Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the negative battery terminal to prevent accidental airbag deployment.

2. Retrieve and Analyze Error Codes

Use the OBD-II scanner to access the airbag control module.
Note the trouble codes that are present and refer to the service manual for specifics on each code.
Clear the trouble codes and see if they return after a short drive.

3. Inspect Wiring and Connectors

Visually inspect the wiring harnesses leading to the airbag system components.
Look for any frays, corrosion, or loose connections.
If damaged wires are found, repair or replace them as necessary.

4. Check Airbag Control Module

Locate the airbag control module, usually found under the center console or dashboard.
Verify that the module is securely connected and free from faults.
If the module is faulty, replace it with a new one, making sure to follow manufacturer specifications for installation.

5. Inspect and Replace Seatbelt Pretensioners

Check the seatbelt pretensioners for functionality by ensuring they are securely attached.
If a pretensioner is faulty, disconnect it and replace it with a new unit, ensuring all connections are secure.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check if the airbag light is still illuminated.
Test the airbag functionality by performing a self-check (if equipped).
