Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, and a flashlight.
Disconnect the negative battery terminal to ensure safety while working on the airbag system.
Allow the vehicle to sit for at least 10 minutes before working to ensure capacitors discharge.

2. Retrieve Error Codes

Connect the OBD-II scanner to the diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Retrieve and document any error codes related to the airbag system.

3. Inspect Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the airbag fuse and inspect it for continuity using a multimeter.
Replace any blown fuses with the same amperage rating.

4. Check Connectors and Wiring

Slide the front seats forward to access the connectors underneath.
Disconnect and reconnect the airbag connectors to ensure proper contact.
Inspect wiring for any signs of wear, fraying, or disconnection.

5. Clear Error Codes

After repairs are completed, use the OBD-II scanner to clear any error codes.
Turn the ignition off, then back on to see if the airbag light remains off.

6. Reconnect Battery

Reconnect the negative battery terminal securely.
Ensure all tools are removed from the vehicle.
