Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, and a Phillips screwdriver.
Disconnect the negative battery terminal to prevent accidental airbag deployment during the repair.
Allow the vehicle to sit for at least 10 minutes to ensure the airbag system is deactivated.

2. Retrieve and Address Diagnostic Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and document any airbag-related error codes.
Research the codes to determine the specific issue (e.g., faulty sensor, wiring issue).

3. Inspect and Repair Wiring/Connectors

Remove the necessary panels to access airbag system wiring.
Carefully inspect the wiring harness for damage, fraying, or corrosion.
Use a multimeter to test the continuity of the wiring.
Repair or replace any damaged wiring or connectors as needed.

4. Check and Replace Sensors (if necessary)

Inspect the seat occupancy sensor located under the passenger seat.
If the sensor is malfunctioning, disconnect the wiring and remove the sensor.
Replace the sensor with a new one and reconnect the wiring securely.

5. Clear Diagnostic Codes and Recheck System

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored diagnostic codes.
Start the vehicle and check if the airbag light remains off.
