Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery and wait for at least 10 minutes to prevent accidental deployment of airbags.
Ensure the workspace is clear and safe.

2. Scan for Codes

Use the OBD-II scanner to retrieve and document any DTCs.
Clear the codes and check if the airbag light returns after starting the vehicle.

3. Inspect Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the airbag system-related fuses and check for continuity using a multimeter.
Replace any blown fuses with the correct rating as specified in the owner's manual.

4. Check Wiring and Connectors

Inspect the wiring harnesses leading to the airbag system for fraying or breaks.
Ensure connectors are seated properly and free from dirt or moisture.
Repair any damaged wiring with solder and heat shrink tubing or electrical connectors.

5. Inspect Airbag Modules

Remove the necessary trim panels to access the airbag modules if physical inspection is needed.
Look for any signs of deployment, damage, or corrosion on the connectors.

6. Reconnect Battery and Test

Reconnect the vehicle's battery and ensure all connections are secure.
Start the vehicle and monitor the airbag light; it should turn off if no issues remain.
