Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, screwdrivers, and a torque wrench.
Disconnect the vehicle's battery and wait for at least 10 minutes to ensure safety before working on the airbag system.

2. Retrieve Diagnostic Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve any stored airbag codes and document them for reference.
Clear the codes and observe if the airbag light returns after a test drive.

3. Inspect and Repair Connections

Remove the driver's and passenger's seats if necessary to access seat belt connectors and airbag wiring.
Check for loose or corroded connectors. Clean or replace any corroded connectors.
Ensure seat belt connections are functioning correctly; replace any faulty seat belt assemblies if needed.

4. Check Airbag Module

Locate the airbag control module, typically found beneath the center console or dashboard.
Inspect the module for any signs of damage or loose connections.
If codes indicate a fault in the module, consider replacement with a factory-authorized part.

5. Reassemble and Test

Reconnect the vehicle's battery and ensure all connections are secure.
Test the airbag system by starting the vehicle and checking if the airbag light remains off.
If the light is still on, recheck for codes and repeat the inspection process as required.
