Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdrivers, and safety gloves.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Inspect and Clean the Seatbelt Buckle

Remove any debris or dirt from the seatbelt buckle using a soft brush.
Check for any signs of wear or physical damage.
If necessary, lubricate the buckle lightly with silicone spray.

3. Check Seatbelt Sensor Wiring

Locate the wiring harness connected to the seatbelt buckle.
Disconnect the harness and visually inspect for any damage.
Use a multimeter to check continuity across the wires; repair or replace as needed.

4. Test Seatbelt Buckle Sensor

With the multimeter, set it to the resistance setting.
Connect the multimeter probes to the seatbelt sensor terminals.
Confirm that the readings are within specifications; typically, resistance should be close to zero when the buckle is latched and infinite when unlatched.
Replace the sensor if readings are outside the specified range.

5. Clear Diagnostic Codes

Reconnect the OBD-II scanner to the vehicle's port.
Clear any trouble codes related to the seatbelt or airbag system.
Disconnect the scanner and start the vehicle to check if the warning light has turned off.
