Solution

1. Preparation

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

2. Scan for Error Codes

Connect the OBD-II scanner to the diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Read and record any DTCs related to the airbag system.

3. Inspect Airbag Components

Remove the steering wheel airbag and dashboard airbag as necessary following manufacturer guidelines.
Inspect the wiring harnesses and connectors for corrosion, loose connections, or damage.
Replace any damaged connectors or wiring.

4. Check Battery Voltage

Use a multimeter to measure the battery voltage.
If the voltage is below 12.4V, charge the battery or replace it if necessary.

5. Reset the System

After addressing any faults found, use the OBD-II scanner to clear any stored DTCs.
Reconnect the negative battery terminal.

6. Test the System

Start the vehicle and observe whether the airbag light remains illuminated.
Perform a self-test of the airbag system if the vehicle supports it.
