Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the battery: Remove the negative terminal first to prevent electrical shock.

2. Inspect and Repair Airbag System

Check Airbag Module Connections:
- Locate the airbag control module (usually under the center console or dashboard).
- Disconnect the wiring harness from the module; inspect for damage or corrosion.
- Clean the contacts with electrical contact cleaner and reconnect.
Inspect Sensors and Wiring:
- Locate the front and rear airbag sensors (typically near the front bumper and rear seat).
- Check for secure connections and any visible damage to wiring.
- Repair or replace damaged wiring as necessary.
Check Seatbelt Pretensioners:
- Inspect the pretensioner connectors on the front seats.
- Ensure they are securely connected and not damaged.
- Replace any faulty pretensioners if necessary.

3. Reconnect Battery and Test

Reconnect the negative battery terminal securely.
Turn on the ignition and monitor the airbag light status.
Perform a test drive to check if the airbag light remains off.
