Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent accidental deployment of airbags.

2. Inspect and Replace Fuses

Locate the fuse box (typically under the dash or in the engine compartment).
Use a fuse puller or needle-nose pliers to remove the airbag system fuse.
Inspect the fuse; if blown, replace it with one of the same amperage.
Reinstall the fuse and reconnect the battery terminal.

3. Check Airbag Connections

Remove the driver's side lower dash cover to access the airbag module.
Inspect the wiring harnesses connected to the airbag module for signs of damage or disconnection.
Ensure all connectors are securely plugged in; repair or replace any damaged wiring.

4. Reset Airbag System

Reconnect the battery terminal and turn the ignition to the "On" position without starting the engine.
Use an OBD-II scanner to clear any stored airbag codes.
Turn the ignition off, then on again to check if the airbag light remains off.

5. Test Airbag System

Conduct a visual inspection of the airbag deployment area (steering wheel, dashboard, etc.).
Test drive the vehicle to ensure the airbag light does not reappear.
Monitor the system for any unusual behaviors or warning lights.
