Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, and basic hand tools (screwdrivers, socket set).
Ensure the vehicle is in a safe, well-ventilated area with the ignition off.

2. Scan and Clear Codes

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.
Follow the scanner's prompts to retrieve and record airbag error codes.
Clear the codes using the scanner and turn off the ignition.

3. Inspect Wiring and Connectors

Visually inspect all airbag-related wiring and connectors for any signs of damage, corrosion, or loose connections.
If any damaged wires are found, repair or replace them as necessary.

4. Test Seatbelt Sensors

Using a multimeter, test the resistance of the seatbelt sensors to ensure they are functioning within specified limits.
Replace any faulty sensors if they do not meet specifications.

5. Final Check

Reconnect any connectors that were disconnected during the inspection.
Turn the ignition back to the "On" position and check if the airbag light remains off after clearing codes.
