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 terminal of the battery to prevent accidental deployment.

2. Scan and Record Codes

Use an OBD-II scanner to scan for airbag-related codes.
Record all codes and their descriptions for reference.

3. Inspect Wiring and Connectors

Remove any necessary panels to access the airbag wiring.
Visually inspect the wiring harness and connectors for damage.
Repair or replace any damaged wires or connectors.

4. Check Airbag Control Module

Locate the airbag control module (usually under the front seats or center console).
Inspect the module for any physical damage or corrosion.
Reconnect any loose connections and ensure the module is securely mounted.

5. Test Airbag System

Reconnect the battery terminal.
Turn the ignition to the 'ON' position without starting the engine.
Use the OBD-II scanner to clear any fault codes and check if the airbag light turns off.
If the light remains on, further diagnosis of specific codes may be necessary.
