Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the ignition off.
Disconnect the negative battery terminal to prevent electrical short circuits.

2. Inspect and Clean Seatbelt Latch

Remove the seatbelt from the buckle.
Inspect the latch and buckle for dirt or debris; clean with a cloth if necessary.
Apply a small amount of lubricant (e.g., silicone spray) to the latch if it appears sticky.

3. Check and Replace Fuse

Locate the fuse box; refer to the owner's manual for the exact location.
Identify the fuse associated with the seatbelt warning system.
Use a fuse puller or pliers to remove the fuse and inspect for damage.
Replace with a new fuse of the same amperage if blown.

4. Test Seatbelt Sensor

Reconnect the negative battery terminal.
With the ignition in the "ON" position (but not starting the engine), use a multimeter to check the continuity of the seatbelt sensor.
Disconnect the seatbelt connector and measure the resistance; it should show continuity when the seatbelt is buckled and no continuity when unbuckled.
Replace the seatbelt buckle assembly if the sensor is faulty.

5. Reassemble and Test

Reconnect any wiring or connectors that were disconnected during the process.
Reattach the seatbelt if it was removed.
Reconnect the negative battery terminal.
Start the vehicle and test the seatbelt warning light by unbuckling the seatbelt.
