Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, torque wrench
Disconnect the vehicle's battery and wait for at least 10 minutes to ensure all systems are powered down.

2. Retrieve and Analyze Codes

Connect the OBD-II scanner to the diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Retrieve and note any error codes related to the airbag system for further analysis.

3. Inspect Fuses

Locate the fuse box and identify the airbag system fuses (refer to the owner's manual for location).
Use a multimeter to check for continuity on the airbag fuses.
Replace any blown fuses with new ones of the same amperage.

4. Check Connections

Remove the driver's seat to access the airbag connectors beneath.
Inspect all connectors and wiring for signs of damage, corrosion, or loose connections.
Reconnect any loose connectors and secure all wiring.

5. Test Passenger Seat Occupancy Sensor

Access the passenger seat and locate the occupancy sensor.
Use a multimeter to check the resistance of the sensor when the seat is occupied and unoccupied.
Replace the sensor if it is not functioning within the specified resistance range.

6. Reconnect Battery and Clear Codes

Reconnect the vehicle’s battery.
Use the OBD-II scanner to clear any stored airbag error codes.
Turn the ignition back on to check if the airbag light has turned off.
