Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, flathead screwdriver, and safety glasses.
Safety Warnings: Disconnect the battery before working on the seatbelt system to avoid airbag deployment.

2. Inspect and Secure Connections

Locate the seatbelt connectors under the seats.
Disconnect and inspect each connector for corrosion or damage.
Clean the connectors using an electrical contact cleaner.
Reconnect the connectors securely and ensure they click into place.

3. Examine Seatbelt Buckles

Remove the seatbelt buckle assembly using a socket set.
Check for any debris or damage inside the buckle.
If debris is found, clean the buckle mechanism thoroughly.
If damaged, replace the buckle assembly with a new part.

4. Test Seatbelt Sensors

Use a multimeter to test the seatbelt sensor in the buckle.
Set the multimeter to continuity mode.
Insert the buckle into the latch and observe the multimeter; a change indicates proper function.
If there is no change, the sensor must be replaced.

5. Clear Fault Codes

Reconnect the battery after repairs.
Use the OBD-II scanner to clear any fault codes related to the seatbelt system.
Perform a system check to ensure the warning light does not re-illuminate.
