Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the ignition off.
Disconnect the negative battery cable and wait for at least 10 minutes to allow the system to discharge.

2. Inspect Airbag System

Locate the airbag system connectors under the driver's side dashboard.
Check for any loose connections, damage, or corrosion.
If necessary, clean the connectors with electrical contact cleaner and reconnect securely.

3. Scan and Clear Codes

Reconnect the battery.
Turn the ignition to the "On" position without starting the engine.
Connect the OBD-II scanner and select the airbag module.
Read any stored trouble codes and note them.
Use the scanner to clear the codes.
Turn the ignition off and then back to the "On" position to check if the airbag light is still illuminated.

4. Test the System

Start the engine and observe if the airbag light remains off.
If the light is still on, further diagnostics may be necessary to identify deeper issues in the airbag system.
