Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and a torque wrench.
Disconnect the negative battery terminal to prevent accidental deployment of airbags.
Allow the vehicle to sit for at least 15 minutes to ensure all systems are discharged.

2. Retrieve Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Retrieve and record any airbag-related error codes for further analysis.

3. Inspect Seatbelt Connections

Remove any trim or covers to access the seatbelt connectors.
Ensure all connections are secure and free from dirt or corrosion.
Replace any damaged seatbelt buckles if necessary.

4. Check Airbag Module and Wiring

Locate the airbag module, typically found under the center console or dashboard.
Visually inspect the module and wiring for signs of damage, such as fraying or corrosion.
Repair or replace any damaged components.

5. Examine Impact Sensors

Locate the impact sensors, usually mounted in front of the vehicle.
Check for proper alignment and secure mounting.
Replace any faulty sensors based on diagnostic results.

6. Repair or Replace Clock Spring

Remove the steering wheel by loosening the center bolt and disconnecting the airbag connections.
Carefully remove the clock spring from the steering column.
Install a new clock spring, ensuring proper alignment, and reassemble the steering wheel.
Reconnect the airbag connections securely.
