Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.

2. Inspect Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the fuse associated with the seatbelt warning light.
Inspect the fuse for continuity; replace if blown.
Reinstall the fuse and reconnect the battery.

3. Check and Replace Seatbelt Sensor

If the fuse is functional, remove the seatbelt buckle assembly.
Disconnect the electrical connector from the seatbelt sensor.
Test the sensor with a multimeter; it should show continuity when the seatbelt is buckled.
If faulty, replace the seatbelt buckle assembly with a new one.
Reattach all connectors and reinstall the assembly.

4. Test the System

Reconnect the battery after all repairs.
Turn on the ignition and check if the seatbelt warning light illuminates properly.
Buckle and unbuckle the seatbelt to verify the warning system functions correctly.
