Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent accidental airbag deployment.

2. Inspect Wiring and Connectors

Remove the driver's side lower dash panel to access airbag wiring.
Visually inspect connectors for damage; repair or replace as necessary.
Use a multimeter to check continuity in the wiring harness.

3. Replace Faulty Components

If the seat occupancy sensor is faulty, replace it:
- Disconnect the wiring harness from the sensor.
- Remove the seat cushion as per the service manual.
- Install the new sensor and reconnect the wiring harness.
If the airbag control module is faulty:
- Locate the module, usually under the center console or dashboard.
- Disconnect the battery again, then remove the module by unscrewing it from its mounting.
- Install the new module and reconnect all wiring.

4. Reconnect Battery and Test

Reconnect the negative battery terminal securely.
Turn the ignition to the "ON" position without starting the engine.
Observe the airbag light; it should turn off after a few seconds if the issue is resolved.

5. Clear Error Codes

Use the OBD-II scanner to clear any stored airbag fault codes in the system.
Perform a short test drive to ensure the airbag light does not illuminate again.
