Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdrivers.
Disconnect the vehicle's battery to ensure safety while working on electrical components.
Allow the vehicle to cool down if it was recently operated.

2. Inspect and Test Seatbelt Connectors

Locate the seatbelt connectors under the front seats.
Disconnect each seatbelt connector and visually inspect for damage or corrosion.
Use a multimeter to check for continuity across the connectors; replace if faulty.

3. Test Seatbelt Latch Sensors

Remove the seatbelt latch from its housing.
Use the multimeter to test the sensor for proper operation by engaging and disengaging the latch; replace if it does not show continuity when engaged.

4. Check the Instrument Cluster

Remove the instrument cluster using a socket set and screwdriver.
Inspect the warning light bulb for functionality; replace if burnt out.
Reinstall the instrument cluster securely.

5. Reconnect Battery and Clear Codes

Reconnect the vehicle's battery.
Use the OBD-II scanner to clear any diagnostic trouble codes stored in the system.
Start the vehicle and observe the operation of the seatbelt warning light.
