Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent accidental airbag deployment.
Ensure the vehicle is in a safe position (parked on a level surface with the ignition off).

2. Inspect and Clean Seatbelt Buckles

Remove any debris from the seatbelt buckles using compressed air or a soft brush.
If the buckles are damaged, replace them with OEM parts.

3. Repair or Replace Wiring Harness

If wiring damage is found, repair any frayed wires with solder and heat shrink tubing, or replace the entire harness if necessary.
Ensure all connections are secure and free from corrosion.

4. Test and Replace Sensors

Use a multimeter to test the seatbelt and occupancy sensors for proper resistance values.
If a sensor is defective, replace it with an OEM component.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any error codes that were logged during diagnostics.

6. Final Assembly and Testing

Ensure all components are securely reassembled.
Test the seatbelt warning light by starting the vehicle and checking if the light turns off upon fastening the seatbelt.
