Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative terminal of the battery and wait for at least 10 minutes to ensure capacitors are discharged.

2. Inspect Airbag System Components

Wiring and Connectors:
- Remove the driver and passenger side lower dash covers using a socket set.
- Visually inspect all airbag-related wiring and connectors for damage or corrosion.
- Repair or replace damaged wiring as necessary.
Seatbelt Connections:
- Check the seatbelt pretensioner connectors underneath the front seats.
- Ensure that seatbelt connections are secure and free of damage.

3. Check Airbag Module

Locate the airbag control module, typically found under the center console or dashboard.
Inspect the module for any visible damage or loose connections.
Tighten any loose connections and replace the module if found defective.

4. System Reset

Reconnect the negative terminal of the battery.
Use the OBD-II scanner to clear any DTCs from the airbag system.
Turn on the ignition and observe if the airbag light remains off.
