Solution

1. Preparation

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

2. Retrieve Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition (without starting the engine) and read the error codes.
Document any codes related to the airbag system for reference.

3. Inspect and Replace Fuses

Locate the fuse box and refer to the diagram to identify airbag-related fuses.
Remove any blown fuses and replace them with new ones of the same amperage.
Reconnect the battery and check if the airbag light is still illuminated.

4. Check Wiring and Connectors

Remove the seats if necessary to access the airbag connectors.
Inspect the connectors for corrosion, dirt, or loose connections; clean or secure as needed.
Use a multimeter to test continuity in the wiring harness.

5. Reset Airbag System

If no issues are found with the wiring or components, use the OBD-II scanner to clear the error codes.
Recheck the airbag light; if it remains on, further diagnosis may be needed.
