Solution

1. Preparation

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

2. Inspect Airbag Connectors and Wiring

Carefully remove the relevant trim panels to access the airbag connectors.
Check all connectors for tightness and signs of wear or corrosion.
Use a multimeter to test the continuity of the wiring between the airbag module and the connectors.
Repair or replace any damaged wiring or connectors.

3. Check and Replace Fuses

Locate the airbag system fuse in the fuse box.
Inspect the fuse for continuity using a multimeter.
Replace the fuse with one of the same amperage if it is blown.

4. Evaluate and Replace the Clock Spring (if necessary)

Remove the steering wheel using a socket set, ensuring to follow the manufacturer’s specifications for torque.
Disconnect the clock spring connectors.
Remove the clock spring from the steering column.
Install a new clock spring, ensuring it is centered and properly connected.

5. Reset Airbag System

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored airbag fault codes.
Turn the ignition to the “ON” position without starting the vehicle and wait for a few seconds to check if the airbag light turns off.
