Solution

1. Preparation

Gather tools and parts needed.
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 Fault Codes

Connect the OBD-II scanner and retrieve any stored DTCs.
Clear the codes and observe if they return after starting the vehicle.
If specific codes are identified, address them according to the manufacturer's service manual guidelines.

3. Inspect and Repair Fuses

Locate the fuse box and identify the airbag system fuses.
Use a multimeter or test light to check for continuity.
Replace any blown fuses with the same amperage rating.

4. Check Connectors and Wiring

Remove the driver's and passenger's seat covers if necessary to access the connectors.
Inspect all airbag system connectors for corrosion, dirt, or loose connections.
Clean or repair any damaged wiring or connectors.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and confirm that the airbag warning light has turned off.
If the light remains on, further diagnostics may be required.
