Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery and wait at least 10 minutes to ensure all systems are powered down.
Ensure the vehicle is in a well-ventilated area and that the steering wheel is straight.

2. Retrieve and Clear Fault Codes

Use the OBD-II scanner to read the stored fault codes.
Note down any codes for further analysis.
Clear the fault codes to determine if the issue recurs.

3. Inspect Wiring and Connectors

Check the connectors under the seats for tightness and corrosion.
Ensure that no wires are pinched or damaged.
Reconnect any loose connectors and secure them properly.

4. Replace Clock Spring (if necessary)

Remove the steering wheel using a socket set (typically requires a Torx bit).
Disconnect the clock spring harness and remove the faulty clock spring.
Install the new clock spring, ensuring that it is centered and aligned properly.
Reconnect the steering wheel and torque to manufacturer specifications.

5. Check and Replace Fuses

Locate the fuse box and identify the airbag fuses using the diagram.
Remove the fuses and inspect them for continuity using a multimeter.
Replace any blown fuses with new ones of the same amperage.

6. Reconnect Battery and Test

Reconnect the vehicle battery.
Start the vehicle and monitor the airbag light to see if it remains illuminated.
If the light is still on, further diagnostics may be needed.
