Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, screwdriver.
Ensure the vehicle is in park and the ignition is turned off.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Inspect Seatbelt and Buckle

Remove any obstructions around the seatbelt and buckle.
Check for fraying or damage to the seatbelt webbing.
Ensure the buckle clicks securely into place and releases properly.

3. Test Seat Occupancy Sensor

Locate the seat occupancy sensor under the seat (typically integrated into the seat cushion).
Disconnect the connector and use a multimeter to test the sensor's resistance:
- The resistance should be within the specifications outlined in the service manual.
Replace the sensor if it shows an open circuit or resistance outside the specified range.

4. Check Wiring and Connections

Inspect the wiring harnesses under the seats for any signs of damage or corrosion.
Ensure all connections are secure and free from dirt or moisture.
Repair or replace any damaged wiring as needed.

5. Clear Fault Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored fault codes related to the seatbelt system.
Perform a test drive to see if the seatbelt warning light reappears.
