Solution

1. Preparation

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

2. Inspect Seatbelt Components

Remove the seatbelt from the retractor by locating the mounting bolt and using a socket set to unscrew it.
Examine the seatbelt for any frays, tears, or signs of wear.
Clean the seatbelt latch mechanism with a dry cloth to remove any dirt or debris.

3. Check Seatbelt Sensor

Locate the seatbelt buckle connector under the seat.
Disconnect the connector and use a multimeter to test for continuity across the terminals. A reading of zero ohms indicates a good sensor.
If the sensor is faulty, replace it with a new unit.

4. Inspect Wiring and Connectors

Carefully check the wiring harness leading to the seatbelt system for any visible damage.
If any connectors are corroded, clean them using electrical contact cleaner and ensure a tight connection.

5. Reassemble and Test

Reattach the seatbelt retractor and ensure it is secured with the mounting bolt at the specified torque (typically around 30 Nm).
Reconnect the battery and turn on the ignition to check if the seatbelt light is off.
If the light remains on, consider resetting the airbag system using a professional tool.
