Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, and trim removal tools.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the vehicle battery and wait at least 10 minutes to allow any residual power to dissipate.

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and note any DTCs related to the airbag system.
Clear the codes from the system and turn the ignition back on to check if the light returns.

3. Inspect Electrical Connections

Remove the seat cushions (if applicable) using the socket set to access connectors.
Check the connectors for tightness and corrosion; clean any corroded connections with electrical contact cleaner.
Reconnect the connectors securely.

4. Replace Faulty Components

If any DTCs indicate a specific faulty component (e.g., airbag module, sensors), replace them as per the manufacturer's specifications.
Follow the replacement process outlined in the vehicle's service manual for the specific component.

5. Reconnect Battery and Test

Reconnect the vehicle battery and ensure all connections are secure.
Start the vehicle and observe whether the airbag light remains off after the initial self-check.
