Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the battery to prevent electrical shorts.

2. Inspect Seatbelt Latch

Remove the seatbelt from the seatbelt anchor point.
Inspect the latch for any foreign objects or wear.
Clean the latch area with compressed air or a soft brush if necessary.

3. Check Wiring Connections

Locate the seatbelt warning sensor wiring under the seat.
Disconnect the connector and inspect for corrosion or damage.
Reconnect the wiring harness ensuring a secure fit.

4. Test Seatbelt Warning Functionality

Reconnect the battery and turn the ignition to the "ON" position (do not start the engine).
Manually buckle and unbuckle the seatbelt to see if the warning system activates.
If the warning activates, the issue may have been a dirty latch or poor connection.

5. Inspect and Replace Fuse (if necessary)

Locate the fuse box under the dashboard or in the engine compartment.
Identify the fuse related to the seatbelt warning system (consult the owner's manual for the exact location).
Remove the fuse and inspect it; if broken, replace it with a fuse of the same amperage.
