Solution

1. Preparation

Gather necessary tools and safety equipment.
Disconnect the negative battery cable to prevent accidental deployment of airbags.
Wait at least 10 minutes after disconnecting the battery before proceeding to allow the system to discharge.

2. Inspect Connections

Remove the airbag module from the steering wheel or dashboard as applicable.
Check all electrical connectors for corrosion, dirt, or bent pins; clean or repair as needed.
Ensure that the connections are secure and properly seated before reassembly.

3. Replace Faulty Components

If diagnostic codes indicate a faulty airbag sensor or module, replace the affected component.
- For example, if a front airbag sensor is faulty, remove the old sensor and install the new one, ensuring it is correctly aligned and secured.
Utilize torque specifications provided by the manufacturer when reinstalling any components.

4. Clear Codes and Test

Reconnect the negative battery cable.
Use the OBD-II scanner to clear any trouble codes from the airbag system.
Turn the ignition on and verify that the airbag light is no longer illuminated.
