Solution

1. Preparation

Gather tools and parts.
Disconnect the negative battery terminal to prevent accidental airbag deployment.
Allow the vehicle to sit for at least 10 minutes after disconnecting the battery.

2. Inspect the Fuse

Locate the fuse box, typically found under the dashboard on the driver’s side.
Use the fuse puller to remove the airbag fuse (consult the owner's manual for the exact location).
Inspect the fuse for continuity; replace if blown.

3. Check Wiring and Connections

Remove the driver's seat if necessary to access wiring underneath.
Inspect the connectors at the airbag module and under the seat for damage or corrosion.
Clean any corroded terminals with electrical contact cleaner and reconnect securely.

4. Test the Airbag Sensor

Use a multimeter to check the resistance of the airbag sensor.
Ensure the resistance falls within the manufacturer-specified range (consult service manual for specifications).
Replace the sensor if it is out of specification.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored airbag codes.
Perform a test drive to check if the airbag light remains off.
