Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent accidental deployment of the airbags.
Gather tools: OBD-II scanner, socket set, multimeter, and a flathead screwdriver.

2. Fuse Inspection

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and identify the airbag fuse using the diagram on the cover or the owner’s manual.
Use a multimeter to check for continuity in the fuse. Replace if blown with a new fuse of the same amperage.

3. Wiring and Connector Check

Visually inspect the wiring harness that connects to the airbag system, ensuring there are no frayed wires or loose connections.
Disconnect the connectors and clean them with electrical contact cleaner if corrosion is present.
Reconnect and ensure all connections are secure.

4. Component Testing

If diagnostic codes indicate specific airbag components (e.g., side airbags or seat sensors), remove the necessary panels to access these components.
Use a multimeter to test resistance as specified in the service manual for each component and replace any malfunctioning parts.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any diagnostic trouble codes and reset the airbag light.
Perform a system check to ensure that the airbag light remains off after the reset.
