse using the fuse diagram.
Replace any blown fuses with the correct amperage rating as specified in the owner's manual.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and observe if the airbag warning light remains illuminated.
Conduct a test drive to verify that the airbag system is functioning properly and the light does not reappear.
