Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, multimeter, and replacement fuses if necessary.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent accidental deployment of the airbags.

2. Scan for Trouble Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Retrieve any stored trouble codes related to the airbag system and note them for further diagnosis.

3. Inspect Fuses

Locate the fuse box (typically under the dashboard and/or in the engine compartment).
Identify the specific fuse for the airbag system using the fuse diagram.
Remove the fuse and inspect it. If blown, replace it with a fuse of the same amperage.

4. Check Wiring and Connections

Inspect the wiring under the driver's seat and passenger seat for any frayed wires or loose connections.
Ensure that the connectors are properly seated and free from corrosion.
If any connections are damaged, repair or replace the wiring as necessary.

5. Test Seat Occupancy Sensor

If equipped, use a multimeter to test the seat occupancy sensor for proper resistance values.
Replace the seat occupancy sensor if readings are out of specification or if it is malfunctioning.

6. Clear Codes and Reconnect Battery

After repairs are made, reconnect the battery.
Use the OBD-II scanner to clear any trouble codes.
Turn the ignition to the "ON" position and check if the airbag light is still illuminated.
