Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, flathead screwdriver, torque wrench.
Disconnect the negative battery terminal to avoid accidental airbag deployment. Allow the vehicle to sit for at least 10 minutes before proceeding.

2. Scan for Codes

Using the OBD-II scanner, connect it to the diagnostic port under the dashboard.
Retrieve airbag-related error codes. Note the codes for reference.

3. Inspect Wiring and Connections

Remove the driver's side lower dash panel using a flathead screwdriver.
Inspect the wiring harness for the airbag module for any visible damage.
Check the connectors to ensure they are securely fastened and free from corrosion.

4. Check Fuses

Locate the fuse box (often under the dashboard or in the engine compartment).
Identify and inspect the airbag fuse. Replace if blown, using the specified amperage from the owner's manual.

5. Replace Faulty Components

If the error codes indicate a specific fault (e.g., airbag sensor or clock spring), proceed with the replacement of the faulty component.
For clock spring replacement:
- Remove the steering wheel using a socket set (ensure the steering wheel is centered).
- Remove the airbag module carefully, disconnecting the electrical connectors.
- Replace the clock spring, ensuring proper alignment.
- Reinstall the airbag module and steering wheel, torquing to manufacturer specifications.

6. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored error codes.
Confirm that the airbag light is no longer illuminated.
