Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery and allow it to sit for at least 10 minutes to ensure the airbag system is deactivated.

2. Inspect Wiring and Connectors

Remove the lower steering column cover to access airbag connectors.
Inspect the connectors and wiring for frayed or broken wires.
Clean any oxidation from the connectors using electrical contact cleaner.

3. Replace Faulty Components

If diagnostic steps indicate a faulty airbag module or sensor, carefully remove and replace the defective component.
- Tools Required: Socket set, Torx driver, electrical contact cleaner
- Safety Warning: Always handle airbags and components with care; they are sensitive devices.

4. Clear Trouble Codes

Reconnect the battery and turn on the ignition without starting the engine.
Use the OBD-II scanner to clear any trouble codes from the airbag system.

5. Test Airbag System

Perform a self-check of the airbag system by turning on the ignition; the airbag light should illuminate briefly and then turn off.
If the light remains on, further diagnostics may be needed.
