Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the engine off.
Disconnect the battery (negative terminal) to prevent accidental airbag deployment.

2. Use OBD-II Scanner

Connect the OBD-II scanner to the vehicle’s diagnostic port (usually located under the dashboard).
Turn the ignition to the "ON" position without starting the engine.

3. Retrieve and Clear Codes

Navigate to the airbag system section on the scanner.
Select “Read Codes” to view the existing codes (B and C).
Once noted, select “Clear Codes” to erase them from the system.
Confirm the action on the scanner.

4. Reconnect Battery

Reconnect the negative terminal of the battery securely.
Ensure that all connections are tight to prevent future issues.

5. Final Checks

Turn the ignition to the "ON" position again and check if the warning lights illuminate.
Start the engine and observe if the lights remain off.
