Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to prevent any electrical issues during inspection.

2. Inspect Seatbelt Latches

Using a socket set, remove any panels necessary to access the seatbelt latches.
Clean the seatbelt latches and ensure they engage smoothly.
Reconnect any disconnected wires associated with the seatbelt mechanisms.

3. Check Seatbelt Sensors

Locate the seatbelt sensors at each seat (typically found in the buckle assembly).
Disconnect the electrical connector and inspect for corrosion or damage.
Use a multimeter to test the continuity of the sensor. Replace if faulty.

4. Inspect and Test Seat Sensors

If your model is equipped with seat sensors, check under the seat for any loose wiring or disconnections.
Ensure the connectors are firmly attached and test the seat sensor function using the OBD-II scanner to confirm it is reading correctly.

5. Reconnect Battery and Reset System

Reconnect the vehicle’s battery once all inspections and repairs are complete.
Use the OBD-II scanner to clear any error codes related to the seatbelt system.
Test the system by starting the vehicle and checking if the warning light has turned off.
