Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and a flathead screwdriver.
Ensure the vehicle is parked on a flat surface with the ignition off.
Disconnect the negative battery terminal to prevent accidental deployment of the airbag.

2. Inspect and Reset Airbag Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition on without starting the engine.
Retrieve airbag-related trouble codes and note them down for reference.
If necessary, clear the codes and see if the light returns after a short drive.

3. Check Seat Occupancy Sensor

Remove the passenger seat cushion if necessary, using a socket set to unbolt it from the floor.
Locate the seat occupancy sensor connector under the seat.
Inspect the connector for corrosion, dirt, or damage; clean or repair as needed.
Ensure the sensor is properly seated and connected.

4. Inspect Wiring and Connections

Check all wiring harnesses connected to the airbag system, particularly under the passenger seat.
Look for frayed wires or loose connections.
Use a multimeter to test continuity in any suspect wiring.

5. Reassemble and Test

Reinstall the passenger seat cushion and ensure it is securely bolted.
Reconnect the negative battery terminal.
Start the vehicle and check if the passenger side airbag light remains off.
