Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and cleaning supplies.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the vehicle battery to avoid any electrical shorts.

2. Inspect and Clean Seatbelt Buckles

Remove the seatbelt buckle covers using a socket set.
Clean the buckle mechanism with electronic cleaner to remove any debris.
Check the electrical connector for the buckle; reseat if necessary.

3. Test Seatbelt Sensors

Using a multimeter, test the resistance of each seatbelt sensor.
- Disconnect the sensor connector.
- Measure continuity. A reading near zero indicates a good sensor; if there is no continuity, replace the sensor.
Reconnect the sensor once testing is complete.

4. Reconnect Battery and Clear Codes

Reconnect the vehicle battery.
Use the OBD-II scanner to clear any stored error codes related to the seatbelt system.
Start the vehicle to see if the warning light remains off.

5. Final Inspection

Test each seatbelt for proper function by engaging and disengaging.
Ensure the warning light turns off after the seatbelt is secured.
