Faulty sensors in the seatbelt buckle can cause warning lights to activate.

• Use a multimeter to test the sensor for continuity.
• If the sensor fails the continuity test, it may need to be replaced.
• Consult the vehicle’s manual for the sensor’s specifications and testing procedure.

5. Replace the seatbelt buckle

If the seatbelt buckle is damaged or the sensors are faulty, replace it with a new or refurbished part.

• Remove the screws or bolts securing the seatbelt buckle using a socket wrench.
• Disconnect the wiring harness attached to the buckle.
• Attach the new buckle and secure it with screws or bolts.
• Reconnect the wiring harness and ensure it fits snugly.

6. Reset the airbag system

After completing repairs, reset the airbag system to clear warning lights and ensure proper operation.

• Use a diagnostic scanner to reset the airbag control module.
• Follow the scanner’s prompts to clear error codes and verify that the issue is resolved.
• If the warning lights persist, recheck the connections and components.

7. Reconnect the battery

Once all repairs and tests are complete, reconnect the vehicle’s battery.

• Tighten the battery terminals securely to ensure proper electrical flow.
• Start the vehicle and check the dashboard for warning lights.
