1. Preparation

Gather tools and parts needed for repair.
Disconnect the negative terminal of the battery to ensure safety during repairs.

2. Inspect and Clean Seatbelt Buckle

Remove the seatbelt buckle from the mounting point.
Clean the connector and surrounding area with electrical cleaner.
Inspect the buckle for wear or damage and replace if necessary.

3. Check and Replace Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Refer to the fuse diagram to identify the seatbelt warning fuse.
Use a fuse puller or needle-nose pliers to remove the fuse and inspect it for damage.
Replace with a new fuse of the same amperage if blown.

4. Test Seatbelt Sensor

Reconnect the seatbelt buckle and ensure it clicks securely.
Use a multimeter to test the seatbelt sensor for proper voltage and resistance.
If the readings are outside the specified range, replace the seatbelt sensor.

5. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Start the vehicle and check if the seatbelt warning system activates when the seatbelt is unbuckled.
