Solution

1. Preparation

Gather necessary tools including an OBD-II scanner, multimeter, socket set, and screwdrivers.
Disconnect the negative battery terminal to prevent accidental deployment of airbags while working.

2. Inspect and Repair Wiring

Remove the seatbelt buckle cover to access the wiring harness.
Visually inspect the wiring for fraying or disconnection.
If damaged, splice in new wiring or replace the entire harness as necessary.
Reconnect the wiring securely and reattach the cover.

3. Test and Replace Seatbelt Buckle Sensor

Remove the seatbelt buckle from the seat.
Disconnect the wiring connector from the buckle.
Using a multimeter, check for continuity across the terminals of the sensor.
If no continuity is detected, replace the seatbelt buckle assembly.
- To replace:
  - Remove the old buckle by unscrewing the mounting bolts.
  - Install the new buckle and secure it with bolts to the seat structure.
  - Reconnect the wiring harness.

4. Reset Warning Light

Reconnect the negative battery terminal.
Turn the ignition to the ON position (without starting the engine) for about 10 seconds.
Turn the ignition off and then back on to check if the seatbelt warning light has reset.
